1. “How hydrogen could help us to reach net zero”

   https://hydeploy.co.uk/about/news/how-hydrogen-could-help-us-to-reach-net-zero/

   “One of the big areas that must be considered in introducing hydrogen to the gas mix is the impact to calorific value (CV). The CV drops when hydrogen is blended in, which means that more gas must be used to get the same amount of energy at the point of use. We have therefore trialled different blends containing different levels of hydrogen to optimise the output without incurring excessive cost, with 20% hydrogen currently coming out as the most favourable option from a lab perspective.”

   So is methane (natural gas) to be replaced 100% by hydrogen or only 20%? If only 20%, what’s the point?

2. I think a key problem with hydrogen is that we intend to replace a perfectly good system – natural gas boilers – with a system that will be more dangerous, more expensive, and will cause all sorts of upheaval re: digging up existing pipes. In other words the new system has a large heap of disadvantages, and its only advantage is that there are no carbon atoms in the gas.

   If on the other hand the new system was in some way better, then I could see perhaps justifying some of the downsides. When every house had a coal fire, plumbing in gas was clearly an enormous improvement of people’s lives, even if there were attendant risks.

   The release of water vapour is not a problem however, because of rain! If substantial amounts of CO2 snowed on Antarctica then there would probably be no issue with CO2 either (as far as I know this does not happen, even when the temperature drops below the freezing point of CO2 – perhaps the air pressure is too low at the height this could potentially happen).

3. “Hydrogen
   An Elemental Shift in How We Use Energy”

   https://www.certifhy.ca/index.html

   “~95% of the hydrogen produced in the world today is derived from fossil fuels. So while hydrogen itself is a clean alternative, the fact that most of it comes from fossil fuels makes using this hydrogen counterproductive.

   BUT

   An increasing amount of hydrogen is being generated from clean source (e.g. through water electrolysis using renewable or low-carbon electricity)”

   I can’t help thinking common sense has gone out of the window somewhere along the road.

4. Here is what an ordinary (coal) gas explosion did at Ronan Points in London in 1968.
   However, hydrogen is much more explosive than coal and/or natural gas. Therefore, will we need to upgrade all of our high-rise buildings to be resistant to hydrogen explosions?

5. Angusmac, good question. I thought the report had been sensible by assessing the challenge of conversion in respect of a two storey, masonry-built, terraced house with a basement and a loft conversion. Maybe, however, they were avoiding the difficult question of what to do with high-rise buildings? It ain’t going to be easy, that’s for sure.

8. “Climate: WWF warns UK spending is lagging behind targets”

   https://www.bbc.co.uk/news/uk-politics-58170865

   This is the usual propaganda from WWF and Harrabin, but right at the end of the article we get this:

   “Hydrogen warning
   One of the government’s new policy initiatives is to promote hydrogen as a power source. A hydrogen strategy is due soon.

   Lobby groups are pressing for widespread hydrogen use in home heating.

   But a report from Cornell and Stanford Universities warns that using hydrogen could increase emissions overall unless it’s made by electrolysis from surplus wind power.

   That’s because the most common current method of getting hydrogen is to split it from natural gas, which produces high carbon emissions.”

   “UK plan to replace fossil gas with blue hydrogen ‘may backfire’
   Academics warn ‘fugitive’ emissions from producing hydrogen could be 20% worse for climate than using gas”

   https://www.theguardian.com/environment/2021/aug/12/uk-replace-fossil-gas-blue-hydrogen-backfire-emissions

   “The government’s plan to replace fossil gas with “blue” hydrogen to help meet its climate targets could backfire after US academics found that it may lead to more emissions than using gas.

   In some cases blue hydrogen, which is made from fossil gas, could be up to 20% worse for the climate than using gas in homes and heavy industry owing to the emissions that escape when gas is extracted from the ground and split to produce hydrogen.

   The process leaves a byproduct of carbon dioxide and methane, which fossil fuel companies plan to trap using carbon capture technology. However, even the most advanced schemes cannot capture all the emissions, leaving some to enter the atmosphere and contribute to global heating.

   Professors from Cornell and Stanford universities calculated that these “fugitive” emissions from producing hydrogen could eclipse those associated with extracting and burning gas when multiplied by the amount of gas required to make an equivalent amount of energy from hydrogen.

   Robert Howarth, a Cornell University professor and co-author of the study, said the research was the first to be published in a peer-reviewed journal to lay bare the “significant lifecycle emissions intensity of blue hydrogen”.

   The paper, which will be published in Energy Science and Engineering, warned that blue hydrogen may be “a distraction” or “something that may delay needed action to truly decarbonise the global energy economy”….”.

    “Biden-backed ‘blue’ hydrogen may pollute more than coal, study finds
    Infrastructure bill includes $8bn to develop ‘clean hydrogen’ but study finds large emissions from production of ‘blue’ hydrogen”

    https://www.theguardian.com/environment/2021/aug/12/clean-fuel-blue-hydrogen-coal-study

    “The large infrastructure bill passed by the US Senate and hailed by Joe Biden as a key tool to tackle the climate crisis includes billions of dollars to support a supposedly clean fuel that is potentially even more polluting than coal, new research has found.

    The $1tn infrastructure package, which passed with bipartisan support on Tuesday, includes $8bn to develop “clean hydrogen” via the creation of four new regional hubs. The White House has said the bill advances Biden’s climate agenda and proponents of hydrogen have touted it as a low-emissions alternative to fuel shipping, trucking, aviation and even home heating.

    But a new study has found surprisingly large emissions from the production of so-called “blue” hydrogen, a variant being enthusiastically pushed by the fossil fuel industry and probably falling under the definition of clean hydrogen in the Senate bill.

    Blue hydrogen involves splitting gas into hydrogen and carbon dioxide and then capturing and storing the CO2 to ensure it doesn’t heat the planet. But this process involves the incidental release of methane, a potent greenhouse gas, and uses a huge amount of energy to separate and then store the carbon dioxide, some of which escapes anyway.

    This means that the production of this hydrogen actually creates 20% more greenhouse gases than coal, commonly regarded the most polluting fossil fuel, when being burned for heat, and 60% more than burning diesel, according to the new paper, published in the Energy Science & Engineering journal.

    “It’s pretty striking, I was surprised at the results,” said Robert Howarth, a scientist at Cornell University who authored the paper alongside Mark Jacobson, a Stanford University researcher. “Blue hydrogen is a nice marketing term that the oil and gas industry is keen to push but it’s far from carbon free. I don’t think we should be spending our funds this way, on these sort of false solutions.”

    The Hydrogen Council, a group that includes the oil companies BP, Total and Shell among its members, has said that hydrogen has a “key role to play in the global energy transition” by replacing more polluting fuels, predicting it will account for 18% of total energy demand by 2050.

    Dozens of gas companies in the US have started producing hydrogen or testing its viability in existing gas pipelines, which some climate campaigners have said is a step towards entrenching fossil fuel infrastructure at a time when the world, as outlined by Monday’s Intergovernmental Panel on Climate Change (IPCC) report, needs to rapidly move to net-zero emissions.”

11. As so often with these schemes, it’s not as easy as it sounds.
    Blending low levels of hydrogen into the natural gas grid should not cause major problems for domestic appliances, aiui (although burners may need regular replacement). However it would cause serious difficulties for gas turbine power plants where the combustion conditions are under very tight tolerances. An HSE report concluded that the hydrogen would have to be removed pre-combustion – assuming that could be done (absorption or membranes maybe?), what happens to the hydrogen then?
    Also the level of blending is unlikely to be uniform across the country and will vary over time (assuming the source is electrolysis powered by “excess” wind generation). That has implications for the maintenance of the calorific value and, maybe, for boiler controls.

    Wrt that article/study decrying blue hydrogen, iirc Howarth, one of the authors, has form as an anti-fracker. Whenever someone bangs the methane drum I wish they could be asked how methane can have much effect outside lab experiments because its absorption spectra are swamped by water vapour which is present at 20,000 times the concentration.

    Speaking of water vapour, burning hydrogen will produce more of it than methane so homes will need better ventilation.

    The paper in question showed that the US could live without hydrocarbons. The below quote was from the National Review in earlier WUWT coverage:

    Rather than accept any of the criticisms Clack and his nearly two dozen co-authors made, Jacobson responded with tirades on Twitter, EcoWatch, and elsewhere. He claimed that his work doesn’t contain a single error, that all of his critics are whores for hydrocarbons, and that, well, dammit, he’s right. Never mind that Jacobson overstated the amount of available hydropower in the U.S. by roughly a factor of ten and claimed that in just three decades or so, we won’t need any gasoline, diesel, or jet fuel because we will all be flying to Vegas in hydrogen-powered 737s.

    One would suspect that Jacobson would be likely to favour electrolysis over steam reforming.

    “EU’s clean hydrogen plan raises dirty doubts
    Methane leaks from non-renewable hydrogen could pollute more than coal and natural gas.”

    https://www.politico.eu/article/eu-clean-hydrogen-plan-doubts/

    “The EU’s hopes of powering its green energy transformation with clean-burning hydrogen could potentially speed up global warming instead, scientists warn.

    A study published Thursday shows that making hydrogen out of natural gas — even when capturing some of the escaping CO2 emissions to make what’s known as “blue hydrogen” — is more polluting than simply burning natural gas directly.

    “The use of blue hydrogen appears difficult to justify on climate grounds,” the study said.

    That’s a problem for the EU. Its Hydrogen Strategy foresees ramping up production of blue hydrogen over the next decade to displace natural gas and also to use in hard-to-electrify sectors like heavy transport and steel and cement production. It’s also banking on cleaner but more expensive green hydrogen, made from water and renewable electricity, eventually becoming available in larger quantities.

    The vast majority of hydrogen produced in the EU is so-called grey hydrogen, made by splitting natural gas into hydrogen and carbon dioxide and allowing the CO2 to escape into the atmosphere. It’s relatively cheap, but has a massive carbon footprint.

    Blue hydrogen is a bit cleaner, but the process requires a great deal of energy, and that’s supplied by burning natural gas, according to Robert Horwath, professor of ecology and environmental biology at Cornell University and co-author of the study published in Energy Science & Engineering.

    Even more energy has to be used to capture the CO2 and “that electricity’s also coming from burning more natural gas without capturing the emissions,” he said….”.

    “Oil companies have used false claims over the cost of producing fossil fuel hydrogen to win over the Treasury and access billions in taxpayer subsidies, according to the outgoing hydrogen lobby boss.

    Chris Jackson quit as the chair of a leading hydrogen industry association earlier this week ahead of a government strategy paper featuring support for “blue hydrogen”, which is derived from fossil gas and produces carbon emissions.

    He told the Guardian he could no longer lead an industry association that includes oil companies backing blue hydrogen projects, because the schemes are “not sustainable” and “make no sense at all”.”

    “The UK’s future blue hydrogen projects include plans for BP to develop a hydrogen plant in Teesside, and Norwegian state oil company Equinor and SSE to build the world’s biggest hydrogen production plant with carbon capture and storage technology near Hull.”

The aim of these companies is to become renewables companies because they believe that our gov’t and others will either ban oil or tax it to death, but that the flow of money for renewables will never be interrupted.

    The bottom line is that however the hydrogen is made, it will have to be subsidised heavily. (Alternatively, it might be possible to tax natural gas to death or simply ban it, but first the boiler switch would have to be made.)

    Hydrogen, being worse in every way than natural gas, is never going to displace it without a large helping hand.

    “UK backs hydrogen CfDs to repeat offshore wind success story”

    The government is proposing using a replica of the CfD scheme that has helped build-out capacity of offshore wind in the UK to more than 10GW while also lowering its cost over the past decade by offering guaranteed ‘strike prices’ for power produced.

    The government said the publication of the document, three months ahead of the UN’s COP26 climate summit in Glasgow, sent out a “strong signal globally” that the UK is to committed to building a thriving hydrogen economy that could deliver hundreds of thousands of green jobs.

    Happened on this while looking for something else. Presumably new green farm machinery could deliver hundreds of thousands of green jobs too. (The return of oversized horses.) The obvious point is that the number of jobs only goes up if a more efficient process is displaced, via gov’t mandate, by a less efficient one.

    The success story referred to is the success of slyly sucking money out of the pockets of people who can’t afford it into the pockets of people who are already rolling in it and with whom in many cases we have very little in common w.r.t. freedom, democracy, old fashioned things like that.

    Government’s plan to use ‘blue’ fossil-fuel hydrogen alongside green version raises concern, say campaigners”

    https://www.theguardian.com/environment/2021/aug/22/uk-switch-to-hydrogen-power-must-not-rely-on-fossil-fuels-warn-campaigners

    “Opting for hydrogen that is made using fossil fuels rather than renewable electricity could create up to 8m tonnes of carbon emissions every year by 2050, according to an analysis of government data.

    The figures show that the use of fossil-fuel hydrogen, or “blue hydrogen”, would create the same carbon emissions each year that more than a million petrol cars would produce, compared with using zero-carbon “green hydrogen”.

    Ministers plan to use both blue and green hydrogen to replace fossil gas in factories, refineries and heating, but new figures show that an over-reliance on blue hydrogen would still lead to millions of tonnes of carbon emissions entering the atmosphere every year.

    Blue hydrogen is extracted from fossil gas in a process that requires carbon capture technology to trap emissions – but this method still fails to capture between 5% and 15% of the CO2. Carbon emissions are also released when the fossil gas is extracted from oil and gas fields.

    Using blue hydrogen exclusively to replace fossil gas would result in between 6m and 8m tonnes of carbon dioxide emissions every year from the late 2020s, or the equivalent of running an average of 1.5m more fossil-fuel cars on the road every year by 2050.”

    Lord Martin Callanan cast doubt on the feasibility of production demands and overall cost”

    https://www.telegraph.co.uk/news/2021/10/05/hydrogen-boiler-revolution-pretty-much-impossible-says-minister/

    “Using hydrogen to replace natural gas as a green alternative in boilers is “pretty much impossible”, a minister has admitted, despite the Government planning major trials over the coming decade….

    “Technology might get us there, there might be some scientific breakthrough. But it’s more likely that it will end up being used by trains and HGVs, for some industrial processes, rather than for home heating.
    “But the official policy is we will see how the market develops and take a view in the mid-part of this decade as to whether it will play a significant role in the home.”…

    ,,,Lord Callanan acknowledged that moving to green heating in homes is “one of the biggest political challenges that we are faced with as a government.”

    “It doesn’t get that much publicity, but it’s something that will cost us an enormous amount of money over the next 15 to 20 years.”

    Lord Callanan said plans to raise the cost of gas would be “nigh on impossible politically” amid the current energy price crunch.

    But he said it would be necessary to rebalance social and green levies, which are currently around 20 per cent of electricity bills and mean running a heat pump is more expensive than running a gas boiler.

    “To persuade people to make the change, we have to provide them with the right incentives. But it’s a difficult policy challenge. Thankfully one for the Treasury and not me,” he said.

    The Government is expected to announce a consultation on rebalancing the levies, with possible options being to move them onto gas or into general taxation.”

22. Cross-pasting a comment on NALOPKT:
    From a report by Jacobs ( Hydrogen supply chain eveidence base; Nov 2018) on the various aspects of adopting hydrogen:

    “Efficiency:The expectation is that H 2 boilers can achieve high efficiencies, similar to those of current natural gas boilers. This would only be confirmed during the required research and development phase of commercialisation.

    Higher burning temperature can lead to NOx formation – performance may be influenced by the NOx specification (low NOx requirements could push down efficiency and may require an exhaust catalyst).

    Lifetime and maintenance: H 2 boilers are expected to achieve 10 15 year target lifetimes (i.e. similar to current natural gas boilers)
    There may be some additional service requirements, hence O&M costs are expected to be higher. Catalytic components (if required) would need to be replaced within 15 year lifetime
    Regular servicing of the appliance may need to be mandatory if components such as exhaust catalysts are needed to ensure performance of the unit is maintained.”

    So, without mitigation via exhaust catalysts, hydrogen boilers will add to NOx pollution. Fitting catalysts will increase costs and maintenance requirements, and efficiency will be lower.
    The report also includes some fairly hair-raising numbers on costs.
    It really is not a happy story.

    “It’s a glorious autumn afternoon and I’m standing on a hillside looking out over Tokyo Bay. Beside me is Takao Saiki, a usually mild-mannered gentleman in his 70s.

    But today Saiki-San is angry.

    “It’s a total joke,” he says, in perfect English. “Just ridiculous!”

    The cause of his distress is a giant construction site blocking our view across the bay – a 1.3-gigawatt coal-fired power station in the making.

    “I don’t understand why we still have to burn coal to generate electricity,” says Saiki-San’s friend, Rikuro Suzuki. “This plant alone will emit more than seven million tonnes of carbon dioxide every year!”

    Suzuki-San’s point is a good one. Shouldn’t Japan be cutting its coal consumption, not increasing it, at a time of great concern about coal’s impact on the climate?

    So why the coal? The answer is the 2011 Fukushima nuclear disaster.

    In 2010 about one third of Japan’s electricity came from nuclear power, and there were plans to build a lot more. But then the 2011 disaster hit, and all Japan’s nuclear power plants were shut down. Ten years later most remain closed – and there is a lot of resistance to restarting them.

    In their place Japan’s gas-fired power stations have been doing a lot of overtime. But, as Britain has found out recently, natural gas is expensive.So, the Japanese government decided to build 22 new coal-fired power stations, to run on cheap coal imported from Australia. Economically it made sense. Environmentally, not so much. Japan is now under intense pressure to stop using coal.

    Instead of closing the old coal plants and switching to renewables, Japan’s answer is to switch to burning hydrogen or ammonia….

    …This brings us to the final, and most important question. Where is the hydrogen to power Japan zero carbon society going to come from?

    The answer is “blue hydrogen”.

    Make hydrogen from water using renewable energy and you get “green hydrogen”. The problem is green hydrogen is really expensive.

    Instead, today most hydrogen is made from natural gas, or even coal. That is cheap but it produces lots of greenhouse gases. However, if you capture those greenhouse gases and bury them in the ground, you are allowed to call it “blue hydrogen”.

    This is exactly what Japan says it is going to do.

    Earlier this year, Japan and Australia opened a joint project in the state of Victoria to turn a type of coal called lignite, or brown coal, into hydrogen. The hydrogen is then liquified to minus 253C, then piped into a specially built ship which carries it to Japan.

    What happens to the greenhouse gases produced at the site? Right now, they go straight up into the atmosphere. But Japan and Australia are promising that, at some point in the future, they will begin capturing the greenhouse gas produced at the Latrobe Valley site and inject it into the sea floor off the coast.

    Climate change campaigners are horrified by this plan. They say the technology to capture and store greenhouse gases is unproven and it will lock Japan into digging up vast quantities of brown coal for decades to come….”.

    A long article, probably worth a read. But with the usual caveats when reading anything about climate change on the BBC. What the BBC omits to mention is that ” Takao Saiki, a usually mild-mannered gentleman in his 70s” is a climate change, anti-coal campaigner:

27. Dr John Constable at the House of Lords’ industry and regulators committee on 14 September 2021. Dr John Constable directs the UK information charity, Renewable Energy Foundation: 

    I have written extensively on hydrogen, and I have what I think is a rational approach to it. Hydrogen is an energy carrier. It is an interesting energy carrier, but it is a difficult gas. It is both fugitive and quite dangerous to handle. However, it is genuinely interesting and could allow us to decarbonise some very difficult areas such as transport, particularly international shipping, as ammonia.

    The key thing is to make the production of hydrogen cheap. That is important for the consumer of the hydrogen but also because making it safe to use in society will not be a cheap activity in itself. It is going to be expensive to make it safe, so the input costs have to be very low. Therefore, the most promising route for hydrogen production is high-temperature nuclear. This was sketched in the 1970s by the physicist and economist Marchetti, known for Marchetti cycles in energy, and was offered to the Japanese. The Japanese government accepted it and are still working on it. It exists within the Japanese machinery as the new Sunshine project.

    It is promising. Will it work? We do not know. It is crucial that the input energy cost is low. Electrolysis from existing nuclear power stations will produce high-cost hydrogen. Electrolysis from renewable energy will produce very high-cost hydrogen. High-temperature nuclear reactors decomposing water thermally, probably in the presence of a catalyst, would in principle produce low-cost hydrogen and might therefore work. If the hydrogen could be low-cost, it would be possible to afford all the safety measures that would be necessary to render it utilisable both in vehicles and in the home. I am open-minded about it and guardedly optimistic.

    https://www.bbc.co.uk/news/uk-england-dorset-60066866

    “A hydrogen fuel project is set to be up and running in Dorset later this year after securing£6.5m of funding.

    Dorset Green H2 is being built at White’s Pitt – a former landfill site off Magna Road in Poole.

    Electricity from solar panels and existing landfill gases will be fed into an electrolyser with water to make green hydrogen – a zero-emission fuel.

    It will be the first of its kind in the region, according to its operator Canford Renewable Energy.

    The hydrogen fuel will be compressed, stored, and sold for use as a carbon-free fuel.

    It is expected to produce enough hydrogen each year to fuel the equivalent of 900,000 miles travelled by lorries.

    It is being funded with £3m from Dorset Local Enterprise Partnership (LEP)’s Growing Places Fund loan scheme, a £1.5m grant from Low Carbon Dorset, along with a £1.7m bank loan and equity funding from Canford Renewable Energy.”

    https://www.bbc.co.uk/news/business-60235709

    “Many people in Britain remain unprepared for the revolution in home heating that the country faces in the next ten to 15 years, a report from MPs has said.

    MPs on the Business, Energy and Industrial Strategy Committee said the government’s approach to decarbonising home heating lacked clear direction.

    Current policies are also not on the scale required, they said.

    However, the report rejected hydrogen as a solution for greener home heating.”

    So, no hydrogen after all? Does that mean we’re wasting a load of money on all the hydrogen experimentation? On top of this:

    “…”In total, we’re investing £6.6bn this parliament to decarbonise our buildings, saving people money on their bills and slashing pollution in the process,” a BEIS spokesperson said….

    …BEIS said the government’s existing plans would incentivise people to install low-carbon heating systems “in a simple, fair and cheap way” and included £5,000 grants for heat pumps…”.

    But back to hydrogen:

    “However, the cross-party committee poured cold water on suggestions that hydrogen could play a major role in home heating.

    Mr Jones told BBC News: “We were not convinced that hydrogen was proven to be a front-running, viable technology.

    “I understand why trades unions are enthusiastic about hydrogen because it preserves jobs – but many workers will need to transition to heat pumps.

    Concerns around hydrogen included “supply, distribution, changes to the network, changes in the home with safety work around pipes and valves – so many reasons we’re not convinced,” he said.

    Mr Jones’ comments were attacked by Mike Foster from the trade body Energy and Utilities Alliance.

    “Comments in the report [about hydrogen] are factually untrue and others deliberately misinterpret government plans,” Mr Foster said.

    Another industry lobby group, Electrify Heat, said it was clear that heat pumps would provide heat for most homes and that hydrogen would have a very small role.”

    Dear, oh dear, oh dear. Rushing down the net zero road, but with no idea where it is going. Except that it’s going to cost the taxpayer a lot of money, and some people are making a lot of money out of it.

    https://www.bbc.co.uk/news/business-60241966

    “An ambitious target of using hydrogen to partly power homes in the UK within three years has been set by the National Grid, the BBC has learned. On the east coast of Scotland, a small neighbourhood is playing a key role in this energy revolution.

    From next year, about 300 homes in Buckhaven, and Methil, in the area of Levenmouth, will be powered by green hydrogen gas in a project called H100. Customers will be offered free hydrogen-ready boilers and cookers in the scheme, which will initially last five and a half years.

    For the first time in its history, the National Grid (NG) plans to use something other than natural gas in its distribution network and start blending hydrogen with natural gas in the next three years.

    Yet, standing in the former Fife coal mining village of Buckhaven as a cold wind howls round buildings made of local grey stone, it’s hard to imagine this is the centre of a groundbreaking experiment working towards the NG’s ambitions.

    But as soon as you walk towards Buckhaven waterfront, it’s impossible to ignore. A 200-metre wind turbine, astonishing in its size and generating green energy, stands just off the coast, making a loud swoosh every couple of seconds, as the wind is picked up and thrown into the sea.

    The region has a long, proud history of energy production from its mines, but now the focus is on more environmentally friendly natural resources.

    The huge wind turbine will generate electricity to power an electrolyser, which turns water into hydrogen gas and oxygen. The hydrogen will then be stored in pressurised secure tanks, before being pumped into people’s homes.

    The £28m project, partly funded by the Office of Gas and Electricity Markets (OFGEM), has the capability to be expanded to 1,000 homes from the same turbine.”

    “The war in Ukraine has upended Germany’s energy policy.

    The nation currently buys around 25% of its oil and 40% of its gas from Russia, contributing billions of euros a year to Moscow’s finances.

    Germany is moving “as fast as possible” to end that relationship, but it will take time, the country’s finance minister recently said.

    To help achieve that goal, Veronika Grimm – an economics professor at the University of Erlangen-Nuremberg – wants Germany to “ramp up” its use of hydrogen.

    Hydrogen can store vast amounts of energy, replace natural gas in industrial processes, and power fuel cells in trucks, trains, ships or planes that emit nothing but water vapour.

    Ms Grimm’s enthusiasm is gaining traction, according to the International Energy Agency (IEA), an energy research group, dozens of countries have published national hydrogen strategies, or are about to.

    It says it wants to help the transport industry adapt to a “post-fossil fuel future”.

    To that end, it developed a fuel cell to top up electric battery-powered trucks, giving them a longer range while reducing the size of the electric battery needed.

    The company – which has displayed the vehicle at the Road Transport Expo in Stoneleigh, Warwickshire – said hydrogen had been used safely in buses and other vehicles in 20 countries over a number of years.”

    As for “up to 310 miles”, Tevva’s own website says this:

    “Range on ANY EV is not constant, but 275kWh provides at least 450km range on the majority of days and at least 300km in the most adverse of conditions.”

    The energy company has drawn up proposals for a 100megawatt plant at the Suffolk port which will provide enough fuel to power 1300 hydrogen trucks from 2026.

    The company, owned by €63bn Spanish utilities giant Iberdrola, said demand for the green fuel had stepped up since petrol and diesel prices began to soar last year, emboldening the firm to invest.

    It has submitted an application to the government’s Net Zero Hydrogen Fund, which provides state backing to develop low-carbon hydrogen projects for the next three years. ScottishPower estimated the whole project could cost between £100m and £150m.”

    Of course, the crucial piece of missing information is how much of the £150M cost will end up being paid for by the UK taxpayer. Here we are, according to the Guardian (and I am inclined to agree) in the midst of an energy crisis and a cost-of-living crisis, yet there never seems to be a shortage of taxpayer money to give away to foreign energy companies for projects with no guarantee of success and which (certainly in the short term, and probably in the long term) will do nothing to improve the UK’s energy security or costs.

Now, the town on Scotland’s east coast is flirting with another era in the energy industry – but it doesn’t appear to be going to plan.

H100 hopes to address the need for alternative energy sources to gas, not least as heating accounts for about 37% of all UK carbon emissions.

    A new study has cast doubt on government claims that hydrogen could be used to heat homes and so cut greenhouse gas emissions.

    The report, published in the journal Joule, analysed more than 30 studies that looked at hydrogen and heating.

    All those studies found that hydrogen was much less efficient and more costly than alternatives like heat pumps

    Last week the Business Secretary Jacob Rees-Mogg told the Commons that hydrogen was a “silver bullet”….

    …”Using hydrogen for heating may sound attractive at first glance,” says Jan Rosenow the report’s author and Europe Director at the energy think-tank the Regulatory Assistance Project.

    “However, all of the independent research on this topic comes to the same conclusion: heating with hydrogen is a lot less efficient and more expensive than alternatives such as heat pumps, district heating and solar thermal,” he said….

    Or, as he might have said, we could just leave our existing gas infrastructure in place – it would be a lot cheaper.

    …”In the UK, heating homes with green hydrogen would use approximately six times more renewable electricity than heat pumps,” says David Cebon of the Hydrogen Science Coalition and Professor of Mechanical Engineering in Cambridge University.

    “We do not have the time or resources to waste further investigating hydrogen’s role in home heating, especially when the well-known laws of thermodynamics determine the answer,” he said.

    The report said there was a risk that discussion of hydrogen for heating in the future led to a delay in the deployment of clean heating technologies that are already available today.

    https://www.theguardian.com/environment/2022/sep/27/hydrogen-is-unsuitable-for-home-heating-review-concludes

    Fiona Harvey Environment correspondent
    Tue 27 Sep 2022 16.00 BST
    Hydrogen is unsuitable for use in home heating, and likely to remain so, despite the hopes of the UK government and plumbing industry, a comprehensive review of scientific papers has concluded.

    Hydrogen lobbyists are out in force at the Labour party conference this week, sponsoring several events in Liverpool, and will be plentiful at the Conservative party conference that begins this weekend.

    They are hoping to persuade the UK government to push ahead with a mooted large-scale rollout of hydrogen for home heating, as a replacement for the gas used to heat the vast majority of British homes. Hydrogen proponents say it would avoid households having to replace gas boilers with heat pumps, the other main contender for low-carbon home heating.

    But researchers reviewed 32 studies of hydrogen and concluded that it was unlikely to play a major role in home heating, either as a full replacement for fossil fuel gas heating, or as a blend with natural gas.

    Jan Rosenow, Europe director at the Regulatory Assistance Project, an energy thinktank, and co-author of the study, said there were too many technical difficulties to overcome to make hydrogen a viable and economic low-carbon heating fuel.

    “Using hydrogen for heating may sound attractive at first glance. However, all of the independent research on this topic comes to the same conclusion: heating with hydrogen is a lot less efficient and more expensive than alternatives such as heat pumps, district heating and solar thermal,” he said.

    The study, published on Tuesday in the peer-review scientific journal Joule, is the third major blow in the past week to proponents of hydrogen for home heating. Earlier this week, a separate study by the analyst company Cornwall Insight concluded that hydrogen would be close to twice as expensive for home heating as using gas alone. Last week, the Guardian revealed problems with a hydrogen pilot project in Scotland.

    Rosenow told the Guardian hydrogen was not the alternative to heat pumps that lobbyists were claiming. “For policymakers, hydrogen for heating appears attractive because it seems easy: just replace fossil gas with hydrogen with no impact on households. The reality is that significant technical alterations are needed including the pipework in homes and that it will cost people a lot of money to keep warm.”

    Michael Liebreich, the founder of Bloomberg New Energy Finance and chairman of Liebreich Associates, said: “This is a timely paper, showing that no serious analysis has hydrogen playing more than a marginal role in the future of space heating. We need to get Europe’s heating systems off natural gas, and we need to do it without further delay. It’s time to stop the fight: the judges are unanimous and the winners are district heating, heat pumps and electrification.”…

    The political offensive was emblematic of the Bamford dynasty’s close political ties and the hydrogen industry’s eagerness to foster goodwill in Westminster. Companies including Cadent, National Grid, Centrica and boiler maker Worcester Bosch joined Bamford’s companies Ryze Hydrogen and Wrightbus in trying to convince Labour and Conservative MPs that hydrogen, the emissionless, highly combustible gas, can be a valuable weapon in the fight against the climate crisis….

    …Since Jo Bamford bought bankrupt London bus maker Wrightbus in 2019, the grandson of JCB founder Joseph Cyril Bamford has bet big on hydrogen. It has won several taxpayer-funded contracts for green transport, including an £11.2m deal to develop hydrogen fuel cell technology in Northern Ireland. Last year, he launched HyCap, a £1bn investment fund designed to back hydrogen specialists from producers to fuelling stations and transport firms.

    Bamford is far from alone in cultivating cordial relations with the government. There are at least 120 paid lobbyists for hydrogen operating in parliament at present, according to estimates from the MCS Charitable Foundation. In the EU, a vast network of fossil fuel companies, trade associations and other interested parties are putting the case for hydrogen.

    Their goals are disparate, from gaining support and subsidies for decarbonising energy-intensive industries to convincing authorities to switch to heating homes with hydrogen boilers. Hydrogen is seen as a transition fuel to a future powered by renewables such as wind and solar, allowing existing gas pipes to be used to pump the gas.

    But the march of the hydrogen lobby has thrown up many questions – how much will it all cost, are there more affordable ways of getting to net zero, and are vested interests such as the oil industry simply trying to stave off extinction?

    “Green” hydrogen is produced by splitting water using electricity from renewables, with minimal emissions. However, detractors argue that creating green hydrogen for home heating is six times less energy efficient than using heat pumps powered by electricity. Meanwhile, “blue” methods to produce the gas from fossil fuels require the carbon dioxide released to be captured and stored to prevent emissions. However, this relies on the success of the unproven carbon-capture and storage industry, which is in its infancy. …

    wonder where x6 statement comes from? anyway what about –

    “A heat pump works a bit like a refrigerator in reverse; instead of keeping your food cool, it’s warming your home using a refrigerant, which can evaporate into gas and condense into liquid.
    The source of heat – air outside or warmth from the ground – is blown or pumped over the heat exchange surface of the exterior part of the heat pump.
    This heat (although cold in comparison to a centrally-heated home) is warm enough to cause the special refrigerant liquid to evaporate and turn into a gas.
    This gas then moves through a compressor, which increases the pressure and so causes its temperature to rise.The gas (now heated) is passed over the internal heat exchange surface. This heat can then be either blown around the interior or transferred into a central heating or hot water system.
    The gas falls in temperature as the heat is transferred into the home and it subsequently returns to a liquid state.
    The cycle of reverse refrigeration repeats until your home or business reaches the required temperature setting on your thermostat.
    As the ground and air outside always contain some warmth, a heat pump can supply heat to a house even when it’s cold outside. For heat pumps to work at their best, it’s also important that good energy efficiency is installed in the home, such as effective insulation.”

    https://www.politico.eu/article/go-big-or-go-green-the-eus-massively-expanding-hydrogen-bet/

    Two back-to-back crises have pushed Europe to bet increasing amounts of cash on a hydrogen revolution to meet industrial ambitions and reduce carbon emissions. But its promise to keep its economy growing while meeting 2050 climate targets looks increasingly tenuous.

    For the hydrogen industry, it’s a subsidy boom. European Commission President Ursula von der Leyen is promising a €3 billion investment vehicle, dubbed a hydrogen bank, to “help guarantee the purchase of hydrogen” by spurring demand using cash from the EU Innovation Fund.

    That comes on top of more than €13 billion in state aid approvals for national and cross-border projects so far: €5.4 billion for Hy2Tech, a cross-border initiative to perfect the technology; €5.2 billion for Hy2Use, aimed at applications in hard-to-decarbonize sectors such as steel, cement and glass; more than €2 billion for German projects in steel, chemicals and production abroad; €220 million for a Spanish plant, and €194 million for a Romanian plant.

    Two more cross-border state aid hydrogen schemes — dubbed Important Projects of Common European Interest — are also in the works, to focus on infrastructure and mobility, though amounts have yet to be released….

    …Before May 2020, there was no such thing as a standalone EU hydrogen strategy. Hydrogen was mentioned only as a complement to rolling out renewable energy and better power grid connections in the Commission’s Green Deal plans.

    Only when the coronavirus crisis threatened to derail those green dreams in early 2020, did the Commission move swiftly to prioritize hydrogen, according to Jorgo Chatzimarkakis, CEO of industry lobby Hydrogen Europe.

    “The crisis broke out, there was a pressure on policymakers to deliver right away, to mobilize the funds needed for a green recovery,” he recalled. “We were very, very fast in reacting to what the Commission needed … we came back to them in May with a concrete plan.”

    That industry road map called for 40 gigawatts (GW) of electrolytic capacity to be built across the EU by 2030, to use renewable electricity to jolt hydrogen out of water. A further 40 GW of production capacity would also be built abroad with the hydrogen then imported by the EU.

    Those plans had a €430 billion price tag over a decade….

    Among other things it mentions is this (which I confess I previously knew nothing about):

    “Hydrogen Business Model and Net Zero Hydrogen Fund: Electrolytic Allocation Round 2022”

    So I took a look:

    https://www.gov.uk/government/publications/hydrogen-business-model-and-net-zero-hydrogen-fund-electrolytic-allocation-round-2022

    Guess what?

    Hydrogen will play a vital role in delivering the UK’s commitment to reach net zero by 2050.

    The UK is aiming to develop up to 10GW of low carbon hydrogen generation by 2030, subject to affordability and value for money (VfM), with the intention that at least half of this will be from electrolytic hydrogen, drawing on the scale up of UK offshore wind, other renewables, and new nuclear.

    The Energy Security Strategy set out our ambition to support up to 1GW of electrolytic hydrogen being in construction or operational by 2025. We aim to run yearly electrolytic allocation rounds for the Hydrogen Business Model (HBM) and move to price-competitive allocations by 2025 as soon as market conditions and legislation allow.

    This guidance details our proposed approach for the first joint Hydrogen Business Model and Net Zero Hydrogen Fund allocation round. We hope to support at least 250MW via the first allocation round, although we retain the right to allocate less if we do not see sufficient projects coming forward that meet our eligibility criteria and present VfM to government.

    For the 2022 HBM / NZHF Electrolytic Allocation Round, we propose that projects can apply for HBM revenue support only, or they can apply for joint HBM revenue support and CAPEX support through the Net Zero Hydrogen Fund (NZHF).

    Something else for “net zero” that sees the Government’s hand in the taxpayer’s pocket.

    In Whitby, just outside Ellesmere Port, residents wait to hear whether their village will be chosen”

    https://www.theguardian.com/environment/2022/nov/21/no-choice-hydrogen-heating-pilot-whitby-ellesmere-port-lab-rats

    On the site of an old leisure centre, a U-shaped trio of temporary offices sit alongside a neat lawn and fledgling shrubs. Named the “hydrogen experience centre”, this unassuming place is at the heart of a testy tussle that could have implications for how homes across the country are heated.

    The site, in the village of Whitby, just outside Ellesmere Port on the south bank of the Mersey, could become the UK’s first “hydrogen village”. It is being analysed, along with Redcar in the north-east, for potential conversion to 100% hydrogen heating, using the existing gas network and new appliances to update up to 2,000 properties…

    …A decision on whether to use hydrogen in the gas network at a wider scale is due in 2026. It will come a year after a ban on gas boilers in new homes comes into force in 2025, although uncertainty remains over the timeframe for the phase-out of natural gas in existing homes.

    However, there are concerns about the practicality of using hydrogen and the resulting cost to residents. Some people fear they are at risk of becoming unwilling “lab rats” for a technology that never takes off…

    …The proposal for Whitby to become a hydrogen test site – which is being presented by Cheshire West and Chester council, Cadent and British Gas – would give residents the choice of hydrogen or electric alternatives. The cost of new appliances and installation would be covered and the hydrogen would be subsidised to cost the same as natural gas for two years.

    But those who opt out of the hydrogen trial would not be able to stay on gas. Cadent has said it would consider subsidising their electricity – which is typically more expensive than using gas – but it is yet to commit to this. At the end of the pilot, if the decision is made to revert to natural gas, Cadent will cover the costs.

    “We’re being forced to take either hydrogen or an electric alternative if the pilot proceeds. There is no choice not to be part of it,” says John Roach, a retired housing manager who has been convening residents to debate the project.

    “My main concerns are financial: they’re subsidising the hydrogen for two years, but not beyond that. Local boiler engineers have told us they’re not going to bother getting trained up for a small area. So boiler and appliance maintenance and repair is going to be more expensive or hard to find. We’ll be trapped. If we’re the only game in town, how easy will it be to get a replacement?”

    Kate Grannell, another resident, says: “No one is questioning that we need to move away from natural gas but what many of us are saying is, experts know that hydrogen is not the long-term replacement for home heating. I will not be letting the emperor sell me his new clothes.”…

    Devoid of bodywork, with its intricate wiring and pipework exposed, it sits securely fastened to a sturdy test rig, while engineers cluster around an array of screens in the control room, a safe distance away.

    The tests are being carried out by Rolls-Royce, after development work in Derby and in partnership with the airline easyJet….

    Keep reading…

    …The advantage of hydrogen over batteries is that it provides much more power per kilogram. Batteries are simply too heavy to power larger planes.

    Yet hydrogen aviation remains a very long way off. The tests carried out so far have simply shown that a jet engine using hydrogen can be started up and run at low speed.

    But to go from there to building a wholly new engine, capable of powering a passenger aircraft safely will take a great deal more research – and significant investment.

    The aircraft themselves will also need to be redesigned. Hydrogen, even in liquid form, takes up about four times as much space as the kerosene required to fly the same distance.

    To make it into a liquid in the first place, it needs to be cooled to -253C. Then, before being burned, it must be turned back into a gas.

    “There’s a big change from the aircraft point of view,” says Alan Newby at Rolls-Royce.

    “They’re going to have to have a tank containing the hydrogen. You’ve got to keep it at this really, really cold temperature.

    “Then there’s the issue of how you feed it through to the engine as well.”

    The other key question is where the hydrogen itself comes from, because that will have a dramatic impact on the environmental benefits it can provide…

    The energy company SSE has begun work to develop an underground cavern in east Yorkshire to store hydrogen, aiming to stockpile the renewable source of power for when the freezing, windless conditions experienced in the last week occur in future.

    The project will produce hydrogen using renewable energy in a 35-megawatt electrolyser which will be stored in a cavern the size of St Paul’s Cathedral located a mile deep at an existing SSE site in Aldbrough on the Yorkshire coast.

    The hydrogen will be used to fire a turbine which can export power to the grid when demand is high.

    SSE hopes the “pathfinder” project, which could cost more than £100m, will demonstrate the technology before bigger projects in the area which would require larger pipelines and infrastructure. The company hopes to receive government money for the project through a fund set up to support low-carbon hydrogen projects.

    “I wake up in the night thinking about it,” Maria Morgan says. “We’re guinea pigs.”

    Maria is on the front line of the UK’s efforts to cut greenhouse gas emissions and combat climate change.

    Her house in Whitby in Ellesmere Port, north-west England, is one of 2,000 homes earmarked to have its supply of natural gas turned off.

    If the Whitby proposal is approved, pure hydrogen will flow through its pipes from 2025. Hydrogen’s advantage is that unlike natural gas, it doesn’t produce the climate-warming gas CO2 when burnt….

    …But is hydrogen safe? The government and gas companies say it can be, even though hydrogen is both more leaky and combustible than natural gas.

    It’s also not clear how green the village will actually be. Though hydrogen can be made from water using renewable energy, more than 99% of the world’s supply is currently made from fossil fuels, creating CO2 emissions.

    While some Whitby residents welcome the proposal, others feel they’re being forced to take part in a dangerous experiment…

    …If the trial goes ahead, there will be no more natural gas in the Whitby “hydrogen village” area. Residents will have to choose between converting their homes to hydrogen or going electric with a heat pump, with all the new appliances provided free of charge.

    Both the gas companies and the government say residents are worrying needlessly about safety. They say that though hydrogen is more explosive, additional measures will be in place making the risk similar to that of natural gas.

    That doesn’t wash with Professor Tom Baxter, an expert in hydrogen at the University of Strathclyde.

    “Would you buy a car from a salesman who said, ‘This car will crash more often but because of the safety features, we will be just as safe?” he asks. “You wouldn’t do it.”..

    …Hydrogen is certainly cleaner and greener at the instant it burns. But how the hydrogen is made is critical, given how little is currently produced using renewable energy.

    Using hydrogen made from renewable electricity to heat buildings is also much less efficient than simply using the electricity.

    Dr Jan Rosenow, an energy expert and director of European programmes at the Regulatory Assistance Project, told the BBC that heating a home with this “green” hydrogen uses five or six times more electricity (to produce the hydrogen) than using the same renewable electricity to drive a heat pump.

    https://www.theguardian.com/environment/2023/mar/07/hydrogen-clean-fuel-climate-crisis-explainer

    Is there any role for hydrogen in a decarbonised future?
    Yes, but a limited one – given that it takes more energy to produce, store and transport hydrogen than it provides when converted into useful energy, so using anything but new renewable sources (true green hydrogen) will require burning more fossil fuels.

    According to the hydrogen merit ladder devised by Michael Liebreich, host of the Cleaning Up podcast, swapping clean hydrogen for the fossil fuel-based grey and brown stuff currently used for synthetic fertilisers, petrochemicals and steel is a no-brainer. The carbon footprint of global hydrogen production today is equivalent to Germany’s annual greenhouse gas emissions, so the sooner we swap to green hydrogen (created from new renewables) the better. This could also be useful for some transportation, such as long-haul flights and heavy machinery, and maybe to store surplus wind and solar energy – though none are slam dunks for hydrogen as there are alternative technologies vying for these markets, said Liebreich.

    But for most forms of transport (cars, bikes, buses and trains) and heating there are already safer, cleaner and cheaper technologies such as battery-run electric vehicles and heat pumps, so there’s little or no merit in investing time or money with hydrogen. Howarth said: “Renewable electricity is a scarce resource. Direct electrification and batteries offer so much more, and much more quickly. It’s a huge distraction and waste of resources to even be talking about heating homes and passenger vehicles with hydrogen.”

    Human rights? Who are you kidding? Net zero has to save the planet, don’t you know!

76. “Blending hydrogen into gas heating ‘could add almost £200’ to UK bills
    Campaigners say potential energy plan would leave consumers bearing cost of building hydrogen economy”

    https://www.theguardian.com/environment/2023/apr/11/blending-hydrogen-gas-heating-add-almost-200-uk-bills

    Blending hydrogen into the UK’s gas heating systems could raise consumer bills by almost £200 for an average household, analysis suggests.

    The blending of natural gas with about 20% hydrogen, for use in home heating systems, is one of the key recommendations by the government’s hydrogen champion, Jane Toogood, in a report to ministers on how to produce and use hydrogen in the UK.

    But a group of green campaigners, thinktanks and energy companies have written to the energy secretary, Grant Shapps, urging him to reconsider. Analysis by the thinktank E3G shows hydrogen blending could increase the average household’s heating bill by about £192 a year.

    In the letter, seen by the Guardian, the groups warn that blending hydrogen into the gas supply would require consumers to use more gas, as hydrogen provides less energy than fossil gas when used in this way. “We disagree with the report’s recommendation to stimulate demand for hydrogen through blending and heating,” wrote the groups, led by E3G.

    “This puts the early costs of building the hydrogen economy on the shoulders of consumers, who will bear the costs of higher energy bills and costs of conversion – on top of the proposed ‘hydrogen levy’ set out in the energy bill. As hydrogen is more expensive than the gas currently used to heat most UK homes, a 20% blend can only raise consumer prices. Raising energy bills during a cost of living crisis is the wrong way to develop industrial demand for hydrogen.”

    The government is expected to decide this year whether to press ahead with plans for the blending of hydrogen into the UK’s natural gas networks, which could happen as soon as 2025. Ministers are also considering a hydrogen levy on bills to fund its development.

77. Quite a bunch of sceptics at the Guardian these days.

78. Arguably a puff piece for hydrogen:

    “Scotland’s hydrogen opportunity”

    https://www.bbc.co.uk/news/uk-scotland-scotland-business-65561904

    However, Douglas Fraser can generally be relied on to offer a balanced write-up, and so it proves. He concludes:

    …Transport could use it as well, but the expectation that it could be of use in cars is waning. Batteries are seen as making more sense in terms of anticipated cost, as they do even for urban buses.

    Passenger trains have spearheaded the prototype deployment of hydrogen, but don’t look like becoming a big customer, where the infrastructure of electricity can power them instead.

    Instead, it looks more like heavy transport being a heavy user of hydrogen, including trucks and shipping, plus some agriculture that reaches beyond the electricity grid, or where the need for refuelling is a constraint.

    The other area where hydrogen was seen as the answer to a huge decarbonising challenge was in home heating. That is looking less likely. Even non-domestic heating is seen in these Scottish Enterprise reports as having a relatively low potential, including the use of hydrogen to fire up Scotland’s crematoria.

    Hydrogen as an energy source has its doubters and critics, and it remains a heated debate. The green variety, derived from water using renewable energy, is welcomed. But the blue variety, from cracking natural gas, much less so.

    It would require a lot of carbon capture and storage, putting a lot more emphasis on the ‘net’ – the mitigation of burning fossil fuels – than on the ‘zero’.

79. Timera Energy have explained how the EU is classifying “green” hydrogen and the implications for the producers in terms of power sources, etc.:

    It shows, once again, that ideas which appear simple in concept – such as using (excess) renewable electricity to generate hydrogen – are anything but straightforward in detail.
