cleantechnica.com 24-11-2023 The Odyssey Of The Hydrogen Fleet: A Tragicomedy In Six Acts – by Michael Barnard
…The pattern never changes. The fleet owners never look up to see how this played out elsewhere. The do-gooder apparatchiks never bother to engage their higher brain functions, use spreadsheets with anything approaching rigor or ask what has happened to other hydrogen programs. The fleet owners never look up from their little patches of road and realize that their conditions are exactly the same as everybody else’s. I’d use a Matrix analogy but the red-pillers have ruined that one. Here are some examples of this playing out. Let’s start in the country side of France, in the commune of Pau. It’s a pleasant place of rolling hills with about 70,000 inhabitants. The government provided scads of cash, €9 of the €15 million for the scheme with its twelve buses. Note that it’s more than a million per bus, about three times the cost of a Yutong electric bus. The commune’s transit firm bought hydrogen buses and pumps. They managed to source hydrogen that was 80% green. They had an incredibly difficult time keeping the complex hydrogen drive trains running. Then the government stopped paying for the hydrogen. The commune ditched the buses and pivoted to electric buses.
Let’s head over to Germany, to Lower Saxony. The local light rail operator, LVNG, got €93 million from the government to buy 14 hydrogen trains which went into operation in 2022. They can’t afford to keep them running without lots of governmental money, so a year later, they’ve made it clear that they aren’t buying any more and will be buying only electric trains from now on. Of course, they could have looked at the nearby state of Baden-Württemberg which at the beginning of 2022 made it clear that hydrogen trains were three times more expensive than grid-tied and battery trains. But no, looking up and asking experts isn’t what many of these parochial fleet operators do. Next, a trip next door to Austria. Ikea has just entered Act 3, receiving €4.8 million to purchase a mere five mid-sized delivery vans because their supplier makes crappy battery electric vans with inadequate range in a country of with 22,000 public electric vehicle chargers and only seven hydrogen refueling stations. Compare that almost a million euros with the comparable range and load BrightDrop ZEVO 600’s MSRP of $85,000, well under a tenth. I predict that the drivers will love driving mostly between the widely spread refueling stations and delivering almost no parcels to cranky customers while continuing to get paid. For a year or perhaps two. Then Ikea will realize that Quantron makes terrible electric vans and force them to improve or find a supplier like BrightDrop that is technically competent with real delivery vans.
This isn’t just a European thing, of course. Next let’s go look at India. It’s a fascinating case study which made the hydrogen chorus chant madrigals of joy very badly. The country bought some hydrogen locomotives. For a tiny subset of their tracks that were used occasionally for tourism on very old routes through a scenic area. Meanwhile, the country has electrified over 85% of their heavy rail and is heading for 100% by 2025. I predict the tiny tourist trains will be switched into an unused sidetrack within a couple of years of first hitting the rails, theoretically in 2024, replaced with battery electric trains. But for the full blown Las Vegas-scale megaproduction version of this show, we have to look at California. A couple of decades ago, battery electric vehicles really weren’t a thing but the hydrogen economy was a massive hype bubble. As a reminder, Plug Power, Ballard and FuelCell Energy all had their massive stock overvaluations in 2000. Rifkin’s tome of nonsense, The Hydrogen Economy, came out in 2002. A lot of otherwise intelligent people thought hydrogen for transportation and a lot of other things it’s ill-suited for was the only option….
cnn.com 29-10-2023 They went hunting for fossil fuels. They found hydrogen – By Laura Paddison,
When two scientists went looking for fossil fuels beneath the ground of northeastern France, they did not expect to discover something which could supercharge the effort to tackle the climate crisis. Jacques Pironon and Phillipe De Donato, both directors of research at France’s National Centre of Scientific Research, were assessing the amount of methane in the subsoils of the Lorraine mining basin using a “world first” specialized probe, able to analyze gases dissolved in the water of rock formations deep underground. A couple of hundred meters down, the probe found low concentrations of hydrogen. “This was not a real surprise for us,” Pironon told CNN; it’s common to find small amounts near the surface of a borehole. But as the probe went deeper, the concentration ticked up. At 1,100 meters down it was 14%, at 1,250 meters it was 20%.

bbc.co.uk 31-7-2023 Carbon capture: What is it and how does it fight climate change? By Jonah Fisher
…The technology has been around for decades. It’s mainly been used in industries where captured CO2 can be reused, for example to force out oil and gas from underground reserves. There are no such plans to use the CO2 from the new proposed power stations. The cost of a new gas power station, providing electricity for nearly a million homes, is around £350m. Catherine Raw of energy company SSE told the BBC that building a similar sized gas power station with carbon capture would roughly double the cost. The hope is that the price might fall over time. The cost of renewable energy for example has plummeted in the last decade.
There are those who see carbon capture as too expensive and believe the money would be better spent on renewables and power storage (like batteries). “These power stations look like another excuse for the government to show preference to their friends in the oil and gas industry, making energy more expensive to everyone else’s disadvantage,” says Dr Doug Parr of campaign group Greenpeace UK.
In September 2022 there were just 30 carbon capture facilities in the world, according to a report from the Global CCS Institute. Almost all of these are attached to industrial plants carrying out activities such as natural gas processing or fertiliser production. Once built, it is hoped other industries would use the UK power station’s pipeline to store CO2 under the North Sea….
theguardian.com 24-3-2023 Forget geoengineering. We need to stop burning fossil fuels. Right now – Pie-in-the-sky fantasies of carbon capture and geoengineering are a way for decision-makers to delay taking real action – by Rebecca Solnit
…”…They come up with endlessly creative ways to continue extracting and using fossil fuel. One of their favorites is to make commitments that can be punted off to the future, which is why one recent climate slogan is “delay is the new denial”. Another is to pretend that they are somehow still looking for a good solution and once they find it they will be very happy to use it. A holy grail, a hail Mary pass, a magic bullet, a miracle cure – or just a distracting tennis ball that too many journalists, like golden retrievers, are happy to chase.
That was clear when Lawrence Livermore National Laboratory announced its nuclear-weapons-related fusion breakthrough last winter, which the Bulletin of the Atomic Physicists noted had “at best, a distant and tangential connection to power production”. But many news stories latched on to it as if we were waiting for some miraculous solution when the solutions already exist and just need to be scaled up. It was as if they were selling us a dream of a lifeboat eventually reaching our shipwreck when viable lifeboats are all around us.
Dr Jonathan Foley, who heads Project Drawdown, joked that “fusion is here now. Look up in the sky.” The sun gives us far more energy than we can ever possibly use, now that solar panels let us convert some of that to electricity.
Among the worst of the excuses for not doing the one thing we must do is carbon capture, which has absolutely not worked at any scale that means anything and shows no sign of so doing on a meaningful scale in the near future. But while it is dangled as a possibility, it creates a justification to keep burning fossil fuel. So does geoengineering, which along with posing many kinds of disruptions is a way to compensate for continued emissions from burning things rather than stop burning them. These centralized hi-tech solutions seem to appeal to technocrats and beneficiaries of large corporations and centralized power, who perhaps don’t like or don’t comprehend the decentralization of power coming from sun and wind.
The decision-makers here often seem like a patient who, when told by a doctor to stop doing something (smoking, say, or maybe mainlining drain cleaner), tries to bargain. All the vitamins and wheatgrass juice on Earth won’t make toxic waste into something nontoxic, and all these excuses and delays and workarounds and nonexistent solutions don’t replace what the IPCC tells us: stop burning fossil fuel.
Move fast. Step it up. Now. Which brings us back to something that climate organizers have told us for a long time and the new report brings home. We know what to do, and we have the solutions we need to do it, so the biggest problems are political. They’re banks, politicians, financiers and the fossil fuel industry itself. We don’t need any magic technology to defeat them, just massive civil society willpower set in motion.
bbc.co.uk 13-3-2023 Optimism grows for Acorn Project carbon capture scheme – By Kevin Keane
Optimism is growing that Scotland’s first carbon capture and storage facility is finally about to be given the go-ahead.
The Acorn Project at the St Fergus gas terminal in Aberdeenshire would pipe harmful greenhouse gas emissions under the North Sea. …
… Redundant gas pipelines from the north east to the refinery at Grangemouth would be put into reverse to carry the CO2 back north. Energy firm SSE Thermal has said it wants to build a new power station at Peterhead which would incorporate CCS. The existing terminal at St Fergus would be used to turn natural gas into so-called blue hydrogen with the carbon dioxide being pumped back offshore. There is even a proposal for direct air capture which would suck CO2 out of the air for storage.
However some environmentalists are opposed to the technology which they feel is a “dangerous distraction” from the urgent need to cut our emissions. Friends of the Earth Scotland has long been vocal in its view that the money would be better spent on delivering a “just transition” away from fossil fuels.
Last week, Westminster’s Scottish Affairs Committee published the findings of its inquiry into CCS in Scotland. It said the Acorn Project could hold the key to the technology being rolled out at scale across the UK and called on Jeremy Hunt to provide backing in his budget.
BBC Scotland understands that the company behind the Scottish Cluster, Storegga, has not been given any more details about the Chancellor’s forthcoming budget announcement. However the company is believed to be optimistic that it would be good news.

nature.com 9-3-2023 Diverse carbon dioxide removal approaches could reduce impacts on the energy–water–land system – by Jay Fuhrman, Candelaria Bergero, Maridee Weber, Seth Monteith, Frances M. Wang, Andres F. Clarens, Scott C. Doney, William Shobe & Haewon McJeon
Abstract – Carbon dioxide removal (CDR) is a critical tool in all plans to limit warming to below 1.5 °C, but only a few CDR pathways have been incorporated into integrated assessment models that international climate policy deliberations rely on. A more diverse set of CDR approaches could have important benefits and costs for energy–water–land systems. Here we use an integrated assessment model to assess a complete suite of CDR approaches including bioenergy with carbon capture and storage, afforestation, direct air capture with carbon storage, enhanced weathering, biochar and direct ocean capture with carbon storage. CDR provided by each approach spans three orders of magnitude, with deployment and associated impacts varying between regions. Total removals reach approximately 10 GtCO2 yr−1 globally, largely to offset residual CO2 and non-CO2 emissions, which remain costly to avoid even under scenarios specifically designed to reduce them.
phys.org 2023 Switching to hydrogen fuel could prolong the methane problem – by Princeton University
…”… Hydrogen is theoretically the fuel of the future,” said Matteo Bertagni, a postdoctoral researcher at the High Meadows Environmental Institute working on the Carbon Mitigation Initiative. “In practice, though, it poses many environmental and technological concerns that still need to be addressed.”
Bertagni is the first author of a research article published in Nature Communications, in which researchers modeled the effect of hydrogen emissions on atmospheric methane. They found that above a certain threshold, even when replacing fossil fuel usage, a leaky hydrogen economy could cause near-term environmental harm by increasing the amount of methane in the atmosphere. The risk for harm is compounded for hydrogen production methods using methane as an input, highlighting the critical need to manage and minimize emissions from hydrogen production…
…”Managing leakage rates of hydrogen and methane will be critical,” Bertagni said. “If you have just a small amount of methane leakage and a bit of hydrogen leakage, then the blue hydrogen that you produce really might not be much better than using fossil fuels, at least for the next 20 to 30 years.” The researchers emphasized the importance of the time scale over which the effect of hydrogen on atmospheric methane is considered…”….
sciencedirect.com 11-2022 Research progress on CO2 capture and utilization – by Lipei Fu, Zhangkun Ren, Wenzhe Si, Qianli Ma, Weiqiu Huang, Kaili Lia, Zhoulan Huang, Yu Wang, Junhua Li, Peng Xu
- Various traditional and novel CO2 capture and utilization technologies are summarized.
- The challenges and future prospects of CO2 capture and utilization technologies are analyzed.
- The application of CO2 capture technologies in basic industry and pilot plants is reviewed.
- The frontier reports of CO2 resource utilization in different research directions are reviewed.
Abstract – With the expansion of industry, the emission of greenhouse gases is increasing, and its impact on climate is becoming more and more serious. CO2 is the main culprit of the greenhouse effect, and how to effectively solve the climate problem caused by CO2 has attracted more and more attention. In recent years, there have been continuous attempts to reduce CO2 emissions from the source, but no obvious results have been achieved. In fact, CO2 is not only a greenhouse gas, but also a potential carbon resource. Therefore, how to capture and effectively use CO2 is also the research direction that many scholars have been exploring recently. In this paper, the current situations of CO2 capture technologies are reviewed from the aspects of chemical absorption, solid-phase porous materials adsorption, membrane separation, cryogenic separation, hydrate method and microbiological method in the first part. Then, the CO2 utilization technologies are systematically introduced from the aspect of physical utilization, chemical utilization, biological utilization and mineralization utilization. Furthermore, several representative frontier technologies of CO2 resource utilization are reported. On this basis, the advantages and disadvantages of different methods are summarized to provide some ideas and references for alleviating the CO2 issue.

Only a maximum of 40 per cent of the cement content of concrete can be replaced in this way. However, according to Seratech, the carbon capture and storage (CCS) involved to make the replacement material means that more carbon is stored in the concrete than is emitted in its cement production, making it overall carbon-neutral…”…

theverge.com 14-1-2022 Clean energy tech needs to be designed for recycling, experts say – Too many adhesives impede disassembly today – By Maddie Stone
Companies like Apple and Samsung aren’t the only ones making high-tech devices that are hard to take apart and recycle. So are the manufacturers of critical clean energy technologies like solar panels, wind turbines, and electric vehicle (EV) batteries — and unlike the consumer tech industry, which is slowly starting to reverse some of its unsustainable design practices, there isn’t much being done about it. …
“Design for recycling hasn’t really come to that market yet,” says Andy Abbott, a professor of chemistry at the University of Leicester who recently co-authored a review paper on de-bondable adhesives and their potential use in clean energy. Instead, Abbott says, manufacturers tend to “overengineer” their products for safety and durability. Take EV batteries, which are composed of anywhere from dozens to thousands of individual, hermetically-sealed cells glued together inside modules and packs. While the heavy use of adhesives helps ensure the batteries don’t fall apart on the road, it can make them incredibly difficult to take apart in order to repurpose individual cells or recycle critical metals like lithium, cobalt, and nickel. “At the moment, because everything is bonded together, lots of batteries end up getting shredded,” study co-author Gavin Harper, an EV battery recycling expert at the University of Birmingham in the UK, tells The Verge. “The material is mixed together, which makes subsequent steps in the recycling process more complicated.”…
