The Real Reason Hydrogen Fuel Isn't More Popular
There's no chemical element more abundant than hydrogen in the universe, but it's still difficult to obtain in a pure and ready-to-use form. To use it in the same way we use oil and gas, we must manufacture it. The problem is that the manufacturing process itself usually releases significant climate-warming emissions. There is little point in using clean hydrogen energy if the process to create it negates its benefits.

The Problems With Manufacturing Hydrogen
Data from the International Energy Agency (IEA), shows that 96% of hydrogen fuel production around the world uses fossil fuels -- releasing at least nine tons of carbon dioxide (CO₂) per ton of hydrogen, and even up to twelve tons. The various production processes used impact the levels of CO₂ emitted.
Most of the hydrogen used today -- including around 95% of projects in the U.S. -- is known as gray hydrogen; made by breaking down natural gas using high heat. While this process does produce hydrogen, it also releases about 12 kilograms of CO₂ for every single kilogram of hydrogen. A cleaner option is blue hydrogen, which uses the same method but adds carbon capture technology to trap some of the emissions. Even then, it still releases three to five kilograms of CO₂ per kilogram of hydrogen.
As part of a team researching new ways of creating hydrogen, without direct CO₂ emissions, Professor Graham Hutchings of Cardiff University stated, "Finding sustainable ways of creating the products we need for everyday life and to meet net zero ambitions for the future is a key challenge facing the chemical industry. Hydrogen is widely regarded as one way of achieving these ambitions because it is made from natural gas. However, it is extremely energy intensive and, of course, when created through traditional methods, it produces large amounts of carbon dioxide limiting its environmental benefits."
Research Into Cleaner Ways To Produce Hydrogen
One potential process which would be safer for our climate, is an option referred to as green hydrogen. This utilizes clean and renewable energy, like wind or solar power, to manufacture the hydrogen. The process can emit one kilogram or less of harmful emissions, which is significantly less than the current processes in place for gray and blue hydrogen.
Researching the concept at the Massachusetts Institute of Technology (MIT) Energy Initiative, a key stumbling block is the cost of the electrolyzers that are used to split the hydrogen from water. Furthermore, wind and solar power aren't reliable enough for a continuous manufacturing process. That leaves the options of either stopping production when conditions are not ideal, or having to rely on more traditional methods of producing hydrogen, which is counterintuitive.
Principal research scientist at the MIT Energy Initiative, Emre Gençer, explained, "If we get cheaper electrolyzers, you will definitely see more green hydrogen coming online ... The reason we are talking about hydrogen today [is] because there are hard to abate sectors with electrification or other decarbonization options, and that's why we see hydrogen as a solution. But that completely depends on how clean our hydrogen production is."

Scientists Say New Government Climate Report Twists Their Work
Jul 30, 2025 4:31 PM A new Department of Energy report 'fundamentally misrepresents' climate research and leaves out key context, multiple scientists cited in the report tell WIRED.

However, we may receive compensation from retailers and/or from purchases of products through these links. A new report released yesterday by the Department of Energy purports to provide 'a critical assessment of the conventional narrative on climate change.' But nine scientists across several different disciplines told WIRED that the report mishandled citations of their work: by cherrypicking data, misrepresenting findings, drawing erroneous conclusions, or leaving out relevant context. This report was introduced on the same day that the EPA announced it would seek to roll back the endangerment finding, a crucial 2009 ruling that provides the scientific and legal basis for the agency to regulate greenhouse gasses under the Clean Air Act. In its draft reconsideration of the finding, the EPA cites the paper from the DOE as part of a review of 'the most recently available science' that it undertook to challenge the validity of the 2009 ruling. 'The goal is to restore confidence in science, in data, in rationalism. That's what enabled the creation of modern science,' DOE Secretary Chris Wright said in an Fox interview Tuesday with EPA Administrator Lee Zeldin, to celebrate what Zeldin called 'the largest deregulatory action in the history of the United States.' 'We slid back into sort of a cancel culture, Orwellian squelching of science in talking about 'the' science, as opposed to the process that is science,' Wright continued. 'We need to restore some common sense around climate change and energy.' The report was authored by four scientists and one economist who are familiar contrarians in the climate science world. Three of the report's authors were recently hired at the Energy Department, the New York Times reported earlier this month, prompting alarm among mainstream scientists who have long followed their work. Each author has a long history of producing work that challenges mainstream consensus on climate science. Their work is often promoted by interests seeking to discredit scientific findings or downplay climate action. The DOE report's summary states that it finds '[CO 2 ]-induced warming appears to be less damaging economically than commonly believed, and that aggressive mitigation strategies could be more harmful than beneficial.' Many of the arguments reflected in the new DOE paper, mainstream scientists told WIRED, have been debunked over and over for years. 'I'm a bit surprised that the government put out something like this as an official publication,' Zeke Hausfather, the climate research lead at tech company Stripe and a research scientist at the climate nonprofit Berkeley Earth, told WIRED in an email. 'It reads like a blog post—a somewhat scattershot collection of oft-debunked skeptic claims, studies taken out of context, or cherry-picked examples that are not representative of broader climate science research findings.' The DOE says that it is opening the report up to a public comment process. In an email, Department of Energy spokesperson Andrea Woods said that the questions WIRED sent over about the use of research in specific portions of the report were too complex for the agency to answer thoroughly on a short turnaround, and encouraged scientists who spoke with WIRED to submit a public comment to the federal register. 'The Climate Working Group and the Energy Department look forward to engaging with substantive comments following the conclusion of the 30-day comment period,' Woods wrote. 'This report critically assesses many areas of ongoing scientific inquiry that are frequently assigned high levels of confidence—not by the scientists themselves but by the political bodies involved, such as the United Nations or previous Presidential administrations. Unlike previous administrations, the Trump administration is committed to engaging in a more thoughtful and science-based conversation about climate change and energy.' Ben Santer, a climate researcher and an honorary professor at the University of East Anglia, has a long history with some of the authors of the new report. (Santer's research is also cited in the DOE report; he, like other scientists who spoke to WIRED, say the report 'fundamentally misrepresents' his work.) In 2014, Santer was part of an exercise at the American Physical Society (APS), one of the largest scientific membership organizations in the country. Known as a red team vs blue team exercise, it pitted proponents of mainstream climate science against contrarians—including two authors of the current DOE report—to work through whether their claims had merit. The exercise was convened by Steve Koonin, one of the new hires at the Department of Energy and an author of the report. As Inside Climate News reported in 2021, Koonin resigned from his leadership role after APS refused to adopt a modified statement on climate science that he proposed following the exercise. Koonin later unsuccessfully pitched a similar exercise to the first Trump White House. 'These guys have a history of being wrong on important scientific issues,' Santer says. 'The notion that their views have been given short shrift by the scientific community is just plain wrong.' Hausfather's work is cited twice in the report in a section challenging emissions scenarios: projections of how much CO 2 will be emitted into the atmosphere under various different pathways. These citations, Hausfather says, are 'instructive' to see how the DOE report's authors 'cherrypick data points that suit their narrative.' The report includes a chart from a 2019 paper of his that, the DOE authors say, shows how climate models have 'consistently overestimated observations' of atmospheric CO 2 . However, Hausfather tells WIRED, the key finding of his 2019 research was that historic climate models were actually remarkably accurate in predicting warming. 'They appear to have discarded the whole paper as not fitting their narrative, and instead picked a single figure that was in the supplementary materials to cast doubt on models, when the whole paper actually confirmed how well they have performed in the years after they were published,' he tells WIRED. (Hausfather's research was also cited in the EPA's justification for rolling back the endangerment finding—which, he said in a post on X, draws a 'completely backwards' conclusion from his work.) It's not just Hausfather who feels his work was mishandled. Much of the early section of the report discusses how beneficial carbon dioxide is to plant growth, a claim that has been repeated by Secretary Wright as a 'plus' to global warming. The authors cite 2010 research from evolutionary biologist Joy Ward, now the provost and executive vice president of Case Western Reserve University, to support claims that plant life will flourish with more CO 2 in the atmosphere. Ward, however, told WIRED in an emailed statement that her experiments were conducted under 'highly controlled growth conditions' to create a 'mechanistic understanding' of CO 2 , and that climate change can cause a host of impacts on plants not accounted for in her study. 'With rising CO 2 in natural ecosystems, plants may experience higher heat loads, extreme weather events such as droughts and floods, and reduced pollinators—which can have severe net negative effects on plant growth and crop yields,' she says. 'Furthermore, our studies indicate that major disruptions in plant development such as flowering time can occur in direct response to rising CO 2 , which were not mentioned in the report.' The DOE report's section on ocean acidification cites research by Josh Krissansen-Totton, an assistant professor at the University of Washington who specializes in planetary science and biogeochemistry, to support a claim that 'the recent decline in [ocean] pH is within the range of natural variability on millennial time scales.' Research has shown that the oceans have been absorbing CO 2 from the atmosphere since the beginning of the industrial revolution, causing it to become considerably more acidic over the past two centuries. 'Ocean life is complex and much of it evolved when the oceans were acidic relative to the present,' that section of the report states. 'The ancestors of modern coral first appeared about 245 million years ago. CO 2 levels for more than 200 million years afterward were many times higher than they are today.' Krissansen-Totton told WIRED in an email that his work on ocean acidity billions of years ago has 'no relevance' to the impacts of human-driven ocean acidification today, and that today calcium carbonate saturation is quickly diminishing in the ocean alongside rising acidity. Dissolved calcium carbonate is essential for many marine species, particularly those that rely on it to build their shells. 'The much more gradual changes in ocean pH we observe on geologic timescales were typically not accompanied by the rapid changes in carbonate saturation that human CO 2 emissions are causing, and so the former are not useful analogs for assessing the impact of ocean acidification on the modern marine biosphere,' he says. The consensus among mainstream academics around climate change's severity and importance does not mean that there aren't still open questions about portions of the science. Jeff Clements, a marine ecologist who runs a research lab at Canada's federal fisheries and ocean department, says that the way the DOE report cites his research on ocean acidification and fish behavior is accurate 'from an explicit textual perspective.' Clements's work on this topic focuses on correcting alarming earlier studies connecting the effects of ocean acidification on fish. In the DOE report, his work is used to bolster the section downplaying ocean acidification. 'Much of the public discussion of the effects of ocean 'acidification' on marine biota has been one-sided and exaggerated,' the DOE report states. Clements said in an email to WIRED that just because his review of the literature found fish behavior to be relatively unaffected by ocean acidification does not mean that a myriad of other ocean ecosystems, biological processes, and species will fare similarly. Other work from his lab, meanwhile, has underscored the vulnerability of mussels to ocean warming and looked at how heatwaves negatively alter clam behavior. 'I want to make it clear that our results should not be interpreted to mean 'ocean acidification (or climate change more generally) is not a problem,'' he tells WIRED. 'While effects on fish behavior may not be as severe as initially thought, other species and biological processes are certainly vulnerable to the impacts of acidification and the compendium of other climate change stressors that our oceans are experiencing.' Richard Seager, a research professor at the Lamont-Doherty Earth Observatory of Columbia University, coauthored a paper cited in the DOE report on the discrepancy between what climate models predict and what is actually being measured when it comes to sea-surface temperatures in the Pacific Ocean. 'I think acceptance has been growing that the models have been getting something wrong in the tropical Pacific,' he says. 'That and what this means for the future however is very much an area of intense research.' (A separate study on agricultural yields coauthored by Seager, he says, is misrepresented in another section of the report.) The future of further research on this topic and other open questions in climate science is in limbo six months into the second Trump administration. The irony of the report's promotion at a time when the White House is launching multiple fronts of attacks on traditional science—including removing the authors of the National Climate Assessment from their roles in April—is not lost on mainstream scientists. 'This report had five authors and was rushed over four months, and would not pass muster in any traditional scientific peer-review process,' says Hausfather. 'The fact that this has been released at the same time that the government has hidden the actual congressionally mandated national climate assessments that accurately reflect the science only further shows how much of a farce this is.'
