Charged EVs | Vitality professional: Up to date US Hydrogen Technique is best, however nonetheless designed to prop up the fossil gasoline trade
Michael Barnard writes on all kinds of e-mobility and renewable power matters. In a current article for CleanTechnica, he discusses the most recent version of the US National Clean Hydrogen Strategy and Roadmap, a coverage doc that the DOE produces and updates periodically.
Barnard’s piece is an in depth and extremely technical dialogue of a fancy matter, and must be read in its entirety by those that would enterprise an opinion thereupon. Barnard finds the most recent model (June 2023) of the Hydrogen Technique to be an enchancment over the primary draft, however writes that it nonetheless appears to be aimed extra at supporting the fossil gasoline trade than optimizing the usage of hydrogen know-how to scale back emissions.
Scientists and engineers are likely to agree that there are numerous promising purposes for hydrogen in industrial processes, however that direct electrification is the most effective resolution for transportation (and, regardless of the most effective efforts of the fossil gasoline trade and the politicians on its payroll, the market appears to have already made the choice). As Barnard sees it, the flawed federal division is in command of US hydrogen coverage. The Hydrogen Technique was primarily authored by the DOE, and at the very least for the primary draft, there was “little obvious enter from the precise finish use case sectors for hydrogen as we speak.”
About 25% of the world’s hydrogen is used to fabricate ammonia, largely for fertilizer. Direct discount of iron (DRI) for metal accounts for an additional huge chunk of present hydrogen demand. Cleansing up these industrial processes must be main priorities, so Barnard thinks the Departments of Commerce and Agriculture ought to have extra enter than the DOE, whose principal remit is nuclear power.

“Job one is to decarbonize [hydrogen’s] industrial use instances, not invent new markets it’s badly suited to, however the first draft of the US Hydrogen Technique was largely targeted on inventing new markets,” Barnard writes. Within the new and improved model, the DOE is “making it clear that consultations, nevertheless deep or shallow, did and can contain a number of organizations that are present and future main hydrogen stakeholders.”
The primary alternative areas recognized within the Hydrogen Technique are “the commercial sector (e.g. chemical substances, metal and refining), heavy-duty transportation, and long-duration power storage.”
Barnard agrees with many of the scientific world that the primary merchandise on that listing is the right one. Nonetheless, “Heavy-duty transportation has no pathways for hydrogen in a rational world. Heavy-duty trucking will all electrify, as in-hand battery power densities permit 500-mile ranges as we speak, 1,000-mile ranges in a yr or two, and over double [the ranges of] present long-haul diesel rigs within the 2030s.”
As for rail, exterior of the US, it’s both electrified or quickly electrifying. Rail is 85% electrified in India, 72% in China, and 60% in Europe. It’s laborious to see any opening for hydrogen there, however Barnard tells us that the American Affiliation of Railroads is “belligerently against electrification for nonsensical causes.” For maritime delivery, “it’s going to be batteries and biofuels, not hydrogen derivatives.”
What about long-duration power storage? Hydrogen for this utility is “going to be too costly as a result of inefficiencies and capital prices to compete in day-ahead reserves or two-day markets, so it’s going to be constrained, if ever constructed, to very long-duration storage the place there’s a nationwide scarcity of wind and sunshine for per week,” Barnard writes. “Even then, simply diverting biomethane from present anthropogenic sources into pure fuel storage amenities is much more smart than manufacturing hydrogen for the aim. The reply for economically smart long-duration storage is pumped hydro and the rising redox move battery house, not an costly molecule that likes to leak.”
The DOE says that the Hydrogen Vitality Earthshot launched in 2021 “will catalyze each innovation and scale…and dramatically lowering the price of clear hydrogen.”
Barnard isn’t having any. “This isn’t an area that’s topic to large reductions in worth. The legal guidelines of thermodynamics don’t give strategy to wishful pondering, so the price of inexperienced hydrogen through electrolysis will nonetheless require 50 MWh+ per ton of hydrogen. Solely the electrolyzer just isn’t a commoditized element as we speak, and it’s one in every of maybe 28 parts in an industrial-scale electrolysis plant.”
Following a extremely technical clarification of the elements that drive the price of hydrogen, and why the blue or inexperienced hydrogen (made out of renewable power) that H2 followers like to tout will all the time price greater than black or grey hydrogen (made out of fossil fuels), Barnard concludes: “Hydrogen is as low cost because it’s ever going to get, even with the IRA’s large subsidy per kg (equal to $3.00 per gallon of gasoline, or 83% of the retail worth proper now). We don’t use it for power…as a result of it’s vastly dearer than fossil fuels, and we gained’t use it for power sooner or later until we’re financial idiots, as a result of electrification and biofuels are cheaper.”
The Hydrogen Technique requires grants and loans for automakers to fabricate gasoline cell EVs, in addition to tax credit for amenities that manufacture hydrogen and gasoline cell applied sciences. “Yup, let’s give cash to home producers to make gasoline cells and gasoline cell vehicles nobody will purchase or drive,” says Barnard. “That’s pure pork.
Barnard cites David Cebon of the Centre for Sustainable Road Freight, who present in 2022 that hydrogen vans from main distributors have been way more costly than their battery-powered alternate options, and that gasoline prices can be 3 times dearer than utilizing electrical energy. Barnard additionally reminds us that China has 1.1 million electrical buses and vans on its roads, and fewer than 10,000 gasoline cell autos. “If the USA desires to compete within the twenty first century with China, it has to take action with pragmatic selections that make sense, not financial useless ends that fulfill solely the fossil gasoline trade.”
By now you’ve gathered that Mr. Barnard just isn’t impressed with the US Hydrogen Technique, which he calls “a doc the fossil gasoline trade will love,” that recommends “numerous governmental cash to be used instances for hydrogen and carbon seize that may fail, perpetuating their enterprise mannequin for an additional decade or two on the expense of the planet.”
Nonetheless, all just isn’t misplaced. The most recent version of the Hydrogen Technique is an enchancment over the primary draft. “Extra stakeholders are clearly known as out, and there’s a transparent all-of-government strategy that was missing within the authentic. There’s extra focus and readability on the precise use instances for lower-carbon hydrogen—ammonia and metal outstanding amongst them. And all the residential and business heating potential for hydrogen has disappeared. They lastly acquired that memo.”
For optimists who observe the hydrogen-vs-battery debate, there are indicators that the wave of hydrogen fever has crested. “If the DOE updates [the Hydrogen Strategy] each 9 months, and there’s as a lot motion every time, then by 2026 or 2027, it may very well be a superb technique,” Barnard concludes.
