“Having lower energy prices is good for everybody,” Bryan Fisher, a managing director at the energy think tank RMI focused on industrial decarbonization, told me simply. And so when those prices go up, “the biggest macro theme is it hurts industries or applications of industry unevenly — green hydrogen being the biggest one.”
There was a general consensus among the people I spoke with that electrolytic hydrogen — known as green hydrogen if it’s produced with renewable electricity — is the clearest casualty here. That’s unsurprising given that electricity drives roughly 60% to 70% of its production cost, as it powers the process that splits water into hydrogen and oxygen. Rising hydrogen costs will also have knock-on effects across other emergent industries, as many companies and investors are banking on green hydrogen to replace fossil fuels in hard-to-electrify sectors such as chemical production or long-haul transport.
Fisher told me that rising electricity costs now means that the transition from blue hydrogen — produced from natural gas feedstock, with carbon capture and storage to control emissions — to green hydrogen will be prolonged. “What we always thought was going to happen was that a blue hydrogen market would develop and be replaced by green as those costs went down,” Fisher explained. “So I think the time at which the market will utilize low-emissions blue hydrogen is just extended.”
Dan Lashof, the former U.S. director and a current senior fellow at the World Resources Institute, told me that if and when hydrogen projects scale, circumventing the rising costs of grid electricity with behind-the-meter renewable power could be a viable option, given that new wind and solar generation remains quite cheap. He also emphasized the other factors at play when it comes to making green hydrogen economically feasible — mainly the high cost of electrolyzers themselves, the devices that split water into its component parts. “Tariffs on Chinese imports are going to be a big factor in terms of electrolyzer costs,” he told me. That leads him to ask, “will other countries like India step up and be able to produce low cost electrolyzers for the U.S. market?”
Among industries that rely on green hydrogen, sustainable aviation and green shipping might suffer the most, as hydrogen is a necessary ingredient in certain net-zero fuels. But high electricity prices — and by extension green hydrogen costs — are far from their only financial concern. Producing clean fuels often requires combining hydrogen with captured carbon to synthesize hydrocarbons.Sourcing and capturing CO2, breaking it down into carbon monoxide, and synthesizing hydrocarbons are all expensive in and of themselves.
Fisher told me that when it comes to the category of sustainable aviation fuels known as e-SAF, which is made from green hydrogen and captured carbon dioxide, innovations in these other areas — as well as economies of scale — are more likely to make a meaningful dent in fuel prices than cheaper electricity. “Power prices going up 20% adds about $1 or $1.50 a gallon to e-SAF,” he explained. “And right now we’re probably $5 to $7 out of the money.” So while lower electricity prices would certainly be welcome, the industry needs cost breakthroughs on multiple fronts before this fuel has a shot at competing.
Some companies, including Twelve, require electrolyzers to break down both CO2 and H2O. Rajesh Swaminathan, a partner at Khosla Ventures, told me he simply doesn’t think the current approaches to e-SAF will get there economically. “It’s a terrible economic idea. It doesn’t pass any kind of sniff test,” he said. “Even if electricity prices were extremely low, this will not be competitive from a capex and opex perspective,” he said, referring to both capital expenditures and the cost of operating the business.
Khosla has instead invested in Lanzatech, which sources carbon-rich gases from industrial facilities such as steel mills and ferments them into ethanol, which can then be chemically converted into jet fuel. Its core process doesn’t rely on green hydrogen or electrolysis at all. “That’s such a low-cost approach that will meet the SAF targets of $4 per gallon,” Swaminathan told me — a claim that remains to be seen, of course.
Efforts to decarbonize high heat industrial processes such as steel and cement production also rely heavily on electrification. The clean cement company Sublime Systems and clean steel companies Boston Metal and Electra, for instance, all use electricity-driven chemical processes to replace the need for burning fossil fuels in either cement kilns or the blast furnaces used in steel production.
The companies themselves often emphasize the importance of low electricity prices for making this tech cost-competitive. For example, when Boston Metal’s CEO Tadeu Carneiro was asked by a Time magazine reporter two years ago about where the company would source the enormous amount of electricity needed to melt iron ore as planned, he replied, “If you don’t believe that electricity will be plentiful, reliable, available, green, and cheap, forget about it,” essentially acknowledging the tech won’t pencil out in the absence of cheap power. He added that there are regions such as Quebec and Scandinavia — both of which have abundant hydropower resources — where it would make economic sense to deploy Boston Metal’s tech sooner rather than later. Similarly, Sublime is building its first commercial-scale clean cement plant in Holyoke, Massachusetts, where it’s sourcing power from the city’s hydroelectric dam.
“We have to believe that the electricity will be available,” Carneiro told Time.
Lashof told me that in the meantime, higher electricity prices will “push industrial decarbonization more towards using carbon capture and sequestration pathways” over electrification-driven approaches. But Fisher thinks that in many cases there’s still “headroom” for electrification of power and heat to make sense domestically, even with a relatively significant “20% to 30% type increase” in electricity costs.
“If you’re doing a heat by electrification project at your industrial site, in some cases it’s an adaptive problem, not an economic problem.” he told me. Indeed, plants will need to be redesigned — no small cost in itself — and teams must be willing to change their systems and processes to accommodate new technologies. That organizational inertia could, in some cases, prevent the adoption of novel electrification tech, even if electricity prices would support it.
One technology that Fisher is absolutely certain isn’t constrained by electricity prices so much as the lack of a fundamental technical breakthrough is engineered carbon removal, such as direct air capture. “Innovation is the key, not low power prices, because we need to get from $500 bucks a ton in carbon removal to $50 bucks a ton,” he told me. While DAC certainly requires loads of electricity to pull CO2 out of the air and chemically separate it, that won’t be enough to conjure the 90% price reduction necessary before DAC can reach scale.
But rest assured, rising electricity prices will also create some winners, with energy efficiency likely to be at the top of the list, Duncan Turner, a general partner at venture capital firm SOSV, told me. Personally, he’s excited about everything from innovations in HVAC systems to companies developing more energy-efficient chemical separation processes, low-power light-based data transfer hardware for data centers, and plasma-based cooling products for computing chips.
Energy efficiency isn’t the only category he thinks stands to benefit. “There’s a bunch of long-duration energy storage companies that will look very interesting indeed as the price of electricity starts to go up and the demand for electricity from data centers starts to peak,” Turner told me. Like Fisher, he also sees an opportunity for point-source carbon capture, viewing it as a way to “very quickly get cheaper and cleaner electricity onto the grid.”
Moments like these are also when investors are quick to remind us that betting on consistency across seemingly any dimension — whether that’s clean energy incentives, the funding environment, or commodity prices — is often a losing strategy. Or, as Turner put it, “It’s probably for the good for the whole industry — our community as a whole — that we reset to, We work better than anything else, even when there’s expensive electricity.”
