The Biden administration is hoping they’ll be a starting gun for the industry. The industry may or may not be fully satisfied.
In one of the Biden administration’s final acts to advance decarbonization, and after more than two years of deliberation and heated debate, the Treasury Department issued the final requirements governing eligibility for the clean hydrogen tax credit on Friday.
At up to $3 per kilogram of clean hydrogen produced, this was the most generous subsidy in the 2022 Inflation Reduction Act, and it came with significant risks if the Treasury did not get the rules right. Hydrogen could be an important tool to help decarbonize the economy. But without adequate guardrails, the tax credit could turn it into a shovel that digs the U.S. deeper into a warming hole by paying out billions of dollars to projects that increase emissions rather than reducing them.
In the final guidelines, the Biden administration recognized the severity of this risk. It maintained key safeguards from the rules proposed in 2023, while also making a number of changes, exceptions, and other “flexibilities” — in the preferred parlance of the Treasury Department — that sacrifice rigorous emissions accounting in favor of making the program easier to administer and take advantage of.
For example, it kept a set of requirements for hydrogen made from water and electricity known as the “three pillars.” Broadly, they compel producers to match every hour of their operation with simultaneous clean energy generation, buy this energy from newly built sources, and ensure those sources are in the same general region as the hydrogen plant. Hydrogen production is extremely energy-intensive, and the pillars were designed to ensure that it doesn’t end up causing coal and natural gas plants to run more. But the final rules are less strict than the proposal. For example, the hourly matching requirement doesn’t apply until 2030, and existing nuclear plants count as new zero-emissions energy if they are considered to be at risk of retirement.
Finding a balance between limiting emissions and ensuring that the tax credit unlocks development of this entirely new industry was a monumental challenge. The Treasury Department received more than 30,000 comments on the proposed rule, compared to about 2,000 for the clean electricity tax credit, and just 89 for the electric vehicle tax credit. Senior administration officials told me this may have been the most complicated of all of the provisions in the IRA. In October, the department assured me that the rules would be finished by the end of the year.
Energy experts, environmental groups, and industry are still digesting the rule, and I’ll be looking out for future analyses of the department’s attempt at compromise. But initial reactions have been cautiously optimistic.
On the environmental side, Dan Esposito from the research nonprofit Energy Innovation told me his first impression was that the final rule was “a clear win for the climate” and illustrated “overwhelming, irrefutable evidence” in favor of the three pillars approach, though he did have concerns about a few specific elements that I’ll get to in a moment. Likewise, Conrad Schneider, the U.S. senior director at the Clean Air Task Force, told me that with the exception of a few caveats, “we want to give this final rule a thumbs up.”
Princeton University researcher Jesse Jenkins, a co-host of Heatmap’s Shift Key podcast and a vocal advocate for the three pillars approach, told me by email that, “Overall, Treasury’s final rules represent a reasonable compromise between competing priorities and will provide much-needed certainty and a solid foundation for the growth of a domestic clean hydrogen industry.”
On the industry side, the Fuel Cell and Hydrogen Energy Association put out a somewhat cryptic statement. CEO Frank Wolak applauded the administration for making “significant improvements” but warned that the rules were “still extremely complex” and contain several open-ended parts that will be subject to interpretation by the incoming Trump-Vance administration.
“This issuance of Final Rules closes a long chapter, and now the industry can look forward to conversations with the new Congress and new Administration regarding how federal tax and energy policy can most effectively advance the development of hydrogen in the U.S.,” Wolak said.
Constellation Energy, the country’s biggest supplier of nuclear power, was among the most vocal critics of the proposed rule and had threatened to sue the government if it did not create a pathway for hydrogen plants that are powered by existing nuclear plants to claim the credit. In response to the final rule, CEO and President Joe Dominguez said he was “pleased” that the Treasury changed course on this and that the final rule was “an important step in the right direction.”
The California governor’s office, which had criticized the proposed rule, was also swayed. “The final rules create the certainty needed for developers to invest in and build clean, renewable hydrogen production projects in states like California,” Dee Dee Myers, the director of the Governor’s Office of Business and Economic Development, said in a statement. The state has plans to build a $12.6 billion hub for producing and using clean hydrogen.
Part of the reason the Treasury needed to find a Goldilocks compromise that pleased as many stakeholders as possible was to protect the rule from future lawsuits and lobbying. But not everyone got what they wanted. For example, the energy developer NextEra, pushed the administration to get rid of the hourly matching provision, which though delayed remained essentially untouched. NextEra did not respond to a request for comment.
Companies that fall on the wrong side of the final rules may still decide to challenge them in court. The next Congress could also make revisions to the underlying tax code, or the incoming Trump administration could change the rules to perhaps make them more favorable to hydrogen made from fossil fuels. But all of this would take time — a rule change, for example, would trigger a whole new notice and comment process. Though the one thing I’ve heard over and over is that the industry wants certainty, which the final rule provides, it’s not yet clear whether that will outweigh any remaining gripes.
In the meantime, it's off to the races for the nascent clean hydrogen industry. Between having clarity on the tax credit, the Department of Energy’s $7 billion hydrogen hubs grant program, and additional federal grants to drive down the cost of clean hydrogen, companies now have numerous incentives to start building the hydrogen economy that has received much hype but has yet to prove its viability. The biggest question now is whether producers will find any buyers for their clean hydrogen.
Below is a more extensive accounting of where the Treasury landed in the final rules.

On “deliverability,” or the requirement to procure clean energy from the same region, the rules are largely unchanged, although they do allow for some flexibility on regional boundaries.
As I explained above, the Treasury Department also kept the hourly matching requirement, but delayed it by two years until 2030 to give the market more time to set up systems to achieve it — a change Schneider said was “really disappointing” due to the potential emissions consequences. Until then, companies only have to match their operations with clean energy on an annual basis, which is a common practice today. The new deadline is strict, and those that start operations before 2030 will not be grandfathered in — that is, they’ll have to switch to hourly matching once that extended clock runs out. In spite of that, the final rules also ensure that producers won’t be penalized if they are not able to procure clean energy for every single hour their plant operates, an update several groups applauded.
On the requirement to procure clean power from newly built sources, also known as “incrementality,” the department made much bigger changes. It kept an overarching definition that “incremental” generators are those built within three years of the hydrogen plant coming into service, but added three major exceptions:
1. If the hydrogen facility buys power from an existing nuclear plant that’s at risk of retirement.
2. If the hydrogen facility is in a state that has both a robust clean electricity standard and a broad, binding, greenhouse gas cap, such as a cap and trade system. Currently, only California and Washington pass this test.
3. If the hydrogen facility buys power from an existing natural gas or coal plant that has added new carbon capture and storage capacity within three years of the hydrogen project coming into service.
The hydrogen tax credit is so lucrative that environmental groups and energy analysts were concerned it would drive companies like Constellation to start selling all their nuclear power to hydrogen plants instead of to regular energy consumers, which could drive up prices and induce more fossil fuel emissions.
The final rules try to limit this possibility by only allowing existing reactors that are at risk of retirement to qualify. But the definition of “at risk of retirement” is loose. It includes “merchant” nuclear power plants — those that sell at least half their power on the wholesale electricity market rather than to regulated utilities — as well as plants that have just a single reactor, which the rules note have lower or more uncertain revenue and higher operational costs. Looking at the Nuclear Energy Institute’s list of plants, merchant plants make up roughly 40% of the total. All of Constellation Energy’s plants are merchant plants.
There are additional tests — the plant has to have had average annual gross receipts of less than 4.375 cents per kilowatt hour for at least two calendar years between 2017 and 2021. It also has to obtain a minimum 10-year power purchase agreement with the hydrogen company. Beyond that, the reactors that meet this definition are limited to selling no more than 200 megawatts to hydrogen companies, which is roughly 20% for the average reactor.
Esposito, who has closely analyzed the potential emissions consequences of using existing nuclear plants to power hydrogen production, was not convinced by the safeguards. “I don't love the power price look back,” he told me, “because that's not especially indicative of the future — particularly this high load growth future that we're quickly approaching with data centers and everything. It’s very possible power prices could go up from that, and then all of a sudden, the nuclear plants would have been fine without hydrogen.”
As for the 200 megawatt cap, Esposito said it was better than nothing, but he feels “it's kind of an implicit admission that it's not really, truly clean” to produce hydrogen with the energy from these nuclear plants.
Schneider, on the other hand, said the safeguards for nuclear-powered hydrogen projects were adequate. While a lot of plants are theoretically eligible, not all of their electricity will be eligible, he said.
The rules assert that in states that meet the two criteria of a clean electricity standard and a binding cap on emissions, “any increased electricity load is highly unlikely to cause induced grid emissions.”
But in a paper published in February, Energy Innovation explored the potential consequences of this exemption in California. It found that hydrogen projects could have ripple effects on the cap and trade market, pushing up the state’s carbon price and triggering the release of extra carbon emission allowances. “In other words, the California program is more of a ‘soft’ cap than a binding one — the emissions budget ‘expands or contracts in response to price bounds set by the legislature and [California Air Resources Board],’” the report says.
Esposito thinks the exemption is a risk, but that it requires further analysis and he’s not sounding the alarm just yet. He said it could come down to other factors, including how economical hydrogen production in California ends up being.
Producers are also eligible for the tax credit if they make hydrogen the conventional way, by “reforming” natural gas, but capture the emissions released in the process. For this pathway, the Treasury had to clarify several accounting questions.
First, there’s the question of how producers should account for methane leaked into the atmosphere upstream of the hydrogen plant, such as from wells and pipelines. The proposal had suggested using a national average of 0.9%. But researchers found this would wildly underestimate the true warming impact of hydrogen produced from natural gas. It could also underestimate emissions from natural gas producers that have taken steps to reduce methane leakage. “We branded that as one size fits none,” Schneider told me.
The final rules create a path for producers to use more accurate, project-specific methane emissions rates in the future once the Department of Energy updates a lifecycle emissions tool that companies have to use called the “GREET” model. The Environmental Protection Agency recently passed new methane emissions laws that will enable it to collect better data on leakage, which will help the DOE update the model.
Schneider said that’s a step in the right direction, though it will depend on how quickly the GREET model is updated. His bigger concern is if the Trump administration weakens or eliminates the EPA’s methane emissions regulations.
The Treasury also opened up the potential for companies to produce hydrogen from alternative, cleaner sources of methane, like gas captured from wastewater, animal manure, and coal mines. (The original rule included a pathway for using gas captured from landfills.) In reality, hydrogen plants taking this approach are unlikely to use gas directly from these sources, but rather procure certificates that say they have “booked” this cleaner gas and can “claim” the environmental benefits.
Leading up to the final rule, some climate advocates were concerned that this system would give a boost to methane-based hydrogen production over electricity-based production, as it's cheaper to buy renewable natural gas certificates than it is to split water molecules. Existing markets for these credits also often overestimate their benefits — for example, California’s low carbon fuel system gives biogas captured from dairy farms a negative carbon intensity score, even though these projects don’t literally remove carbon from the atmosphere.
The Treasury tried to improve its emissions estimates for each of these alternative methane sources to make them more accurate, but negative carbon intensity scores are still possible.
The department did make one significant change here, however. It specified that companies can’t just buy a little bit of cleaner methane and then average it with regular fossil-based methane — each must be considered separately for determining tax credit eligibility. Jenkins, of Princeton, told me that without this rule, huge amounts of hydrogen made from regular natural gas could qualify.
Producers also won’t be able to take this “book and claim” approach until markets adapt to the Treasury’s reporting requirements, which isn’t expected until at least 2027.

The multi-faceted investment is defense-oriented, but could also support domestic clean energy.
MP Materials is the national champion of American rare earths, and now the federal government is taking a stake.
The complex deal, announced Thursday, involves the federal government acting as a guaranteed purchaser of MP Materials’ output, a lender, and also an investor in the company. In addition, the Department of Defense agreed to a price floor for neodymium-praseodymium products of $110 per kilogram, about $50 above its current spot price.
MP Materials owns a rare earths mine and processing facility near the California-Nevada border on the edges of the Mojave National Preserve. It claims to be “the largest producer of rare earth materials in the Western Hemisphere,” with “the only rare earth mining and processing site of scale in North America.”
As part of the deal, the company will build a “10X Facility” to produce magnets, which the DOD has guaranteed will be able to sell 100% of its output to some combination of the Pentagon and commercial customers. The DOD is also kicking in $150 million worth of financing for MP Materials’ existing processing efforts in California, alongside $1 billion from Wall Street — specifically JPMorgan Chase and Goldman Sachs — for the new magnet facility. The company described the deal in total as “a multi-billion-dollar commitment to accelerate American rare earth supply chain independence.”
Finally, the DOD will buy $400 million worth of newly issued stock in MP Materials, giving it a stake in the future production that it’s also underwriting.
Between the equity investment, the lending, and the guaranteed purchasing, the Pentagon, and by extension the federal government, has taken on considerable financial risk in casting its lot with a company whose primary asset’s previous owner went bankrupt a decade ago. But at least so far, Wall Street is happy with the deal: MP Materials’ market capitalization soared to over $7 billion on Thursday after its share price jumped over 40%, from a market capitalization of around $5 billion on Wednesday and the company is valued at around $7.5 billion as of Friday afternoon.
Despite the risk, former Biden administration officials told me they would have loved to make a deal like this.
When I asked Alex Jacquez, who worked on industrial policy for the National Economic Council in the Biden White House, whether he wished he could’ve overseen something like the DOD deal with MP Materials, he replied, “100%.” I put the same question to Ashley Zumwalt-Forbes, a former Department of Energy official who is now an investor; she said, “Absolutely.”
Rare earths and critical minerals were of intense interest to the Biden administration because of their use in renewable energy and energy storage. Magnets made with neodymium-praseodymium oxide are used in the electric motors found in EVs and wind turbines, as well as for various applications in the defense industry.
MP Materials will likely have to continue to rely on both sets of customers. Building up a real domestic market for the China-dominated industry will likely require both sets of buyers. According to a Commerce Department report issued in 2022, “despite their importance to national security, defense demand for … magnets is only a small portion of overall demand and insufficient to support an economically viable domestic industry.”
The Biden administration previously awarded MP Materials $58.5 million in 2024 through the Inflation Reduction Act’s 48C Advanced Energy Project tax credit to support the construction of a magnet facility in Fort Worth. While the deal did not come with the price guarantees and advanced commitment to purchase the facility’s output of the new agreement, GM agreed to come on as an initial buyer.
Matt Sloustcher, an MP Materials spokesperson, confirmed to me that the Texas magnet facility is on track to be fully up and running by the end of this year, and that other electric vehicle manufacturers could be customers of the new facility announced on Thursday.
At the time MP Materials received that tax credit award, the federal government was putting immense resources behind electric vehicles, which bolstered the overall supply supply chain and specifically demand for components like magnets. That support is now being slashed, however, thanks to the One Big Beautiful Bill Act, which will cancel consumer-side subsidies for electric vehicle purchases.
While the Biden tax credit deal and the DOD investment have different emphases, they both follow on years of bipartisan support for MP Materials. In 2020, the DOD used its authority under the Defense Production Act to award almost $10 million to MP Materials to support its investments in mineral refining. At the time, the company had been ailing in part due to retaliatory tariffs from China, cutting off the main market for its rare earths. The company was shipping its mined product to China to be refined, processed, and then used as a component in manufacturing.
“Currently, the Company sells the vast majority of its rare earth concentrate to Shenghe Resources,” MP Materials the company said in its 2024 annual report, referring to a Chinese rare earths company.
The Biden administration continued and deepened the federal government’s relationship with MP Materials, this time complementing the defense investments with climate-related projects. In 2022, the DOD awarded a contract worth $35 million to MP Materials for its processing project in order to “enable integration of [heavy rare earth elements] products into DoD and civilian applications, ensuring downstream [heavy rare earth elements] industries have access to a reliable feedstock supplier.”
While the DOD deal does not mean MP Materials is abandoning its energy customers or focus, the company does appear to be to the new political environment. In its February earnings release, the company mentioned “automaker” or “automotive-grade magnets” four times; in its May earnings release, that fell to zero times.
Former Biden administration officials who worked on critical minerals and energy policy are still impressed.
The deal is “a big win for the U.S. rare earths supply chain and an extremely sophisticated public-private structure giving not just capital, but strategic certainty. All the right levers are here: equity, debt, price floor, and offtake. A full-stack solution to scale a startup facility against a monopoly,” Zumwalt-Forbes, the former Department of Energy official, wrote on LinkedIn.
While the U.S. has plentiful access to rare earths in the ground, Zumwalt-Forbes told me, it has “a very underdeveloped ability to take that concentrate away from mine sites and make useful materials out of them. What this deal does is it effectively bridges that gap.”
The issue with developing that “midstream” industry, Jacquez told me, is that China’s world-leading mining, processing, and refining capacity allows it to essentially crash the price of rare earths to see off foreign competitors and make future investment in non-Chinese mining or processing unprofitable. While rare earths are valuable strategically, China’s whip hand over the market makes them less financially valuable and deters investment.
“When they see a threat — and MP is a good example — they start ramping up production,” he said. Jacquez pointed to neodymium prices spiking in early 2022, right around when the Pentagon threw itself behind MP Materials’ processing efforts. At almost exactly the same time, several state-owned Chinese rare earth companies merged. Neodymium-praseodymium oxide prices fell throughout 2022 thanks to higher Chinese production quotas — and continued to fall for several years.
While the U.S. has plentiful access to rare earths in the ground, Zumwalt-Forbes told me, it has “a very underdeveloped ability to take that concentrate out away from mine sites and make useful materials out of them. What this deal does is it effectively bridges that gap.”
The combination of whipsawing prices and monopolistic Chinese capacity to process and refine rare earths makes the U.S.’s existing large rare earth reserves less commercially viable.
“In order to compete against that monopoly, the government needed to be fairly heavy handed in structuring a deal that would both get a magnet facility up and running and ensure that that magnet facility stays in operation and weathers the storm of Chinese price manipulation,” Zumwalt-Forbes said.
Beyond simply throwing money around, the federal government can also make long-term commitments that private companies and investors may not be willing or able to make.
“What this Department of Defense deal did is, yes, it provided much-needed cash. But it also gave them strategic certainty around getting that facility off the ground, which is almost more important,” Zumwalt-Forbes said.
“I think this won’t be the last creative critical mineral deal that we see coming out of the Department of Defense,” Zumwalt-Forbes added. They certainly are in pole position here, as opposed to the other agencies and prior administrations.”
On a new plan for an old site, tariffs on Canada, and the Grain Belt Express
Current conditions: Phoenix will “cool” to 108 degrees Fahrenheit today after hitting 118 degrees on Thursday, its hottest day of the year so far • An extreme wildfire warning is in place through the weekend in Scotland • University of Colorado forecasters decreased their outlook for the 2025 hurricane season to 16 named storms, eight hurricanes, and three major hurricanes after a quiet June and July.
President Trump threatened a 35% tariff on Canadian imports on Thursday, giving Prime Minister Mark Carney a deadline of August 1 before the levies would go into effect. The move follows months of on-again, off-again threats against Canada, with former Canadian Prime Minister Justin Trudeau having successfully staved off the tariffs during talks in February. Despite those earlier negotiations, Trump held firm on his 50% tariff on steel and aluminum, which will have significant implications for green manufacturing.
As my colleagues Matthew Zeitlin and Robinson Meyer have written, tariffs on Canadian imports will affect the flow of oil, minerals, and lumber, as well as possibly break automobile supply chains in the United States. It was unclear as of Thursday, however, whether Trump’s tariffs “would affect all Canadian goods, or if he would follow through,” The New York Times reports. The move follows Trump’s announcement this week of tariffs on several other significant trade partners like Japan and South Korea, as well as a 50% tariff on copper.
The long beleaguered Lava Ridge Wind Project, formally halted earlier this year by an executive order from President Trump, might have a second life as the site for small modular reactors, Idaho News 6 reports. Sawtooth Energy Development Corporation has proposed installing six small nuclear power generators on the former Lava Ridge grounds in Jerome County, Idaho, drawn to the site by the power transmission infrastructure that could connect the region to the Midpoint Substation and onto the rest of the Western U.S. The proposed SMR project would be significantly smaller in scale than Lava Ridge, which would have produced 1,000 megawatts of electricity on a 200,000-acre footprint, sitting instead on 40 acres and generating 462 megawatts, enough to power 400,000 homes.
Sawtooth Energy plans to hold four public meetings on the proposal beginning July 21. The Lava Ridge Wind Project had faced strong local opposition — we named it the No. 1 most at-risk project of the energy transition last fall — due in part to concerns about the visibility of the turbines from the Minidoka National Historic Site, the site of a Japanese internment camp.

Republican Senator Josh Hawley of Missouri said on social media Thursday that Energy Secretary Chris Wright had assured him that he will be “putting a stop to the Grain Belt Express green scam.” The Grain Belt Express is an 804-mile-long, $11 billion planned transmission line that would connect wind farms in Kansas to energy consumers in Missouri, Illinois, and Indiana, which has been nearing construction after “more than a decade of delays,” The New York Times reports. But earlier this month, Missouri Attorney General Andrew Bailey, a Republican, put in a request for the local public service commission to reconsider its approval, claiming that the project had overstated the number of jobs it would create and the cost savings for customers. Hawley has also been a vocal critic of the project and had asked the Energy Department to cancel its conditional loan guarantee for the transmission project.
New electric vehicles sold in Europe are significantly more environmentally friendly than gas cars, even when battery production is taken into consideration, according to a new study by the International Council on Clean Transportation. Per the report, EVs produce 73% less life-cycle greenhouse gas emissions than combustion engine cars, even considering production — a 24% improvement over 2021 estimates. The gains are also owed to the large share of renewable energy sources in Europe, and factor in that “cars sold today typically remain on the road for about 20 years, [and] continued improvement of the electricity mix will only widen the climate benefits of battery electric cars.” The gains are exclusive to battery electric cars, however; “other powertrains, including hybrids and plug-in hybrids, show only marginal or no progress in reducing their climate impacts,” the report found.

With the United Kingdom staring down its third heatwave in a month this week, a new study warns of dire consequences if homes and cities do not adapt to the new climate reality. According to researchers at the University College London and the London School of Hygiene and Tropical Medicine, heat-related deaths in England and Wales could rise 50-fold by the 2070s, jumping from a baseline of 634 deaths to 34,027 in a worst-case scenario of 4.3 degrees Celsius warming, a high-emissions pathway.
The report specifically cited the aging populations of England and Wales, as older people become more vulnerable to the impacts of extreme heat. Low adoption of air conditioning is also a factor: only 2% to 5% of English households use air conditioning, although that number may grow to 32% by 2050. “We can mitigate [the] severity” of the health impacts of heat “by reducing greenhouse gas emissions and with carefully planned adaptations, but we have to start now,” UCL researcher Clare Heaviside told Sky News.
This week, Centerville, Ohio, rolled out high-tech recycling trucks that will use AI to scan the contents of residents’ bins and flag when items have been improperly sorted. “Reducing contamination in our recycling system lowers processing costs and improves the overall efficiency of our collection,” City Manager Wayne Davis said in a statement about the AI pilot program, per the Dayton Daily News.
Or at least the team at Emerald AI is going to try.
Everyone’s worried about the ravenous energy needs of AI data centers, which the International Energy Agency projects will help catalyze nearly 4% growth in global electricity demand this year and next, hitting the U.S. power sector particularly hard. On Monday, the Department of Energy released a report adding fuel to that fire, warning that blackouts in the U.S. could become 100 times more common by 2030 in large part due to data centers for AI.
The report stirred controversy among clean energy advocates, who cast doubt on that topline number and thus the paper’s justification for a significant fossil fuel buildout. But no matter how the AI revolution is powered, there’s widespread agreement that it’s going to require major infrastructure development of some form or another.
Not so fast, says Emerald AI, which emerged from stealth last week with $24.5 million in seed funding led by Radical Ventures along with a slew of other big name backers, including Nvidia’s venture arm as well as former Secretary of State John Kerry, Google’s chief scientist Jeff Dean, and Kleiner Perkins chair John Doerr. The startup, founded and led by Orsted’s former chief strategy and innovation officer Varun Sivaram, was built to turn data centers from “grid liabilities into flexible assets” by slowing, pausing, or redirecting AI workloads during times of peak energy demand.
Research shows this type of data center load flexibility could unleash nearly 100 gigawatts of grid capacity — the equivalent of four or five Project Stargates and enough to power about 83 million U.S. homes for a year. Such adjustments, Sivaram told me, would be necessary for only about 0.5% of a data center’s total operating time, a fragment so tiny that he says it renders any resulting training or operating performance dips for AI models essentially negligible.
As impressive as that hypothetical potential is, whether a software product can actually reduce the pressures facing the grid is a high stakes question. The U.S. urgently needs enough energy to serve that data center growth, both to ensure its economic competitiveness and to keep electricity bills affordable for Americans. If an algorithm could help alleviate even some of the urgency of an unprecedented buildout of power plants and transmission infrastructure, well, that’d be a big deal.
While Emerald AI will by no means negate the need to expand and upgrade our energy system, Sivaram told me, the software alone “materially changes the build out needs to meet massive demand expansion,” he said. “It unleashes energy abundance using our existing system.”
Grand as that sounds, the fundamental idea is nothing new. It’s the same concept as a virtual power plant, which coordinates distributed energy resources such as rooftop solar panels, smart thermostats, and electric vehicles to ramp energy supply either up or down in accordance with the grid’s needs.
Adoption of VPPs has lagged far behind their technical potential, however. That’s due to a whole host of policy, regulatory, and market barriers such as a lack of state and utility-level rules around payment structures, insufficient participation incentives for customers and utilities, and limited access to wholesale electricity markets. These programs also depend on widespread customer opt-in to make a real impact on the grid.
“It’s really hard to aggregate enough Nest thermostats to make any kind of dent,”” Sivaram told me. Data centers are different, he said, simply because “they’re enormous, they’re a small city.” They’re also, by nature, virtually controllable and often already interconnected if they’re owned by the same company. Sivaram thinks the potential of flexible data center loads is so promising and the assets themselves so valuable that governments and utilities will opt to organize “bespoke arrangements for data centers to provide their services.”
Sivaram told me he’s also optimistic that utilities will offer data center operators with flexible loads the option to skip the ever-growing interconnection queue, helping hyperscalers get online and turn a profit more quickly.
The potential to jump the queue is not something that utilities have formally advertised as an option, however, although there appears to be growing interest in the idea. An incentive like this will be core to making Emerald AI’s business case work, transmission advocate and president of Grid Strategies Rob Gramlich told me.
Data center developers are spending billions every year on the semiconductor chips powering their AI models, so the typical demand response value proposition — earn a small sum by turning off appliances when the grid is strained — doesn’t apply here. “There’s just not anywhere near enough money in that for a hyperscaler to say, Oh yeah, I’m gonna not run my Nvidia chips for a while to make $200 a megawatt hour. That’s peanuts compared to the bazillions [they] just spent,” Gramlich explained.
For Emerald AI to make a real dent in energy supply and blunt the need for an immediate and enormous grid buildout, a significant number of data center operators will have to adopt the platform. That’s where the partnership with Nvidia comes in handy, Sivaram told me, as the startup is “working with them on the reference architecture” for future AI data centers. “The goal is for all [data centers] to be potentially flexible in the future because there will be a standard reference design,” Sivaram said.
Whether or not data centers will go all in on Nvidia’s design remains to be seen, of course. Hyperscalers have not typically thought of data centers as a flexible asset. Right now, Gramlich said, most are still in the mindset that they need to be operating all 8,760 hours of the year to reach their performance targets.
“Two or three years ago, when we first noticed the surge in AI-driven demand, I talked to every hyperscaler about how flexible they thought they could be, because it seemed intuitive that machine learning might be more flexible than search and streaming,” Gramlich told me. By and large, the response was that while these companies might be interested in exploring flexibility “potentially, maybe, someday,” they were mostly focused on their mandate to get huge amounts of gigawatts online, with little time to explore new data center models.
“Even the ones that are talking about flexibility now, in terms of what they’re actually doing in the market today, they all are demanding 8,760 [hours of operation per year],” Gramlich told me.
Emerald AI is well aware that its business depends on proving to hyperscalers that a degree of flexibility won’t materially impact their operations. Last week, the startup released the results of a pilot demonstration that it ran at an Oracle data center in Phoenix, which proved it was able to reduce power consumption by 25% for three hours during a period of grid stress while still “assuring acceptable customer performance for AI workloads.”
It achieved this by categorizing specific AI tasks — think everything from model training and fine tuning to conversations with chatbots — from high to low priority, indicating the degree to which operations could be slowed while still meeting Oracle’s performance targets. Now, Emerald AI is planning additional, larger-scale demonstrations to showcase its capacity to handle more complex scenarios, such as responding to unexpected grid emergencies.
As transmission planners and hyperscalers alike wait to see more proof validating Emerald AI’s vision of the future, Sivaram is careful to note that his company is not advocating for a halt to energy system expansion. In an increasingly electrified economy, expanding and upgrading the grid will be essential — even if every data center in the world has a flexible load profile.
’We should be building a nationwide transmission system. We should be building out generation. We should be doing grid modernization with grid enhancing technologies,” Sivaram told me. “We just don’t need to overdo it. We don’t need the particularly massive projections that you’re seeing that are going to cause your grandmother’s electricity rates to spike. We can avoid that.”
