In an exclusive interview, the White House advisor tells Heatmap that rules around hydrogen, manufacturing, and aviation fuel are weeks away and offers a window into his thinking.

The rules governing virtually all of the remaining policies in President Joe Biden’s climate law — including some of its most important and generous provisions — will come out in the next several weeks, signaling a new era in the law’s implementation, a senior White House advisor told Heatmap in an exclusive interview.
Speaking on the sidelines of the United Nations climate conference in Dubai, the advisor John Podesta said that the Treasury Department will publish rules governing some of the law’s biggest remaining subsidies by the end of the year. The former White House chief of staff and veteran political strategist also offered a window into his thinking about the implementation of the policies, which he has been charged with overseeing since last year.
The upcoming subsidies include some of the most important tax credits in the law. They are aimed at boosting climate-friendly aviation fuel, low-carbon hydrogen, and new factories building EVs and other clean-energy equipment. Podesta said that guidance for all three tax credits will be published by the end of the year. When they are released, every active subsidy in the Inflation Reduction Act will be usable and open for business.

Podesta has spent much of the past year immersed in the tax code, the site of many of the law’s most sweeping policies. On Sunday, he walked Heatmap through his thought process behind some of the biggest unreleased rules.
He expressed particular worry about the rules governing “green hydrogen,” which is produced by using electricity to separate water into oxygen and hydrogen.
“This has been the most challenging piece of policy that we’ve had to contend with” while implementing the IRA, Podesta said.
Many energy scholars believe that hydrogen, which produces no climate pollution when burned, could potentially replace fossil fuels in many sectors. But the IRA’s tax credit is so generous — providing companies with up to $3 for every kilogram of hydrogen produced — that some experts have argued that exceptionally strong rules must govern it, so as to make sure it actually serves to reduce emissions.
Hydrogen “has the potential to pay enormous dividends in 2030 and 2040 in reducing emissions from the industrial sector, from heavy duty transportation, et cetera,” Podesta said. “But at the same time, not do it in a way that lacks environmental integrity.”
He described the White House’s work as trying to balance between two bad outcomes: On the one hand, it could stifle the production of green hydrogen so much that “blue hydrogen,” produced using natural gas and carbon capture technology, dominates; on the other, it could boost green hydrogen so much that it distorts electricity markets nationwide.
“We could kind of blow it in either direction, I think,” Podesta said. “We can either be in a context in which we’re not really driving deployment, and therefore driving innovation, particularly on the electrolyzer side, so that we end up kind of filling the gap with a lot of blue hydrogen rather than green hydrogen. On the other hand, if we go the other way, we sort of blow emissions on the grid.”
The big question confronting the Treasury Department is how to measure climate pollution produced from the electricity used to create green hydrogen. One sticking point is whether hydrogen producers will be allowed to buy power from existing zero-carbon power plants, like nuclear power plants and hydroelectric dams. That could be a boon for Constellation Energy, the country’s largest owner of nuclear facilities.
But researchers at Princeton and MIT have argued that if hydrogen companies aren’t required to bring new clean energy resources onto the grid to account for the power that they’re using to make hydrogen, then they will inadvertently increase climate pollution. That is because if a nuclear reactor stops serving homes and businesses and starts powering hydrogen production, then natural gas and coal plants will likely produce electricity to fill the gap, at least in the near term.
“You could see a world where all of the U.S. nukes pivot to supplying electrolyzers and just print money that way,” Dan Esposito, a policy analyst at the think tank Energy Innovation, told Heatmap earlier this year. “There’s just a lot of layers to how bad this can get.”
But speaking in Dubai, Podesta appeared to reject some of these more extreme scenarios.
“I think a lot of the model runs just have assumptions that are very, very — you know,” Podesta said. “Like, all nuclear power plants are not going to stop sending power to the grid and start making hydrogen. That is not going to happen. I guarantee you that.”
“So you can have an upside estimate of what that means, but to what end?” he added. “It’s tricky, because the [hydrogen] industry essentially does not exist. So we're making judgment calls about what we need to do to get the green side of the industry really going, in this decade.”
Podesta was more sanguine about the other two tax credits. “We’ve got a game plan on [the sustainable aviation fuel tax credit], and I think it’s going to be fine,” he said, although he added that it would require updating a key Department of Energy model that governs the policy.
“We’ll be able to both stimulate production but also create environmental integrity in that program,” he said.
That policy is expected in the middle of December. The last remaining tax credit, which will subsidize new factories in America to build clean-energy equipment, will be out next week, a Treasury Department spokesperson told Heatmap.
Once rules are written for those three programs, virtually all of the active subsidies in the Inflation Reduction Act will be ready to use. The IRA contains another set of subsidies — “technology-neutral” tax credits that will boost zero-carbon power generation until the country hits certain decarbonization goals — that the Treasury Department has not yet written rules for. But that program will not go into effect until 2025.
Starting on January 1, a new era will begin in the law’s implementation, as the government moves to award the climate law’s more than $100 billion in grants, Podesta said. “It’s going from, ‘This money is available, please apply,’ to, ‘Here’s the money, go put it to work,’” Podesta said.
In the spring, the Greenhouse Gas Reduction Fund — a new $27 billion in-house investment fund created at the Environmental Protection Agency — will begin distributing its funding, he added.
“I think that could be very, very powerful and important, not just from the perspective of reducing costs for consumers and reducing emissions, but in terms of the goal of deploying against the justice part of the president’s agenda,” he said. “That’s really where you can see the community impact happen.”

Flames have erupted in the “Blue Zone” at the United Nations Climate Conference in Brazil.
A literal fire has erupted in the middle of the United Nations conference devoted to stopping the planet from burning.
The timing couldn’t be worse. Today is the second to last day of the annual climate meeting known as COP30, taking place on the edge of the Amazon rainforest in Belém, Brazil. Delegates are in the midst of heated negotiations over a final decision text on the points of agreement this session.
A number of big questions remain up in the air, including how countries will address the fact that their national plans to cut emissions will fail to keep warming “well under 2 degrees Celsius,” the target they supported in the 2015 Paris Agreement. They are striving to reach agreement on a list of “indicators,” or metrics by which to measure progress on adaptation. Brazil has led a push for the conference to mandate the creation of a global roadmap off of fossil fuels. Some 80 countries support the idea, but it’s still highly uncertain whether or how it will make its way into the final text.
Just after 2:00 p.m. Belém time, 12 p.m. Eastern, I was in the middle of arranging an interview with a source at the conference when I got the following message:
“We've been evacuated due to a fire- not exactly sure how the day is going to continue.”
The fire is in the conference’s “Blue Zone,” an area restricted to delegates, world leaders, accredited media, and officially designated “observers” of the negotiations. This is where all of the official negotiations, side events, and meetings take place, as opposed to the “Green Zone,” which is open to the public, and houses pavilions and events for non-governmental organizations, business groups, and civil society groups.
It is not yet clear what the cause of the fire was or how it will affect the home sprint of the conference.
Outside of the venue, a light rain was falling.

The Trump administration on Wednesday proposed significant new limits on federal protection under the Endangered Species Act. A series of four tweaked rules would reset how the bedrock environmental law to prevent animal and plant extinctions could be used to block oil drilling, logging, and mining in habitats for endangered wildlife, The New York Times reported. Among the most contentious is a proposal to allow the government to consider economic factors before determining whether to list a species as endangered. Another change would raise the bar for enacting protections based on predicted future threats such as climate change. “This administration is restoring the Endangered Species Act to its original intent, protecting species through clear, consistent and lawful standards that also respect the livelihoods of Americans who depend on our land and resources,” Secretary of the Interior Doug Burgum said in a statement.
In Congress, meanwhile, bipartisan reforms to make federal permitting easier are advancing. Representative Scott Peters, the Democrat in charge of the permitting negotiations, called the SPEED Act introduced by Representative Bruce Westerman, the Republican chairman of the Natural Resources Committee, a “huge step forward,” according to a post on X from Politico reporter Josh Siegel. But Peters hinted that getting the legislation to the finish line would require the executive branch to provide “permit certainty,” a thinly-veiled reference to Democrats’ demand that the Trump administration ease off its so-called “total war on wind” turbines.
In World Cup soccer, Turkey hasn’t faced Australia in more than a decade. But the two countries went head to head in the competition to host next year’s United Nations climate summit, COP31. Turkey won, Bloomberg reported last night. Australia’s defeat is a blow not just to Canberra but to those who had hoped a summit Down Under would set the stage for an “island COP.” The pre-conference leaders’ gathering is set to take place on an as-yet-unnamed Pacific island, which had raised hopes that the next confab could put fresh emphasis on the concerns of low-lying nations facing sea-level rise.
More than a dozen states where data centers are popping up could face electric power emergencies under extreme conditions this winter, a grid security watchdog warned this week, E&E News reported. The North American Electric Reliability Corporation listed New England, the Carolinas, most of Texas, and the Pacific Northwest among the most threatened regions. If those emergencies take place, the grid operators would need to import more electricity from other regions and seek voluntary power cutbacks from customers before resorting to rotating blackouts.

The United States is on the cusp of restarting a permanently shuttered atomic power plant for the first time. But anti-nuclear groups are making a last-ditch effort to block the revival. In a complaint filed Monday in the U.S. District court for the Western District of Michigan, a trio of activist organizations — Beyond Nuclear, Don’t Waste Michigan, and Michigan Safe Energy Future — argued that the plant should never have received regulatory approval for a restart. As I wrote in this newsletter at the time, the Nuclear Regulatory Commission granted plant owner Holtec International permission to go ahead with the restoration in July. Last month, the company — best known for manufacturing waste storage vessels and decommissioning defunct plants — received a shipment of fuel for the single-reactor station, as I reported here. While the opponents are asking the federal judge to intervene, state lawmakers in Michigan are considering new subsidies for nuclear power, Bridge Michigan reported.
Further north along Michigan’s western coastline, a coal-fired power plant set to close down in May got another extension from the Trump administration. In an order signed Tuesday, Secretary of Energy Chris Wright renewed his direction to utility Consumers Energy to hold off on shutting down the facility, which the administration deemed necessary to stave off blackouts. The latest order, Michigan Advance noted, extends until February 17, 2026. President Donald Trump’s efforts to prop up the coal industry haven’t gone so well elsewhere. As Heatmap’s Matthew Zeitlin reported last week, coal-fired stations keep breaking down, with equipment breaking at more than twice the rate of wind turbines.
Matthew had another timely story out yesterday: Members of the PJM Interconnection’s voting base of advisers met Wednesday to consider a dozen different proposals for how to bring more data centers online put forward by data center companies, transmission developers, utilities, state lawmakers, advocates, PJM’s market monitor, and PJM itself. None passed. “There was no winner here,” PJM chief executive Manu Asthana told the meeting following the announcement of the vote tallies. There was, however, “a lot of information in these votes,” he added. “We’re going to study them closely.” The grid operator still aims to get something to federal regulators by the end of the year.
Here’s a gruesome protocol that apparently exists when a toothed whale washes up. Federal officials arrived on Nantucket on Wednesday afternoon to remove a beached sperm whale’s jaw. Per the Nantucket Current: “This is being done to prevent any theft of its teeth, which are illegal to take and possess. The Environmental Police will take the jaw off-island.”
Members of the nation’s largest grid couldn’t agree on a recommendation for how to deal with the surge of incoming demand.
The members of PJM Interconnection, the country’s largest electricity market, held an advisory vote Wednesday to help decide how the grid operator should handle the tidal wave of incoming demand from data centers. Twelve proposals were put forward by data center companies, transmission companies, power companies, utilities, state legislators, advocates, PJM’s market monitor, and PJM itself.
None of them passed.
“There was no winner here,” PJM chief executive Manu Asthana told the meeting following the announcement of the vote tallies. There was, however, “a lot of information in these votes,” he added. “We’re going to study them closely.”
The PJM board was always going to make the final decision on what it would submit to federal regulators, and will try to get something to the Federal Energy Regulatory Commission by the end of the year, Asthana said — just before he plans to step down as CEO.
“PJM opened this conversation about the integration of large loads and greatly appreciates our stakeholders for their contributions to this effort. The stakeholder process produced many thoughtful proposals, some of which were introduced late in the process and require additional development,” a PJM spokesperson said in a statement. “This vote is advisory to PJM’s independent Board. The Board can and does expect to act on large load additions to the system and will make its decision known in the next few weeks.”
The surge in data center development — actual and planned — has thrown the 13-state PJM Interconnection into a crisis, with utility bills rising across the network due to the billions of dollars in payments required to cover the additional costs.
Those rising bills have led to cries of frustration from across the PJM member states — and from inside the house.
“The current supply of capacity in PJM is not adequate to meet the demand from large data center loads and will not be adequate in the foreseeable future,” PJM’s independent market monitor wrote in a memo earlier this month. “Customers are already bearing billions of dollars in higher costs as a direct result of existing and forecast data center load,” it said in a quarterly report released just a few days letter, pegging the added charges to ensure that generators will be available in times of grid stress due to data center development at over $16 billion.
PJM’s initial proposal to deal with the data center swell would have created a category for new large sources of demand on the system to interconnect without the backing of capacity; in return, they’d agree to have their power supply curtailed when demand got too high. The proposal provoked outrage from just about everyone involved in PJM, including data center developers and analysts who were open to flexibility in general, who said that the grid operator was overstepping its responsibilities.
PJM’s subsequent proposal would allow for voluntary participation in a curtailment program, but was lambasted by environmental groups like Evergreen Collaborative for not having “any semblance of ambition.” PJM’s own market monitor said that voluntary schemes to curtail power “are not equivalent to new generation,” and that instead data centers should “be required to bring their own new generation” — essentially to match their own demand with new supply.
A coalition of environmental groups, including the Natural Resources Defence Council and state legislators in PJM, said in their proposal that data centers should be required to bring their own capacity — crucially counting demand response (being paid to curtail power) as a source of capacity.
“The growth of data centers is colliding with the reality of the power grid,” Tom Rutigliano, who works on grid issues for the Natural Resources Defense Council, said in a statement. “PJM members weren’t able to see past their commercial interests and solve a critical reliability threat. Now the board will need to stand up and make some hard decisions.”
Those decisions will come without any consensus from members about what to do next.
“Just because none of these passed doesn’t mean that the board will not act,” David Mills, the chairman of PJM’s board of managers, said at the conclusion of the meeting. “We will make our best efforts to put something together that will address the issues.”
