At least for the foreseeable future. But is the Manchin-Barrasso bill actually worth it?
So … is the permitting reform bill any good or not?
Earlier this year, Senators Joe Manchin of West Virginia and John Barrasso of Wyoming proposed a bill that would change federal environmental rules so as to spur a buildout of new energy infrastructure around the country.
Their proposal would have loosened rules for oil and gas drilling and exporting while changing federal law to encourage the construction of more clean energy.
These renewables-friendly changes included creating a new legal regime that would push utilities and grid operators to build significantly more long-distance power lines, triggering a nationwide boost to renewable resources. They would also have changed the regulations governing geothermal power generation, allowing new enhanced geothermal wells to play by the same federal rules that bind oil and gas.
The legislation was announced in July and then … nothing happened.
Now it seems likely to come back. Congress is eyeing its final agenda items for the year, and permitting reform is one of them. Representative Bruce Westerman, a Republican who chairs the House Committee on Natural Resources, is currently said to be revamping Manchin and Barrasso’s proposal to include reforms to the National Environmental Policy Act, a bedrock law that guides the process — but not the outcome — of virtually every major decision that the federal government makes and requires it to study the environmental impact of its policies.
We don’t know what those changes will look like yet, though they’ll have to come soon — the new Congress gets sworn in in just a few weeks. Which means lawmakers will have to get the proposed changes, process them, and decide whether to vote for them in a very short period of time — just a few days.
So during this liminal period, then, I wanted to take a moment to look at the other parts of the bill. Earlier this year, we got a sense of what the bill’s quantitative effects might be. They suggest that the legislation — at least in the initial version proposed by Manchin and Barrasso — could very well help cut U.S. emissions, or at least leave them flat. But after that? It starts to get complicated.
Republicans have long pushed for changes to the federal government’s permitting regime.
But in recent years, Democrats — who hope to prompt a national surge of clean energy construction — have come aboard too. The Biden administration, frustrated that some parts of the Inflation Reduction Act and Bipartisan Infrastructure Law haven’t resulted in the large-scale projects they hoped for, has come to back permitting reform explicitly, although they have not endorsed Manchin and Barrasso’s bill.
“The president has been clear … that we believe permitting reform should pass on a bipartisan basis — and that we believe permitting needs to be optimized for building out a clean energy economy,” John Podesta, a White House senior advisor who is now the country’s top climate diplomat, said in a speech last year.
The White House’s support of bipartisan permitting reform is more than just posturing: Because of Senate math, any changes to the country’s permitting laws almost certainly must be bipartisan. Until a bare majority of Democratic senators exists to kill the legislative filibuster, it will take a vote of at least 60 senators — a so-called supermajority — to alter most pre-existing federal legislation.
So the question, then, is: Is this attempt at permitting reform worth passing? Is this package of fossil fuel concessions and clean energy incentives likely to reduce emissions more than it increases them?
I won’t try to answer that question comprehensively today, and we can’t even answer it fully until we know the scope of Westerman’s changes. But I do want to share an analysis from the center-left think tank Third Way and other researchers that suggests that the answer is “yes.”
This analysis, released in September, argues that Manchin and Barrasso’s bill would modestly increase emissions by encouraging more oil and gas drilling on federal lands. But that increase would likely be dwarfed by a large decrease in emissions prompted by building out the country’s electricity transmission grid.
More specifically, it finds that while the pro-fossil fuel provisions could raise global climate pollution by as much as 6.1 billion metric tons by 2050, the bill’s support for transmission could cut emissions by as much as 15.7 billion metric tons in that time (although the final number, as you’ll see, is a very high end estimate). That’s because, as I’ve written before, building the grid will allow for more renewable, geothermal, and other forms of zero-carbon electricity generation to get built. And the country can only reduce emissions by building more zero-carbon electricity.
Some of those emissions increases from oil and gas are now likely to occur whether or not the bill passes — the Trump administration will encourage fossil fuel extraction and export far beyond what a Harris administration would have done.
But even in a more conservative scenario, the transmission provisions would still cut emissions by 6.5 billion metric tons by 2050, Third Way’s synthesis says. That would mean — when compared to the pro-fossil policies — that the bill has a much more modest effect overall, cutting emissions by just over 400 million tons through 2050.
These aren’t the only numbers out there. An analysis by Jeremy Symons, the former vice president of public affairs at the Environmental Defense Fund, argues that the bill’s loosening of some Biden-era restrictions on liquified natural gas export terminals will result in a tremendous LNG boom. He asserts that the bill’s LNG provisions could increase global emissions by 8.5 to 11 gigatons; his analysis, however, draws heavily from a controversial, initially erroneous, and now updated study from the Cornell ecologist Robert Howarth that contends American natural gas is far worse for the climate than coal.
Third Way did not include Symons’ study in its analysis. Instead, it cites a different study led by the Princeton professor Jesse Jenkins (with whom I cohost Heatmap’s Shift Key podcast) that uses natural-gas emissions estimates more in line with the broader scholarly literature. That modeling study indicates that the LNG provisions in the Manchin-Barrasso bill could increase emissions by as much as 3.3 gigatons — or decrease them by 2.4 gigatons.
I’m not going to get more into the LNG question in this story. And it’s somewhat less important than it was earlier this year because Trump administration is likely to approve as many LNG export terminals as it can. (That doesn’t mean those terminals will get built: Right now, a dozen LNG terminals have been approved but not built due to a lack of global demand for more LNG.) Instead, I want to dive into two specific provisions in the bill — on oil and gas leasing and transmission — that reveal the broader challenges of trying to speak concretely about this proposal.
By far the most climate-friendly provisions in EPRA concern its support of long-distance electricity transmission. As I’ve covered before, the lack of electricity transmission is now one of the biggest barriers to building new wind, solar, and other clean energy in the United States; the construction of new wind farms, in particular, seems to be slowing down because of a lack of available power lines to carry their electrons.
Manchin and Barrasso’s proposal aims to build more transmission largely by granting new powers to the Federal Energy Regulatory Commission, the independent agency that oversees the country’s power grids. EPRA would, for instance, allow FERC to step in and approve transmission lines that are “in the national interest” if a state has not acted on a given project within a year. The law also clarifies who should pay for a new power line, encoding the idea that customers who benefit from a line should pay for it. And it lets FERC approve payments from developers to the communities where new transmission infrastructure gets built, potentially smoothing approvals at the local level.
The bill also instructs FERC to write a rule that will require each part of the country to build a minimal amount of power lines that allow regions to exchange power with their neighbors. This measure — meant to spur new “interregional” transmission infrastructure — aims to knit the national grid more closely together and lower power costs on average.
How much would these policies reduce national emissions? The truth is, that’s extremely difficult to model. “There’s nothing in the EPRA that says, Thou shalt build this much transmission,” Charles Teplin, a grid expert at the think tank RMI, told me.
Instead, the bill aims to kick off a process that will result in more transmission getting built. That transmission should — in theory — bring more renewables online. But what will the size of that buildout be, and how many emissions will those renewables displace?
Answering these questions requires, again, estimating the uncertain. To come up with a reasonable, conservative figure to represent the amount of regional transmission that might get built under the new FERC process, they looked at what happened when a similar process was overseen by the Midwest’s grid. Then they rounded down that figure significantly.
Teplin and his colleagues also assumed that some big power lines that have already been proposed nationwide — roughly 15 gigawatts, to be exact — will get completed faster because of these new laws, so their analysis starts to bring them online by 2029. One only need look at the nearly two-decade saga of SunZia, a large power line that crosses New Mexico and Arizona, to see how long it can take to finish those projects today.
Under those assumptions, the law should more than double the rate of America’s transmission buildout, Teplin and his team estimated. Right now, the country builds perhaps 1 gigawatt of new transmission lines every year; under their assumptions, that would leap to 2 to 4 gigawatts a year.
So how many emissions would these new lines avoid? Using a report published by Grid Strategies, a power sector consulting firm that advocates for more transmission, Teplin and his colleagues estimate that each “gigawatt-mile” of new transmission will let operators add about 32 gigawatts of solar and wind to the grid each year. (This suggests that, most of the time, the lines would run at about 30% of capacity.)
Finally, the team assumed that electricity from these new renewable projects will replace power from natural gas plants. That, too, is an approximation: Some of those new wind and solar farms will drive out coal plants; others might replace non-emitting resources like nuclear or hydroelectric dams; but in general they will reduce gas burning.
When you put all those figures together, RMI’s analysis suggests that the legislation could build roughly twice as much new clean energy generation by 2050 as exists in all fossil-fuel power plants today. These new resources would help avoid about 6.5 gigatons of greenhouse gas emissions by the middle of the century.
That may seem like a big number — but Third Way was actually able to reach an even larger estimate. Teplin and his team didn’t try to differentiate, for instance, between the effects of a recent FERC order, which requires utilities to build more transmission within regions, and the proposed Manchin-Barrasso bill, which shores up the legality of that FERC order and would also induce utilities to build more power lines between regions. Some legal experts argue that the recent FERC order will be on shaky ground if the Manchin-Barrasso bill doesn’t pass; others say it’s stable enough as-is.
If you assume that courts will kill the FERC order unless Congress acts, then that should raise your estimate of what Manchin-Barrasso might do. That’s essentially what Third Way did — by giving the bill more credit for the resulting regional transmission buildout, they say that its carbon upside could be as large as 15.7 gigatons over the next 25 years. I’m not sure I would be that aggressive, but I think the transmission provisions would likely initiate a big buildout of renewables.
The Manchin-Barrasso bill contains a number of provisions that aim to increase the leasing of federal land for oil and gas drilling. One set requires that the Interior Department must offer a minimum amount of acres every year for oil and gas leasing. It also says that the land offered must be land that oil and gas companies actually want to lease.
This would address one of Republicans’ biggest objections to how the Biden administration has handled oil and gas extraction on federally owned land. As part of the Inflation Reduction Act, Manchin required that the government offer a minimum amount of oil and gas acreage for every acre of public land it leased to wind and solar developers. But Republicans have accused the Biden administration of getting around this rule by, in essence, offering useless or otherwise undesirable land.
(This concession, I should add, is now essentially moot until 2029, as the Trump administration will hasten to nominate the parcels that oil and gas companies are most excited to drill on. But it could bind a future Democratic administration, requiring them to offer good parcels for oil and gas leasing at the same time that they offer federal land for renewable development.)
The bill would also change some of the rules around the drilling allowed on the borders of federally owned land. Under the Manchin-Barrasso bill, companies could drill a vertical well on privately owned land, then extend it horizontally underground into federal land to extract oil or gas.
These provisions, too, are difficult to model. Much like the transmission proposal, they won’t lead to a guaranteed amount of drilling (although they will essentially produce a minimumamount of fossil fuel leasing). Nor will they substantially change the drilling that happens under Donald Trump or a future Republican president because any fossil fuel-loving administration is already free to go much further than these provisions would require them to.
To estimate the emissions impact of these provisions, the think tank Resources for the Future first tried to draw some error bars around their analysis. As a worst-case scenario, analysts modeled what would happen if the onshore drilling that happened during the Trump administration occurred every year from 2025 to 2050. Under this “Trump forever” scenario, emissions increase about 2.1 gigatons from 2025 to 2050. Under a less dire scenario, they would increase by about 0.6 gigatons during the same period.
These estimates almost certainly exceed what EPRA would actually do, Kevin Rennert, the director of RFF’s federal climate policy initiative, told me.
“None of the provisions would require the levels of leasing that we’re analyzing in the high-leasing scenario,” he said. “It’s clear [that the model is] a high upper bound on what EPRA itself would drive.” The provisions in the Manchin-Barrasso bill, in other words, are aimed much more at putting a floor under a future Democratic administration than they are raising a ceiling for a future Republican administration.
(Over all these discussions hangs a curious question about drilling for oil and gas on public land: How important is it, really? But that’s a question for another time.)
How you feel about this reform effort ultimately depends on how you feel about gambling. Is it worth hamstringing a future Democratic president’s ability to hem in oil production in exchange for unleashing a wave of new transmission under the Trump administration? How much do you weigh building more renewables versus selling more fossil fuels to the world?
Trump’s victory last month also changes the calculus. His administration will increase onshore oil and gas leasing regardless of whether this bill passes or not. He will stop the Energy Department’s effort to slow down the construction of LNG terminals and approve a new wave of projects. All of the bill’s support for fossil fuels, in other words, would be moot — Trump will do that stuff anyway. So the question becomes whether the bill’s support for new transmission infrastructure 1) actually builds new power lines, and 2) provides a useful tailwind for renewables and clean energy during what would otherwise be a difficult four years.
You can go in almost endless loops through the politics here. Given Trump’s antipathy toward renewables, why should we expect his administration to allow a transmission buildout in the first place, regardless of what Congress says? In which case, maybe the bill isn’t worth it. But on the other hand, maybe it is — since Trump’s going to do everything he can to juice fossil fuels and fight renewables, why not pass the bill and give power system regulators in blue and purple states an extra tool to juice clean energy construction? And hey, given Trump’s friendliness toward the AI boom, maybe he’ll wind up having to build more transmission just to service data centers.
We can’t make that political call quite yet. Until we know exactly how Westerman’s addition to the legislation would change NEPA, it’s hard to say where lawmakers should come down. But what’s clear is that this may be Congress’s last chance to deal with permitting reform for a while. Next year, the Republican majority is likely to be focused on tax cuts, and it’s not even clear that the reconciliation process would allow for changing permitting law. “We’re pretty pessimistic that you could include anything on permitting or transmission or any of these other things in the reconciliation process,” Devin Hartman, a policy director at the center-right think tank the R Street Institute, told Heatmap this week.
So this is it for permitting reform — it’s now or never for this set of changes. In a year full of surprises for climate and environmental law, we may yet get one more.

Jesse teaches Rob the basics of energy, power, and what it all has to do with the grid.
What is the difference between energy and power? How does the power grid work? And what’s the difference between a megawatt and a megawatt-hour?
On this week’s episode, we answer those questions and many, many more. This is the start of a new series: Shift Key Summer School. It’s a series of introductory “lecture conversations” meant to cover the basics of energy and the power grid for listeners of every experience level and background. In less than an hour, we try to get you up to speed on how to think about energy, power, horsepower, volts, amps, and what uses (approximately) 1 watt-hour, 1 kilowatt-hour, 1 megawatt-hour, and 1 gigawatt-hour.
Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

Here is an excerpt from our conversation:
Jesse Jenkins: Let’s start with the joule. The joule is the SI unit for both work and energy. And the basic definition of energy is the ability to do work — not work in a job, but like work in the physics sense, meaning we are moving or displacing an object around. So a joule is defined as 1 newton-meter, among other things. It has an electrical equivalent, too. A newton is a unit of force, and force is accelerating a mass, from basic physics, over some distance in this case. So 1 meter of distance.
So we can break that down further, right? And we can describe the newton as 1 kilogram accelerated at 1 meter per second, squared. And then the work part is over a distance of one meter. So that kind of gives us a sense of something you feel. A kilogram, right, that’s 2.2 pounds. I don’t know, it’s like … I’m trying to think of something in my life that weighs a kilogram. Rob, can you think of something? A couple pounds of food, I guess. A liter of water weighs a kilogram by definition, as well. So if you’ve got like a liter bottle of soda, there’s your kilogram.
Then I want to move it over a meter. So I have a distance I’m displacing it. And then the question is, how fast do I want to do that? How quickly do I want to accelerate that movement? And that’s the acceleration part. And so from there, you kind of get a physical sense of this. If something requires more energy, if I’m moving more mass around, or if I’m moving that mass over a longer distance — 1 meter versus 100 meters versus a kilometer, right? — or if I want to accelerate that mass faster over that distance, so zero to 60 in three seconds versus zero to 60 in 10 seconds in your car, that’s going to take more energy.
Robinson Meyer: I am looking up what weighs … Oh, here we go: A 13-inch MacBook Air weighs about, a little more than a kilogram.
Jenkins: So your laptop. If you want to throw your laptop over a meter, accelerating at a pace of 1 meter per second, squared …
Meyer: That’s about a joule.
Jenkins: … that’s about a joule.

If the Senate reconciliation bill gets enacted as written, you’ve got about 92 days left to seal the deal.
If you were thinking about buying or leasing an electric vehicle at some point, you should probably get on it like, right now. Because while it is not guaranteed that the House will approve the budget reconciliation bill that cleared the Senate Tuesday, it is highly likely. Assuming the bill as it’s currently written becomes law, EV tax credits will be gone as of October 1.
The Senate bill guts the subsidies for consumer purchases of electric vehicles, a longstanding goal of the Trump administration. Specifically, it would scrap the 30D tax credit by September 30 of this year, a harsher cut-off than the version of the bill that passed the House, which would have axed the credit by the end of 2025 except for automakers that had sold fewer than 200,000 electric vehicles. The credit as it exists now is worth up to $7,500 for cars with an MSRP below $55,000 (and trucks and sports utility vehicles under $80,000), and, under the Inflation Reduction Act, would have lasted through the end of 2032. The Senate bill also axes the $4,000 used EV tax credit at the end of September.
“Long story short, the credits under the current legislation are only going to be on the books through the end of September,” Corey Cantor, the research director of the Zero Emission Transportation Association, told me. “Now is definitely a good time, if you’re interested in an EV, to look at the market.”
The Senate applied the same strict timeline to credits for clean commercial vehicles, both new and used. For home EV chargers, the tax credit will now expire at the end of June next year.
While EVs were on the road well before the 2022 passage of the Inflation Reduction Act, what the new tax credit did was help build out a truly domestic electric vehicle market, Cantor said. “You have a bunch of refreshed EV models from major automakers,” Cantor told me, including “more affordable models in different segments, and many of them qualify for the credit.”
These include cars produceddomestically by Kia,Hyundai, and Chevrolet. But of course, the biggest winner from the credit is Tesla, whose Model Y was the best-selling car in the world in 2023.
Tesla shares were down over 5.5% in Tuesday afternoon trading, though not just because of Congress. JPMorgan also released an analyst report Monday arguing that the decline in sales seen in the first quarter would accelerate in the second quarter. President Trump, with whom Tesla CEO Elon Musk had an extremely public falling out last month, suggested on social media Monday night that the government efficiency department Musk himself formerly led should “take a good, hard, look” at the subsidies Musk receives across his many businesses. Trump also said that he would “take a look” at Musk’s United States citizenship in response to reporters’ questions about it.
Cantor told me that he expects a surge of consumer attention to the EV market if the bill passes in its current form. “You’ve seen more customers pull their purchase ahead” when subsidies cut-offs are imminent, he said.
But overall, the end of the subsidy is likely to reduce EV sales from their previously expected levels.
Harvard researchers have estimated that the termination of the EV tax credit “would cut the EV share of new vehicle sales in 2030 by 6.0 percentage points,” from 48% of new sales by 2030 to 42%. Combined with other Trump initiatives such as terminating the National Electric Vehicle Infrastructure program for publicly funded chargers (currently being litigated) and eliminating California’s waiver under the Clean Air Act that allowed it to set tighter vehicle emissions standards, the share of new car sales that are electric could fall to 32% in 2030.
But not all government support for electric vehicles will end by October 1, even if the bill gets the president’s signature in its current form.
“It’s important for consumers to know there are many states that offer subsidies, such as New York, and Colorado,” Cantor told me. That also goes for California, New Jersey, Nevada, and New Mexico. You can find the full list here.

Excise tax is out, foreign sourcing rules are in.
After more than three days of stops and starts on the Senate floor, Congress’ upper chamber finally passed its version of Trump’s One Big Beautiful Bill Act Tuesday morning, sending the tax package back to the House in hopes of delivering it to Trump by the July 4 holiday, as promised.
An amendment brought by Senators Joni Ernst and Chuck Grassley of Iowa and Lisa Murkowski of Alaska that would have more gradually phased down the tax credits for wind and solar rather than abruptly cutting them off was never brought to the floor. Instead, Murkowski struck a deal with the Senate leadership designed to secure her vote that accomplished some of her other priorities, including funding for rural hospitals, while also killing an excise tax on renewables that had only just been stuffed into the bill over the weekend.
The new tax on wind and solar would have driven up development costs by as much as 20% — a prospect that industry groups said would “kill” investment altogether. But even without the tax, the Senate’s bill would gum up the works for clean energy projects across the spectrum due to new phase-out schedules for tax credits and fast-approaching deadlines to meet complex foreign sourcing rules. While more projects will likely be built under this version than the previous one, the basic outcomes haven’t changed: higher energy costs, project delays, lost jobs, and ceding leadership in artificial intelligence and manufacturing to China.
"This bill will hit Americans hard, terminating credits that have helped families lower their energy and transportation costs, shrinking demand for American-made advanced energy technologies, and squeezing new domestic energy production at a time of rising demand and prices,” Heather O’Neill, the CEO and president of the trade group Advanced Energy United, said in a statement Tuesday. “The advanced energy industry will endure, but the downstream effects of these rollbacks and punitive policies will be felt by American families and businesses for years to come.”
Here’s what’s in the final Senate bill.
The final Senate bill bifurcates the previously technology-neutral tax credits for clean electricity into two categories with entirely different rules and timelines — wind and solar versus everything else.
Tax credits for wind and solar farms would end abruptly with no phase-out period, but the bill includes a significant safe harbor for projects that are already under construction or close to breaking ground. As long as a project starts construction within 12 months of the bill’s passage, it will be able to claim the tax credits as originally laid out in the Inflation Reduction Act. All other projects must be “placed in service,” i.e. begin operating, by the start of 2028 to qualify.
That means if Trump signs the bill into law on July 4, wind and solar developers will have until July 4 of 2026 to “start construction.” Otherwise, they will have less than a year and a half to bring their projects online and still qualify for the credits.
Meanwhile, all other sources of zero-emissions electricity, including batteries, advanced nuclear, geothermal, and hydropower, will be able to continue claiming the tax credits for nearly a decade. The credits would start phasing down for projects that start construction in 2034 and terminate in 2036.
While there are some potential wins in the bill for clean energy development, many of the safe harbored projects will still be subject to complex foreign sourcing rules that may prove too much of a burden to meet.
The bill requires that any zero-emissions electricity or advanced manufacturing project that starts construction after December of this year abide by strict new “foreign entities of concern,” or FEOC rules in order to be eligible for tax credits. The rules penalize companies for having financial or material connections to people or businesses that are “owned by, controlled by, or subject to the jurisdiction or direction of” any of four countries — Russia, Iran, North Korea, and most importantly for clean energy technology, China.
As with the text that came out of the Senate Finance committee, the text in the final bill would phase in supply chain restrictions, requiring project developers and manufacturers to use fewer and fewer Chinese-sourced inputs over time. For clean electricity projects starting construction next year, 40% of the value of the materials used in the project must be free of ties to a FEOC. By 2030, the threshold would rise to 60%. Energy storage facilities are subject to a more aggressive timeline and would be required to prove that 55% of the project materials are non-FEOC in 2026, rising to 75% by 2030. Each covered advanced manufacturing technology gets its own specific FEOC benchmarks.
Unlike the text from the Finance Committee, however, the final text includes a clear exception for developers who already have procurement contracts in place prior to the bill’s enactment. If a solar developer has already signed a contract to get its cells from a Chinese company, for example, it could exempt that cost from the calculation. That would make it easier for companies further along in the development process to comply with the eligibility rules.
That said, these materials sourcing rules come on top of strict ownership and licensing rules likely to block more than 100 existing and planned solar and battery factories with partial Chinese ownership or licensing deals with Chinese firms from receiving the tax credits, per a BloombergNEF analysis I reported on previously.
Once again, the details of how any of this will work — and whether it will, in fact, be “workable” — will depend heavily on guidance written by the Treasury department. That not only gives the Trump administration significant discretion over the rules, it also assumes that the Treasury department, which is now severely understaffed after Trump’s efficiency department cleaned house earlier this year, will actually have the bandwidth to write them. Without Treasury guidance, developers may not have the cost certainty they need to continue moving forward on projects.
Up until today, the Senate and House looked poised to destroy the business model for companies like Sunrun that lease rooftop solar installations to homeowners and businesses by cutting them off from the investment tax credit, which can bring down the cost of a solar array by as much as 70%. The final Senate bill, however, got rid of this provision and replaced it with a much more narrow version.
Now, the only “leasing” schemes that are barred from claiming tax credits are those for solar water heaters and small wind installations. Companies that lease solar panels, batteries, fuel cells, and geothermal heating equipment are still eligible. SunRun’s stock jumped nearly 10% on Tuesday.
Other than the new FEOC rules, which will have truly existential consequences for a great many projects, there aren’t many changes to the advanced manufacturing tax credit, or 45X, than in previous versions of the bill. The OBBBA would create a new phase-out schedule for critical mineral producers claiming the tax credit that begins in 2031. Previously, critical minerals were set to be eligible indefinitely. It would also terminate the credit for wind energy components early, in 2028.
One significant change from the Senate Finance text is that the bill would allow vertically integrated companies to stack the tax credit for multiple components.
But perhaps the biggest change, which was introduced last weekend, is a twisted new definition of “critical mineral” that allows metallurgical coal — the type of coal used in steelmaking — to qualify for the tax credit. As my colleague Matthew Zeitlin wrote, most of the metallurgical coal the U.S. produces is exported, meaning this subsidy will mostly help other countries produce cheaper steel.
It looks like the hydrogen industry’s intense lobbying efforts finally paid off: The final Senate bill is the first text we’ve seen since this process began in May that would extend the lifespan of the tax credit for clean hydrogen production. Now, projects that begin construction before January 1, 2028 will still qualify for the credit. This is shorter than the Inflation Reduction Act’s 2033 cut-off, but much longer than the end-of-year cliff earlier versions of the bill would have imposed.
The tax credits for electric vehicles and energy efficiency building improvements would end almost immediately. Consumers will have to purchase or lease a new or used EV before September 30, 2025, in order to benefit. There would be a slightly longer lead time to get an EV charger installed, but that credit (30C) would expire on June 30, 2026.
Meanwhile, energy efficiency upgrades such as installing a heat pump or better-insulated windows and doors would have to be completed by the end of this year in order to qualify. Same goes for self-financed rooftop solar. The tax credit for newly built energy efficiency homes would expire on June 30, 2026.
The bill would make similar changes to the carbon sequestration (45Q) and clean fuels (45Z) tax credits as previous versions, boosting the credit amount for carbon capture projects that do enhanced oil recovery, and extending the clean fuels credit to corn ethanol producers.
