The good, the bad, and the hedge
America’s largest oil and gas company just secured the missing elements for it to become one of the nation’s most powerful players in the nascent carbon capture and storage industry.
ExxonMobil announced last week that it was purchasing Denbury Inc., giving it access to an extensive network of pipelines for transporting carbon dioxide and land holdings for injecting the pollutant underground. The nearly $5 billion all-stock sale is the biggest “carbon management” deal yet.
Carbon management is an emerging industry premised on constructing a labyrinth of factories and pipelines to capture emissions from the smokestacks of industrial facilities, and also directly from the atmosphere, and pump them into the Earth’s crust. Exxon has espoused its work on carbon capture for years, but the company’s investments have never matched its rhetoric, fueling accusations of greenwashing. Now, it suddenly seems to be positioning itself to become this carbon maze’s lead architect.
What does it all mean? The Biden administration and many clean energy researchers believe carbon capture may be the only way to reduce emissions from certain sectors like chemical manufacturing, steel making, and cement production — at least in the near term. Some argue that a company like Exxon has the expertise and capital to build this infrastructure, and that carbon management presents a new potential business model for the company. But the idea is controversial among many climate advocates who worry that it will serve solely to give Exxon and others license to continue digging up and selling fossil fuels.
Of course, it’s impossible to know Exxon’s intentions without being in the boardroom. But when I spoke to experts about what the acquisition of Danbury signaled, three theories emerged about the company’s motivations.
Exxon has claimed to be a leader in carbon capture for years, but until recently, the company’s only U.S. project consisted of a single site in Wyoming where Exxon processes natural gas. The carbon collected there was sold to other fossil fuel companies, including Denbury, to inject into depleted oil wells in order to squeeze more crude out of the ground — a technique known as enhanced oil recovery.
But the company has been under increased shareholder pressure over the last several years to do more to reduce its emissions and invest in clean industries. Exxon has long lagged its peers in even disclosing its carbon footprint, let alone setting targets to reduce it. But after activist investors won three seats on Exxon’s board in 2021, the company launched a Low Carbon Solutions business focused on carbon capture, clean hydrogen, and biofuels.
In just the past year, the new outfit has made deals with a handful of industrial emitters throughout the Gulf Coast to manage their carbon dioxide emissions. Exxon has announced contracts to haul off the carbon captured from an ammonia plant in Louisiana — the largest greenhouse gas emitter in the state — as well as a steel plant owned by Nucor and a yet-to-be-built hydrogen plant in Baytown, Texas. It also formed a partnership with Mitsubishi Heavy Industries, which has developed a leading solution for capturing carbon from industrial smokestacks.
The deal with Denbury will significantly speed up the company’s ability to deliver on those agreements. It gives Exxon access not only to 1,300 miles of carbon dioxide pipelines, but also to underground storage capacity estimated at 2 billion metric tons of CO2 — close to a third of what the U.S. emitted in 2021.
To Neil Quach, a former oil and gas analyst for Citigroup and UBS who now works at the think tank Carbon Tracker, the deal shows that Exxon is taking the low carbon future seriously — at least more seriously than its peers like Chevron. He recently authored a paper criticizing Exxon’s strategy, arguing that the company’s oil and gas portfolio was “highly vulnerable to the energy transition.”
“I’ve been arguing that they have to get into transition businesses in a more material way, and this is one step toward that,” he told me. At the same time, though, he noted that the $5 billion deal was still only a drop in the bucket — Exxon turned a $56 billion profit last year and is valued at $400 billion.
Though Exxon appears to be starting to build out a material carbon capture business, to some observers, the key question is, to what end?
“I’m not too enthralled with this purchase,” Dennis Wamsted, an energy analyst at the Institute for Energy Economics and Financial Analysis, and frequent critic of carbon capture, told me. “I see it as a way for Exxon to harvest subsidies from the U.S. government,” he said. “I don’t see this as a legitimate business effort by Exxon to lower its impact on the climate going forward.”
Wamsted was referring to tax credits for carbon capture that were recently juiced by the Inflation Reduction Act. Companies can now earn up to $85 for every metric ton of CO2 they collect from the smokestacks of factories and sequester — making it a potentially profitable endeavor for the first time.
There’s no question that Biden’s signature climate policy is a key motivator for Exxon and also Denbury. Previously, Denbury’s business model centered on using carbon dioxide for enhanced oil recovery. But the company has recently been scooping up acreage in Alabama, Louisiana, Mississippi, Texas, and Wyoming — 10 sites in all — for pure carbon sequestration.
This is what the tax credits were designed to do — otherwise, why would Exxon or Denbury bother spending money to bury carbon when it’s free to dump it into the atmosphere and profitable to use it to extract oil?
I asked Wamsted what would constitute a legitimate effort and whether it matters if Exxon is “harvesting subsidies” if the result is to lower emissions. But he’s not convinced the efforts will actually lead to climate-relevant results. Wamsted acknowledged that it’s challenging to cut emissions from certain industries like steelmaking in other ways, but he’s skeptical that carbon capture will ultimately be the best way to do it. In the case of Nucor, for example, Exxon’s project won’t fully eliminate the emissions produced by the steel plant.
“If there are things that work in five years I’ll give them credit for it,” Wamsted said, “but we have a very short timeframe here to try to get our carbon emissions under control.”
Many of Wamsted’s concerns, like of the safety and security of storing carbon underground, are shared by communities that live near Exxon’s potential injection sites, which could be a hurdle for the projects as they unfold. Many in the environmental justice movement fear that carbon capture will extend the life of polluting plants they would rather see shut down, and could even amplify the risks of living near these sites.
“In the real world, this is an experiment,” Beverly Wright, the executive director of the Deep South Center for Environmental Justice, told The Washington Post. “And this experiment is going to be conducted on the same communities that have suffered from the oil and gas industry.”
If there are two potential futures — one where the world allows the production of fossil fuels for decades to come, and one where production is forced to wind down — perhaps Exxon is just trying to prepare for both scenarios.
“When I looked at the Exxon investment in Denbury, I was curious if it actually signaled a change in how the company was thinking about the future,” Andrew Logan, the senior director of oil and gas at the sustainable investing nonprofit Ceres, told me. “Is it actually thinking the world is going to proceed toward decarbonization, and investing accordingly? Or is this just a way to cover the bases in case things don’t go as they expect?”
Since the Inflation Reduction Act completely changed the economics of carbon capture, Exxon doesn’t have to have had some big change of heart about the energy transition to see it as a good bet. And there’s no indication the company is slowing down its fossil fuel business. CEO Darren Woods announced in early June that he aimed to double the amount of oil Exxon fracks in the U.S. in the next five years. The acquisition of Denbury also comes with significant oil production capacity, including a new enhanced oil recovery project called the Cedar Creek Anticline expected to produce 12,500 barrels per day by late 2024. But in taking over Denbury’s pipelines, Exxon is also better positioned to grow its carbon capture business if it makes sense to.
One of the reasons deciphering all this is so hard is that for a long time the promise of carbon capture technology was used as a way to slow progress, and now it could actually bring about real world emission reductions. But that still depends on how it’s implemented, and whether or not it enables the continued use of fossil fuels.
“In a way, it makes it more complicated because you’re actually gonna see stuff built in a way that we haven’t for the last two decades,” said Logan. “But it still does not remove the need to take much more ambitious steps to bring down emissions elsewhere in the industry.”

And more on the week’s biggest conflicts around renewable energy projects.
1. Jackson County, Kansas – A judge has rejected a Hail Mary lawsuit to kill a single solar farm over it benefiting from the Inflation Reduction Act, siding with arguments from a somewhat unexpected source — the Trump administration’s Justice Department — which argued that projects qualifying for tax credits do not require federal environmental reviews.
2. Portage County, Wisconsin – The largest solar project in the Badger State is now one step closer to construction after settling with environmentalists concerned about impacts to the Greater Prairie Chicken, an imperiled bird species beloved in wildlife conservation circles.
3. Imperial County, California – The board of directors for the agriculture-saturated Imperial Irrigation District in southern California has approved a resolution opposing solar projects on farmland.
4. New England – Offshore wind opponents are starting to win big in state negotiations with developers, as officials once committed to the energy sources delay final decisions on maintaining contracts.
5. Barren County, Kentucky – Remember the National Park fighting the solar farm? We may see a resolution to that conflict later this month.
6. Washington County, Arkansas – It seems that RES’ efforts to build a wind farm here are leading the county to face calls for a blanket moratorium.
7. Westchester County, New York – Yet another resort town in New York may be saying “no” to battery storage over fire risks.
Solar and wind projects are getting swept up in the blowback to data center construction, presenting a risk to renewable energy companies who are hoping to ride the rise of AI in an otherwise difficult moment for the industry.
The American data center boom is going to demand an enormous amount of electricity and renewables developers believe much of it will come from solar and wind. But while these types of energy generation may be more easily constructed than, say, a fossil power plant, it doesn’t necessarily mean a connection to a data center will make a renewable project more popular. Not to mention data centers in rural areas face complaints that overlap with prominent arguments against solar and wind – like noise and impacts to water and farmland – which is leading to unfavorable outcomes for renewable energy developers more broadly when a community turns against a data center.
“This is something that we’re just starting to see,” said Matthew Eisenson, a senior fellow with the Renewable Energy Legal Defense Initiative at the Columbia University Sabin Center for Climate Change Law. “It’s one thing for environmentalists to support wind and solar projects if the idea is that those projects will eventually replace coal power plants. But it’s another thing if those projects are purely being built to meet incremental demand from data centers.”
We’ve started to see evidence of this backlash in certain resort towns fearful of a new tech industry presence and the conflicts over transmission lines in Maryland. But it is most prominent in Virginia, ground zero for American hyperscaler data centers. As we’ve previously discussed in The Fight, rural Virginia is increasingly one of the hardest places to get approval for a solar farm in the U.S., and while there are many reasons the industry is facing issues there, a significant one is the state’s data center boom.
I spent weeks digging into the example of Mecklenburg County, where the local Board of Supervisors in May indefinitely banned new solar projects and is rejecting those that were in the middle of permitting when the decision came down. It’s also the site of a growing data center footprint. Microsoft, which already had a base of operations in the county’s town of Boydton, is in the process of building a giant data center hub with three buildings and an enormous amount of energy demand. It’s this sudden buildup of tech industry infrastructure that is by all appearances driving a backlash to renewable energy in the county, a place that already had a pre-existing high opposition risk in the Heatmap Pro database.
It’s not just data centers causing the ban in Mecklenburg, but it’s worth paying attention to how the fight over Big Tech and solar has overlapped in the county, where Sierra Club’s Virginia Chapter has worked locally to fight data center growth with a grassroots citizens group, Friends of the Meherrin River, that was a key supporter of the solar moratorium, too.
In a conversation with me this week, Tim Cywinski, communications director for the state’s Sierra Club chapter, told me municipal leaders like those in Mecklenburg are starting to group together renewables and data centers because, simply put, rural communities enter into conversations with these outsider business segments with a heavy dose of skepticism. This distrust can then be compounded when errors are made, such as when one utility-scale solar farm – Geenex’s Grasshopper project – apparently polluted a nearby creek after soil erosion issues during construction, a problem project operator Dominion Energy later acknowledged and has continued to be a pain point for renewables developers in the county.
“I don’t think the planning that has been presented to rural America has been adequate enough,” the Richmond-based advocate said. “Has solar kind of messed up in a lot of areas in rural America? Yeah, and that’s given those communities an excuse to roll them in with a lot of other bad stuff.”
Cywinski – who describes himself as “not your typical environmentalist” – says the data center space has done a worse job at community engagement than renewables developers in Virginia, and that the opposition against data center projects in places like Chesapeake and Fauquier is more intense, widespread, and popular than the opposition to renewables he’s seeing play out across the Commonwealth.
But, he added, he doesn’t believe the fight against data centers is “mutually exclusive” from conflicts over solar. “I’m not going to tout the gospel of solar while I’m trying to fight a data center for these people because it’s about listening to them, hearing their concerns, and then not telling them what to say but trying to help them elevate their perspective and their concerns,” Cywinski said.
As someone who spends a lot of time speaking with communities resisting solar and trying to best understand their concerns, I agree with Cywinksi: the conflict over data centers speaks to the heart of the rural vs. renewables divide, and it offers a warning shot to anyone thinking AI will help make solar and wind more popular.
The One Big Beautiful Bill Act is one signature away from becoming law and drastically changing the economics of renewables development in the U.S. That doesn’t mean decarbonization is over, experts told Heatmap, but it certainly doesn’t help.
What do we do now?
That’s the question people across the climate change and clean energy communities are asking themselves now that Congress has passed the One Big Beautiful Bill Act, which would slash most of the tax credits and subsidies for clean energy established under the Inflation Reduction Act.
Preliminary data from Princeton University’s REPEAT Project (led by Heatmap contributor Jesse Jenkins) forecasts that said bill will have a dramatic effect on the deployment of clean energy in the U.S., including reducing new solar and wind capacity additions by almost over 40 gigawatts over the next five years, and by about 300 gigawatts over the next 10. That would be enough to power 150 of Meta’s largest planned data centers by 2035.
But clean energy development will hardly grind to a halt. While much of the bill’s implementation is in question, the bill as written allows for several more years of tax credit eligibility for wind and solar projects and another year to qualify for them by starting construction. Nuclear, geothermal, and batteries can claim tax credits into the 2030s.
Shares in NextEra, which has one of the largest clean energy development businesses, have risen slightly this year and are down just 6% since the 2024 election. Shares in First Solar, the American solar manufacturer, are up substantially Thursday from a day prior and are about flat for the year, which may be a sign of investors’ belief that buyer demand for solar panels will persist — or optimism that the OBBBA’s punishing foreign entity of concern requirements will drive developers into the company’s arms.
Partisan reversals are hardly new to climate policy. The first Trump administration gleefully pulled the rug from under the Obama administration’s power plant emissions rules, and the second has been thorough so far in its assault on Biden’s attempt to replace them, along with tailpipe emissions standards and mileage standards for vehicles, and of course, the IRA.
Even so, there are ways the U.S. can reduce the volatility for businesses that are caught in the undertow. “Over the past 10 to 20 years, climate advocates have focused very heavily on D.C. as the driver of climate action and, to a lesser extent, California as a back-stop,” Hannah Safford, who was director for transportation and resilience in the Biden White House and is now associate director of climate and environment at the Federation of American Scientists, told Heatmap. “Pursuing a top down approach — some of that has worked, a lot of it hasn’t.”
In today’s environment, especially, where recognition of the need for action on climate change is so politically one-sided, it “makes sense for subnational, non-regulatory forces and market forces to drive progress,” Safford said. As an example, she pointed to the fall in emissions from the power sector since the late 2000s, despite no power plant emissions rule ever actually being in force.
“That tells you something about the capacity to deliver progress on outcomes you want,” she said.
Still, industry groups worry that after the wild swing between the 2022 IRA and the 2025 OBBBA, the U.S. has done permanent damage to its reputation as a business-friendly environment. Since continued swings at the federal level may be inevitable, building back that trust and creating certainty is “about finding ballasts,” Harry Godfrey, the managing director for Advanced Energy United’s federal priorities team, told Heatmap.
The first ballast groups like AEU will be looking to shore up is state policy. “States have to step up and take a leadership role,” he said, particularly in the areas that were gutted by Trump’s tax bill — residential energy efficiency and electrification, transportation and electric vehicles, and transmission.
State support could come in the form of tax credits, but that’s not the only tool that would create more certainty for businesses — considering the budget cuts states will face as a result of Trump’s tax bill, it also might not be an option. But a lot can be accomplished through legislative action, executive action, regulatory reform, and utility ratemaking, Godfrey said. He cited new virtual power plant pilot programs in Virginia and Colorado, which will require further regulatory work to “to get that market right.”
A lot of work can be done within states, as well, to make their deployment of clean energy more efficient and faster. Tyler Norris, a fellow at Duke University's Nicholas School of the Environment, pointed to Texas’ “connect and manage” model for connecting renewables to the grid, which allows projects to come online much more quickly than in the rest of the country. That’s because the state’s electricity market, ERCOT, does a much more limited study of what grid upgrades are needed to connect a project to the grid, and is generally more tolerant of curtailing generation (i.e. not letting power get to the grid at certain times) than other markets.
“As Texas continues to outpace other markets in generator and load interconnections, even in the absence of renewable tax credits, it seems increasingly plausible that developers and policymakers may conclude that deeper reform is needed to the non-ERCOT electricity markets,” Norris told Heatmap in an email.
At the federal level, there’s still a chance for, yes, bipartisan permitting reform, which could accelerate the buildout of all kinds of energy projects by shortening their development timelines and helping bring down costs, Xan Fishman, senior managing director of the energy program at the Bipartisan Policy Center, told Heatmap. “Whether you care about energy and costs and affordability and reliability or you care about emissions, the next priority should be permitting reform,” he said.
And Godfrey hasn’t given up on tax credits as a viable tool at the federal level, either. “If you told me in mid-November what this bill would look like today, while I’d still be like, Ugh, that hurts, and that hurts, and that hurts, I would say I would have expected more rollbacks. I would have expected deeper cuts,” he told Heatmap. Ultimately, many of the Inflation Reduction Act’s tax credits will stick around in some form, although we’ve yet to see how hard the new foreign sourcing requirements will hit prospective projects.
While many observers ruefully predicted that the letter-writing moderate Republicans in the House and Senate would fold and support whatever their respective majorities came up with — which they did, with the sole exception of Pennsylvania Republican Brian Fitzpatrick — the bill also evolved over time with input from those in the GOP who are not openly hostile to the clean energy industry.
“You are already seeing people take real risk on the Republican side pushing for clean energy,” Safford said, pointing to Alaska Republican Senator Lisa Murkowski, who opposed the new excise tax on wind and solar added to the Senate bill, which earned her vote after it was removed.
Some damage has already been done, however. Canceled clean energy investments adds up to $23 billion so far this year, compared to just $3 billion in all of 2024, according to the decarbonization think tank RMI. And that’s before OBBBA hits Trump’s desk.
The start-and-stop nature of the Inflation Reduction Act may lead some companies, states, local government and nonprofits to become leery of engaging with a big federal government climate policy again.
“People are going to be nervous about it for sure,” Safford said. “The climate policy of the future has to be polycentric. Even if you have the political opportunity to make a big swing again, people will be pretty gun shy. You will need to pursue a polycentric approach.”
But to Godfrey, all the back and forth over the tax credits, plus the fact that Republicans stood up to defend them in the 11th hour, indicates that there is a broader bipartisan consensus emerging around using them as a tool for certain energy and domestic manufacturing goals. A future administration should think about refinements that will create more enduring policy but not set out in a totally new direction, he said.
Albert Gore, the executive director of the Zero Emissions Transportation Association, was similarly optimistic that tax credits or similar incentives could work again in the future — especially as more people gain experience with electric vehicles, batteries, and other advanced clean energy technologies in their daily lives. “The question is, how do you generate sufficient political will to implement that and defend it?” he told Heatmap. “And that depends on how big of an economic impact does it have, and what does it mean to the American people?”
Ultimately, Fishman said, the subsidy on-off switch is the risk that comes with doing major policy on a strictly partisan basis.
“There was a lot of value in these 10-year timelines [for tax credits in the IRA] in terms of business certainty, instead of one- or two- year extensions,” Fishman told Heatmap. “The downside that came with that is that it became affiliated with one party. It was seen as a partisan effort, and it took something that was bipartisan and put a partisan sheen on it.”
The fight for tax credits may also not be over yet. Before passage of the IRA, tax credits for wind and solar were often extended in a herky-jerky bipartisan fashion, where Democrats who supported clean energy in general and Republicans who supported it in their districts could team up to extend them.
“You can see a world where we have more action on clean energy tax credits to enhance, extend and expand them in a future congress,” Fishman told Heatmap. “The starting point for Republican leadership, it seemed, was completely eliminating the tax credits in this bill. That’s not what they ended up doing.”
