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.”

New York City may very well be the epicenter of this particular fight.
It’s official: the Moss Landing battery fire has galvanized a gigantic pipeline of opposition to energy storage systems across the country.
As I’ve chronicled extensively throughout this year, Moss Landing was a technological outlier that used outdated battery technology. But the January incident played into existing fears and anxieties across the U.S. about the dangers of large battery fires generally, latent from years of e-scooters and cellphones ablaze from faulty lithium-ion tech. Concerned residents fighting projects in their backyards have successfully seized upon the fact that there’s no known way to quickly extinguish big fires at energy storage sites, and are winning particularly in wildfire-prone areas.
How successful was Moss Landing at enlivening opponents of energy storage? Since the California disaster six months ago, more than 6 gigawatts of BESS has received opposition from activists explicitly tying their campaigns to the incident, Heatmap Pro® researcher Charlie Clynes told me in an interview earlier this month.
Matt Eisenson of Columbia University’s Sabin Center for Climate Law agreed that there’s been a spike in opposition, telling me that we are currently seeing “more instances of opposition to battery storage than we have in past years.” And while Eisenson said he couldn’t speak to the impacts of the fire specifically on that rise, he acknowledged that the disaster set “a harmful precedent” at the same time “battery storage is becoming much more present.”
“The type of fire that occurred there is unlikely to occur with modern technology, but the Moss Landing example [now] tends to come up across the country,” Eisenson said.
Some of the fresh opposition is in rural agricultural communities such as Grundy County, Illinois, which just banned energy storage systems indefinitely “until the science is settled.” But the most crucial place to watch seems to be New York City, for two reasons: One, it’s where a lot of energy storage is being developed all at once; and two, it has a hyper-saturated media market where criticism can receive more national media attention than it would in other parts of the country.
Someone who’s felt this pressure firsthand is Nick Lombardi, senior vice president of project development for battery storage company NineDot Energy. NineDot and other battery storage developers had spent years laying the groundwork in New York City to build out the energy storage necessary for the city to meet its net-zero climate goals. More recently they’ve faced crowds of protestors against a battery storage facility in Queens, and in Staten Island endured hecklers at public meetings.
“We’ve been developing projects in New York City for a few years now, and for a long time we didn’t run into opposition to our projects or really any sort of meaningful negative coverage in the press. All of that really changed about six months ago,” Lombardi said.
The battery storage developer insists that opposition to the technology is not popular and represents a fringe group. Lombardi told me that the company has more than 50 battery storage sites in development across New York City, and only faced “durable opposition” at “three or four sites.” The company also told me it has yet to receive the kind of email complaint flood that would demonstrate widespread opposition.
This is visible in the politicians who’ve picked up the anti-BESS mantle: GOP mayoral candidate Curtis Sliwa’s become a champion for the cause, but mayor Eric Adams’ “City of Yes” campaign itself would provide for the construction of these facilities. (While Democratic mayoral nominee Zohran Mamdani has not focused on BESS, it’s quite unlikely the climate hawkish democratic socialist would try to derail these projects.)
Lombardi told me he now views Moss Landing as a “catalyst” for opposition in the NYC metro area. “Suddenly there’s national headlines about what’s happening,” he told me. “There were incidents in the past that were in the news, but Moss Landing was headline news for a while, and that combined with the fact people knew it was happening in their city combined to create a new level of awareness.”
He added that six months after the blaze, it feels like developers in the city have a better handle on the situation. “We’ve spent a lot of time in reaction to that to make sure we’re organized and making sure we’re in contact with elected officials, community officials, [and] coordinated with utilities,” Lombardi said.
And more on the biggest conflicts around renewable energy projects in Kentucky, Ohio, and Maryland.
1. St. Croix County, Wisconsin - Solar opponents in this county see themselves as the front line in the fight over Trump’s “Big Beautiful” law and its repeal of Inflation Reduction Act tax credits.
2. Barren County, Kentucky - How much wood could a Wood Duck solar farm chuck if it didn’t get approved in the first place? We may be about to find out.
3. Iberia Parish, Louisiana - Another potential proxy battle over IRA tax credits is going down in Louisiana, where residents are calling to extend a solar moratorium that is about to expire so projects can’t start construction.
4. Baltimore County, Maryland – The fight over a transmission line in Maryland could have lasting impacts for renewable energy across the country.
5. Worcester County, Maryland – Elsewhere in Maryland, the MarWin offshore wind project appears to have landed in the crosshairs of Trump’s Environmental Protection Agency.
6. Clark County, Ohio - Consider me wishing Invenergy good luck getting a new solar farm permitted in Ohio.
7. Searcy County, Arkansas - An anti-wind state legislator has gone and posted a slide deck that RWE provided to county officials, ginning up fresh uproar against potential wind development.
Talking local development moratoria with Heatmap’s own Charlie Clynes.
This week’s conversation is special: I chatted with Charlie Clynes, Heatmap Pro®’s very own in-house researcher. Charlie just released a herculean project tracking all of the nation’s county-level moratoria and restrictive ordinances attacking renewable energy. The conclusion? Essentially a fifth of the country is now either closed off to solar and wind entirely or much harder to build. I decided to chat with him about the work so you could hear about why it’s an important report you should most definitely read.
The following chat was lightly edited for clarity. Let’s dive in.
Tell me about the project you embarked on here.
Heatmap’s research team set out last June to call every county in the United States that had zoning authority, and we asked them if they’ve passed ordinances to restrict renewable energy, or if they have renewable energy projects in their communities that have been opposed. There’s specific criteria we’ve used to determine if an ordinance is restrictive, but by and large, it’s pretty easy to tell once a county sends you an ordinance if it is going to restrict development or not.
The vast majority of counties responded, and this has been a process that’s allowed us to gather an extraordinary amount of data about whether counties have been restricting wind, solar and other renewables. The topline conclusion is that restrictions are much worse than previously accounted for. I mean, 605 counties now have some type of restriction on renewable energy — setbacks that make it really hard to build wind or solar, moratoriums that outright ban wind and solar. Then there’s 182 municipality laws where counties don’t have zoning jurisdiction.
We’re seeing this pretty much everywhere throughout the country. No place is safe except for states who put in laws preventing jurisdictions from passing restrictions — and even then, renewable energy companies are facing uphill battles in getting to a point in the process where the state will step in and overrule a county restriction. It’s bad.
Getting into the nitty-gritty, what has changed in the past few years? We’ve known these numbers were increasing, but what do you think accounts for the status we’re in now?
One is we’re seeing a high number of renewables coming into communities. But I think attitudes started changing too, especially in places that have been fairly saturated with renewable energy like Virginia, where solar’s been a presence for more than a decade now. There have been enough projects where people have bad experiences that color their opinion of the industry as a whole.
There’s also a few narratives that have taken shape. One is this idea solar is eating up prime farmland, or that it’ll erode the rural character of that area. Another big one is the environment, especially with wind on bird deaths, even though the number of birds killed by wind sounds big until you compare it to other sources.
There are so many developers and so many projects in so many places of the world that there are examples where either something goes wrong with a project or a developer doesn’t follow best practices. I think those have a lot more staying power in the public perception of renewable energy than the many successful projects that go without a hiccup and don’t bother people.
Are people saying no outright to renewable energy? Or is this saying yes with some form of reasonable restrictions?
It depends on where you look and how much solar there is in a community.
One thing I’ve seen in Virginia, for example, is counties setting caps on the total acreage solar can occupy, and those will be only 20 acres above the solar already built, so it’s effectively blocking solar. In places that are more sparsely populated, you tend to see restrictive setbacks that have the effect of outright banning wind — mile-long setbacks are often insurmountable for developers. Or there’ll be regulations to constrict the scale of a project quite a bit but don’t ban the technologies outright.
What in your research gives you hope?
States that have administrations determined to build out renewables have started to override these local restrictions: Michigan, Illinois, Washington, California, a few others. This is almost certainly going to have an impact.
I think the other thing is there are places in red states that have had very good experiences with renewable energy by and large. Texas, despite having the most wind generation in the nation, has not seen nearly as much opposition to wind, solar, and battery storage. It’s owing to the fact people in Texas generally are inclined to support energy projects in general and have seen wind and solar bring money into these small communities that otherwise wouldn’t get a lot of attention.
