That means, as the BloombergNEF policy associate Derrick Flakoll put it in an analysis published prior to the election, “the next administration and Congress will encounter a blank canvas of carbon capture infrastructure rules they can shape freely.”
Carbon capture is unique among climate technologies because it is, in most cases, a pure cost with no monetizable benefit. That means the policy environment — that great big blank canvas — is essential to determining which projects actually get built and whether the ones that do are actually useful for fighting climate change.
The next administration may or may not decide to take an interest in carbon capture, of course, but there’s reason to expect it will. Doug Burgum, Trump’s pick for the Department of the Interior who will also head up a new National Energy Council, has been a vocal supporter of carbon capture projects in his home state of North Dakota. Although Trump’s team will be looking for subsidies to cut in order to offset the tax breaks he has promised, his deep-pocketed supporters in the oil and gas industry who have made major investments in carbon capture based, in part, on the 45Q tax credit, will not want to see it on the chopping block. And carbon capture typically enjoys bipartisan support in Congress.
Congress first created the carbon capture tax credit in 2008, under the auspices of cleaning up the image of coal plants. Lawmakers updated the credit in 2018, and then again in 2022 with the Inflation Reduction Act, each iteration increasing the credit amount and expanding the types of projects that are eligible. Companies can now get up to $85 for every ton of CO2 captured from an industrial plant and sequestered underground, and $180 for every ton captured directly from the air. Combined with grants and loans in the 2021 Bipartisan Infrastructure Law, the changes have driven a surge in carbon capture and storage projects in the United States. More than 150 projects have been announced since the start of 2022, according to a database maintained by the International Energy Agency, compared to fewer than 100 over the four years prior.
Many of these projects are notably different from what has been proposed and tried in the past. Historically in the U.S., carbon capture has been used on coal-fired power plants, ethanol refineries, and at natural gas processing facilities, and almost all of the captured gas has been pumped into aging oil fields to help push more fuel out of the ground. But the new policy environment spurred at least some proposals in industries with few other options to decarbonize, including cement, hydrogen, and steel production. It also catalyzed projects that suck carbon directly from the air, versus capturing emissions at the source. Most developers now say they plan to sequester captured carbon underground rather than use it to drill for oil.
Only a handful of projects are actually under construction, however, and the prospects for others reaching that point are far from guaranteed. Inflation has eroded the value of the 45Q tax credit, Madelyn Morrison, the government affairs director for the Carbon Capture Coalition, told me. “Coupled with that, project deployment costs have really skyrocketed over the past several years. Some folks have said that equipment costs have gone up upwards of 50%,” she said.
Others aren’t sure whether they’ll even qualify, Flakoll told me. “There is a sort of shadow struggle going on over how permissive the credit is going to be in practice,” he said. For example, the IRA says that power plants have to capture 75% of their baseline emissions to be eligible, but it doesn’t specify how to calculate those baseline emissions. The Treasury solicited input on these questions and others shortly after the IRA passed. Comments raised concerns about how projects that share pipeline infrastructure should track and report their carbon sequestration claims. Environmental groups sought updates to the reporting and verification requirements to prevent taxpayer money from funding false or inflated claims. A 2020 investigation by the inspector general for tax administration found that during the first decade of the program, nearly $900 billion in tax credits were claimed for projects that did not comply with EPA reporting requirements. But the Treasury never followed up its request for comment with a proposed rule.
Permitting for carbon sequestration sites has also lagged. The Environmental Protection Agency has issued final permits for just one carbon sequestration project over the past four years, with a total of two wells. Fifty-five applications are currently under review.
Carbon dioxide pipeline projects have also faced opposition from local governments and landowners. In California, where lawmakers have generally supported the use of carbon capture for achieving state climate goals, and where more than a dozen projects have been announced, the legislature placed a moratorium on CO2 pipeline development until the federal government updates its safety regulations.
The incoming Congress and presidential administration could clear away some of these hurdles. Congress is already expected to get rid of or rewrite many of the IRA’s tax credit programs when it opens the tax code to address other provisions that expire next year. The Carbon Capture Coalition and other proponents are advocating for another increase to the value of the 45Q tax credit to adjust it for inflation. Trump’s Treasury department will have free rein to issue rules that make the credit as cheap and easy as possible to claim. The EPA, under new leadership, could also speed up carbon storage permitting or, perhaps more likely, grant primacy over permitting to the states.
But other Trump administration priorities could end up hurting carbon capture development. The projects with the surest path forward are the ones with the lowest cost of capture and multiple pathways for revenue generation, Rohan Dighe, a research analyst at Wood Mackenzie told me. For example, ethanol plants emit a relatively pure stream of CO2 that’s easy to capture, and doing so enables producers to access low-carbon fuel markets in California and Washington. Carbon capture at a steel plant or power plant is much more difficult, by contrast, as the flue gas contains a mix of pollutants.
On those facilities, the 45Q tax credit is too low to justify the cost, Dighe said, and other sources of revenue such as price premiums for green products are uncertain. “The Trump administration's been pretty clear in terms of wanting to deregulate, broadly speaking,” Dighe said, pointing to plans to axe the EPA’s power plant rules and the Securities and Exchange Commission’s climate disclosure requirements. “So those sorts of drivers for some of these projects moving forward are going to be removed.”
That means projects will depend more on voluntary corporate sustainability initiatives to justify investment. Does Amazon want to build a data center in West Texas? Is it willing to pay a premium for clean electricity from a natural gas plant that captures and stores its carbon?
But the regulatory environment still matters. Flakoll will be watching to see whether lax monitoring and reporting rules for carbon capture, if enacted, will hurt trust and acceptance of carbon capture projects to the point that companies find it difficult to find buyers for their products or insurance companies to underwrite them.
“There will be a more of a policy push for [CCS] to enter the market,” Flakoll said. “But it takes two to tango, and there's a question of how much the private sector will respond to that.”
