Overview
Even as nations diversify their energy portfolios, fossil fuels are expected to meet a majority of the world’s energy demand for several decades. Accelerating deployment of carbon capture technology is essential to reduce emissions from these power plants, and from industrial plants like cement and steel manufacturing.
More than half of the models cited in the Intergovernmental Panel on Climate Change’s Fifth Assessment Report required carbon capture for a goal of staying within 2 degrees Celsius of warming from pre-industrial days. For models without carbon capture, emissions reduction costs rose 138 percent.
For nearly a half century, in a practice called enhanced oil recovery (EOR), carbon dioxide has been used to extract additional oil from developed oil fields in the United States. U.S. companies are also investing in new technologies to re-use captured carbon emissions in innovative ways, including jet fuel and automobile seats. Spurred by the NRG COSIA Carbon XPRIZE, researchers are exploring even more uses, such as transforming carbon emissions into algae biofuels and building materials.
As many experts see hydrogen as a clean fuel of the future and expect it to play a major role in decarbonizing the industrial sector, a process such as natural gas reforming with carbon capture technology presents itself as the lowest cost option for producing clean hydrogen. This process produces “blue hydrogen” by reforming natural gas into hydrogen and carbon dioxide; the carbon dioxide by-product will be captured, transported, and stored in deep geologic formations. The addition of carbon capture makes the hydrogen production process nearly emissions free, when clean electricity is used to power the carbon capture facility.
Policy Support for Carbon Capture
There is strong bipartisan support to accelerate carbon capture deployment. In February 2018, Congress extended and expanded key financial incentives for investment in several advanced low-carbon technologies. The two-year budget package included the FUTURE Act, sponsored by Senators Heidi Heitkamp (D-N.D.), Shelley Moore Capito (R-W.Va.), Sheldon Whitehouse (D-R.I.), and John Barrasso (R-Wyo.). The legislation reforms and extends a federal tax credit to boost carbon capture, known asSection 45Q. The FUTURE Act also allows for the first time use of the tax credit for capture of carbon monoxide from industrial facilities like steel mills, direct air capture (DAC) of carbon dioxidefrom the atmosphere, and for the conversion of captured carbon into useful products.
In 2018, the California’s Low Carbon Fuel Standard (LCFS) was amended to enable carbon capture and storage projects that are associated with the production of transport fuels sold in California to generate LCFS credits. It also enabled DAC projects to generate credits regardless of their location even if they do not have a fuel component as the only exception to the rule. These changes came into effect in January 2019.
In December 2020, Congress enacted a two-year extension of the 45Q tax credit as a part of theConsolidated Appropriations Act, 2021to require qualified facilities to commence construction by December 31, 2025.
C2ES and the Great Plains Institute co-convene a diverse coalition of industry, labor, and environmental groups that support expanding deployment of carbon capture. Other supporters of incentivizing carbon capture include the Western Governors Association, Southern States Energy Board, and National Association of Regulatory Utility Commissioner
Carbon Capture in Action
As of 2020, at least 26 commercial-scale carbon capture projects are operating around the world with 21 more in early development and 13 in advanced development reaching front end engineering design (FEED). Industrial processes where large-scale carbon capture has been demonstrated and is in commercial operation include coal gasification, ethanol production, fertilizer production, natural gas processing, refinery hydrogen production and, most recently, coal-fired power generation.
Carbon Capture Milestones

1982: Koch Nitrogen Company Enid Fertilizer plant in Oklahoma. This fertilizer production plant supplies carbon dioxide to oil fields in southern Oklahoma.
1986:Exxon Shute Creek Gas Processing Facility in Wyoming. This natural gas processing plant serves ExxonMobil, Chevron, and Anadarko Petroleum carbon dioxide pipeline systems to oil fields in Wyoming and Colorado and is the largest commercial carbon capture facility in the world at 7 million tons of capacity annually.
1996: Sleipner Carbon Dioxide Storage Facility offshore of Norway. This project captures carbon dioxide from gas development for storage in an offshore sandstone reservoir. It was the world’s first geologic storage project. Roughly 0.85 million tonnes of CO2 is injected annually for a cumulative total of over 16.5 million tonnes as of January 2017.
2000: Dakota Gasification’s Great Plains Synfuels Plant in North Dakota. This coal gasification plant produces synthetic natural gas, fertilizer, and other byproducts.
