Carbon sequestration wells will swell from a few to more than 40

For all the talk of carbon dioxide sequestration, not many sites today are injecting CO 2 underground for permanent storage. That’s likely to change in 2024 as the US Environmental Protection Agency and other government bodies around the world approve a raft of permits for project developers eager to start storing CO 2 . The EPA regulates CO 2 sequestration as part of its authority over underground waste disposal under the Safe Drinking Water Act of 1974. The approval needed to store the greenhouse gas is called a Class VI well permit. Classes I-V are for other types of gas and liquid waste. The agriculture giant ADM has two Class VI permits, the only ones issued by the EPA as of Jan. 1 2 . Both are for its complex in Decatur, Illinois, where it injects CO 2 generated during ethanol production. The first was a demonstration project that buried © 2024 Chemical & Engineering News.
