US seeks to allow carbon storage on federal land

President Joe Biden's administration is advancing a proposal to allow carbon capture and storage (CCS) on millions of acres of federal land owned by the US Forest Service.

The proposed rule, published Friday, would open up the possibility of siting carbon storage projects on the 193mn acres of federal land in 44 states managed by the Forest Service. The regulation could support the Biden administration's push to expand the use of CCS, a technology that captures CO2 and then stores it deep underground in subsurface geological formations.

The proposal would remove an existing restriction from the Forest Service that blocks projects from having "exclusive and perpetual use" of federal land. Because CCS projects store CO2 for thousands of years, the agency said the restriction needs to be removed for projects to advance. Projects would still be subject to other permitting requirements and environmental reviews.

The US has seen a surge of interest in CCS as developers try to take advantage of $12bn in new funding from the 2021 infrastructure law and the expansion of the "45Q" tax credit that pays up to $85/metric tonne of CO2 that is stored in geologic formations. The Inflation Reduction Act also offers tax credits for clean hydrogen and low-carbon renewables fuels that are likely to rely partially on CCS.

But project developers have run into obstacles as they seek regulatory approvals for CO2 pipelines and Class VI injection wells needed for CCS. US Senate Energy and Natural Resources Committee chairman Joe Manchin (D-West Virginia) on Thursday criticized the US Environmental Protection Agency for not yet approving permits for a backlog of 169 carbon injection wells, while at the same time proposing to mandate CCS for fossil fuel power plants.

"Not a single Class VI well has been approved," Manchin said. "At the same time, the administration is more than happy to mandate widespread deployment of carbon capture on gas- and coal-fired power plants."
