The captured carbon dioxide will then be piped down into saline aquifers more than a mile underground, where it should be sequestered permanently. Big Tech is suddenly betting big on this form of carbon removal, known as bioenergy with carbon capture and storage, or BECCS. The sector also includes biomass-fueled power plants, waste incinerators, and biofuel refineries that add carbon capturing equipment to their facilities. BECCS now accounts for nearly 70% of the announced contracts in carbon removal, a popularity due largely to the fact that it can be tacked onto industrial facilities already operating on large scales. That undermines the logic of dedicating more of the world’s limited land, crops, and woods to such projects, he argues.
