The Environmental Protection Agency is working on a new rule that would set stringent limits on carbon dioxide (CO₂) emissions from US power plants. Utilities would be required to retrofit existing plants with carbon capture and storage (CCS) technology or to switch to hydrogen fuel. Others call for the use of CCS to decarbonize heavy industry. But the cost of capture and the amount of CO₂ that proponents say needs to be captured crush any ideas about feasibility.

Carbon capture and storage is the process of capturing carbon dioxide from an industrial plant before it enters the atmosphere, transporting it, and storing it for centuries to millennia. Capture may be accomplished by filtering it from combustion exhaust streams. Pipelines are proposed to transport the captured CO₂. Underground reservoirs could be used for storage. For the last two decades, advocates have proposed…
