The proposed Carbon Capture Modernization Act (2019) would correct design flaws in the 26 USC §48A CCS tax incentive program that have made it impossible for companies to access existing incentives to retrofit currently operating coal-fired power plants with carbon capture technology. Fixes in the legislation include removing efficiency requirements that are incompatible with carbon capture (while still achieving far greater emission reductions than from efficiency improvements alone), lowering the percentage CO2 capture requirement for existing units to improve project economics, lowering the size threshold for eligible projects and directing the Treasury Department to offer additional application rounds to reallocate available 48A credits.
