This 13-page note aims to quantify the upside case for CCS in the United States, using economics, top-down and bottom-up calculations. Our conclusion is that a clear, $100/ton incentive could help CCS scale by c25x, accelerating over 500MTpa of projects in the next decade, which could prevent almost 10% of the USโs current CO2 emissions. Our numbers include blue hydrogen and next-gen CCS.
