After 20 years of planning and conjecture, by the end of 2020 carbon capture and storage (CCS) facilities stored just 0.1% of global CO2 emissions. . . . The highest ratio in the history of science: the number of academic papers written on CCS divided by real-life implementation of it. . . . The Princeton CCS buildout, just to sequester an amount equal to 15% of current US GHG emissions, would require infrastructure whose throughput volume would be higher than the volume of oil flowing through US distribution and refining pipelines, a system which has taken over 100 years to build. . . . Sequestering 25% of global CO2 through direct air capture would require 25%-40% of the world’s electricity generation plus 11%-17% of its primary energy.
