Direct capture of CO 2 from ambient air is technically feasible today, with commercial units already in operation. A demonstrated technology for achieving direct air capture (DAC) is chemical separation of CO 2 in a steam-assisted temperature-vacuum swing adsorption (S-TVSA) process. However, the po...
