Susteon Inc. is teaming with Columbia University, Applied Catalysts, and Kiewit Engineering to advance the development of a “reactive” direct air capture (DAC) process that is capable of capturing and converting carbon dioxide (CO2) from air into valuable products. The reactive DAC process involves selective chemisorption of CO2, followed by sorbent regeneration through reversible desorption or, optionally, catalytic conversion of adsorbed CO2 into methane (CH4; also referred to as renewable natural gas [RNG]), using waste or renewable hydrogen (H2).
