About this opportunity
Every direct air capture (DAC) system depends on its sorbent, and every sorbent eventually wears out. This DAC from Los Alamos National Laboratory tackles that weakness head-on. It replaces the harsh release step with a gentler, ammonia-assisted process, which shields amine-based sorbents from the degradation that drives up operating costs. The method works with a broad family of established sorbent materials and support structures, so developers can build it into existing capture designs rather than starting over. Challenges Direct air capture is a two-step cycle: a sorbent captures CO2 from the air, then releases it as a concentrated stream. Liquid sorbents need expensive equipment and a lot of energy, more than 400 kJ of work per mole of CO2. Amine-based solid sorbents capture more CO2,...
