Low-cost CO2 sorbents
Solid or liquid materials that capture CO2 from ambient air with high capacity, fast kinetics and low regeneration energy, for years of cycles, at a material cost low enough for gigatonne removal.
Scope
In: amines on supports, metal-organic frameworks, hydroxide and carbonate loops for direct air capture. Out: sorbents for flue gas at 4 to 15% CO2 and membranes (materials/high-selectivity-membranes).
