Researchers at the University of Helsinki described a new liquid absorbent for direct air capture in Environmental Science & Technology. The formulation combines a carbon-catching superbase with an alcohol, enabling selective uptake of carbon dioxide while ignoring other atmospheric gases. Tests showed one gram absorbed 156 milligrams of CO2, then released it when heated to about 158°F, far below typical regeneration temperatures. The material remained reusable across dozens of capture–release cycles, and the team plans near-industrial trials.
Why it matters
Lower-temperature regeneration could reduce energy costs for direct air capture, improving the economics and scalability of carbon removal systems.
