Electrified release of pure CO2 from postcapture liquid: A two-stage system lowers the total energy cost

Proceedings of the National Academy of Sciences, Volume 123, Number 9, March 2026.
ImportanceElectrochemical methods that directly release CO2 from liquids captured directly from the air offer a promising route to low-carbon industrial cycles, but are often hampered by high energy demand and complex gas separation. We report a two-step phenomenon…
