About
CO2CirculAir is a Dutch DAC start-up based in Arnhem developing SMART-DAC, a passive wind-driven direct air capture system using membrane gas absorption with a KOH-based solvent and membrane electrolysis/electrodialysis for regeneration. The company led a UK-based pilot under the DESNZ Greenhouse Gas Removal Innovation Programme (Phase 1 and Phase 2), with first CO2 captured in September 2023 and pilot operation reported through April 2025.
