University of Helsinki Develops Superbase Technology to Reduce CO2 Capture Costs by 50%
Researchers at the University of Helsinki have introduced a novel direct air capture technology that utilizes a superbase-alcohol filtration fluid, achieving CO2 absorption of 156 mg per gram. This method allows CO2 release at 70 degrees Celsius, significantly lowering energy requirements compared to traditional amine-based systems that require over 100 degrees Celsius.
Early tests indicate the superbase is reusable with over 90% capacity retained after 20 cycles, enhancing its commercial viability. The technology could reduce operational costs of carbon capture by 50%, making it a potential game-changer in achieving gigaton-scale carbon removal needed for climate goals.
Plans for field trials in 2026 are underway, with partnerships aimed at validating the technology in real-world conditions. Finland is increasing support for carbon removal initiatives, positioning the Helsinki team as leaders in sustainable chemistry.
