Finnish researchers hail new CO2 air capture using compounds
A new method to capture carbon dioxide from the air has been developed at the University of Helsinki’s chemistry department.
The method is based on a compound of superbase and alcohol.
Tests from professor Timo Repo’s group show that the compound appears promising: one gramme of the compound can absorb 156 milligrammes of CO2 directly from untreated ambient air.
However, the compound does not react with nitrogen, oxygen or other atmospheric gases.
The CO2 captured by the compound can be released by heating the compound at 70°C in 30 minutes. Clean CO2 is recovered and can be recycled.
