- A new method to capture CO2 from the air developed at the University of Helsinki.
- CO2 can be released at 70°C in 30 minutes, making it reusable.
- Current methods require temperatures above 900°C for CO2 release.
- The compound retains 75% capacity after 50 cycles and 50% after 100 cycles.
- The key base used is 1,5,7-triazabicyclo [4.3.0] non-6-ene (TBN).
- The compound is non-toxic and cost-effective.
- Pilot testing at near-industrial scale is the next step.
- The compound may be bound to silica or graphene oxide for better CO2 interaction.
