The Direct air capture team is responsible for obtaining sufficient quantities of CO2 for the process. The current process is vacuum – temperature swing adsorption and consists of three phases:
- Adsorption phase: air is continuously fanned through a chamber, CO2 and H2O are adsorbed.
- Vacuum creation phase: inthis phase, the chamber is pumped toward vacuum.
- Desorption phase: at elevated temperatures, and lower (partial) pressures, the CO2 & H2O desorb
