But all of them are trying to bring down the high energy needs, and hence cost, of DAC.
The key divide is between high-temperature and low-temperature DAC. Two of the three most established DAC companies, Swiss-based Climeworks and Global Thermostat, based in Colorado, use low-temperature technologies, with sorbents that attract CO2 molecules to stick to the sorbent surface.
