Global Thermostat has one of a half dozen new processes for carbon capture that are in the field pilot stage. Global Thermostat has some star power execs and a Bronfman billionaire as a backer so hopefully can scale up to an industrial operation.
The carbon capture industry has been dominated by amine based processes that have been around since the 1950's and have reached their technical limits. The amine solvent process requires massive amounts of heat and is expensive. That didn't stop the Canadian and Alberta governments from dumping about a billion dollars of public money into two industrial scale amine CO2 capture projects at the Boundary coal plant in Saskatchewan (SaskPower) and into Shell's Quest project in Alberta ( though Shell invested only a small fraction of the project cost). Both have high operating costs and have never performed to projections. There are similar amine based CO2 capture follies around the world.
Meanwhile the promising low cost non amine carbon capture world is still in infancy and most startups struggle to get enough capital to keep going. Quebec based CO2 Solutions which had a low cost process, proven at field pilot stage, is now in receivership. Hopefully Global Thermostat, Inventys, Carbon Engineering and some of the others can avoid that fate and scale up.
