Global Thermostat LLC (GT) (www.global thermostat.com) was formed in 2006 to develop and commercialize a unique technology for the direct capture of carbon dioxide from the atmosphere and other sources. The GT process “co-generates” carbon capture with other industrial processes—such as power production—by using the process heat from those processes to drive its carbon capture technology.
By combining CO2 capture from air along with capture from the flue gas of an electrical power plant, and using the power plant’s low cost process heat to provide the energy needed for the air capture process, GT technology has the capability of transforming power plants into net carbon sinks. Global Thermostat technology also can work with renewable power plants, because it captures carbon directly from air using the plant’s process heat. For example, heat from a Concentrated Solar Plant (CSP) can be used by Global Thermostat to drive its capture process.
CO2 capture from air is different from other forms of carbon capture in that it extracts CO2 directly from the atmosphere at low temperatures and at a concentration of about 400 parts per million (ppm). Other carbon capture technologies typically extract CO2 only from flue gases at higher temperatures and ppm. Global Thermostat technology also can work very economically in conjunction with standard capture technology by combining air and the flue as its sources of carbon.
