Global Thermostat’s own promotional materials mention two applications: using gaseous CO2 to carbonate soft drinks, and using the captured carbon to make baking soda for cattle feed and hydrochloric acid, which is also used in the food sector. Skyonic is currently using GT’s technology to do the latter. In addition, liquid CO2 is used widely in the food industry for refrigeration and preservation of meats and frozen foods. Gaseous CO2 is used to improve the shelf life of certain kinds of packaged foods, in a mixture of gases called MAP (Modified Atmosphere Packaging), which has very little oxygen. CO2 is also be used to remove the caffeine from coffee beans to make them decaf. The food industry is a large industry for CO2; according to gasworld.com, in developed economies, 30-40% of commercial CO2 use is for food production.
