Carbon dioxide elongatus" has been genetically engineered to produce the fuels isobutyraldehyde and isobutanol from using photosynthesis. Liquid and solid carbon dioxide are important refrigerants, especially in the food industry, where they are employed during the transportation and storage of ice cream and other frozen foods. Solid carbon dioxide is called "dry ice" and is used for small shipments where refrigeration equipment is not practical. Solid carbon dioxide is always below −78.5 °C at regular atmospheric pressure, regardless of the air temperature. The global automobile industry is expected to decide on the next-generation refrigerant in car air conditioning. is one discussed option.(see
Carbon dioxide cleaning In addition, care must be taken to prevent the concentration of carbon dioxide in the work area from exceeding safe levels. Some commercial grades of carbon dioxide may contain traces of heavy hydrocarbons, which can be left behind on the surface being cleaned. Abrasive particles originating in the cleaning equipment itself may need to be filtered out as well. The low temperature of the carbon dioxide stream can also induce moisture condensation on the part, which may be mitigated with hot plates, heat guns, heat lamps, or dry boxes. Ionization caused by the flowing gas can result in potentially damaging
