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
Ocean storage of carbon dioxide atmosphere, the resulting change in ocean pH would also be similar as ocean mixing would eventually absorb excess carbon dioxide. Dilute carbon dioxide injection requires injection at depths where carbon dioxide can be dispersed by ocean currents and ocean mixing. Upon injection, waters interact and mix based on density and dilute the concentration of carbon dioxide. Boat based carbon dioxide injection distributes low carbon dioxide concentrations in open waters while moving to increase carbon dioxide dispersal area. carbon dioxide dispersal via boat can also occur by a pipe attached to the ship injecting a dilute carbon dioxide mixture into the
