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 of water than the HFZ, the injection should happen below the HFZ and directly to the NBZ. In this case, liquid carbon dioxide will sink to the NBZ and be stored below the buoyancy and hydrate cap. Carbon dioxide leakage can occur if there is dissolution into pore fluid or via molecular diffusion. However, this occurs over thousands of years. Researchers have been able to show in lab and in small in situ experiments that carbon dioxide can be injected into oceans as rising or sinking plumes. The plume will sink if it is more dense than seawater. This should
