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 There is consensus among scientists that ocean sequestration of carbon dioxide is not a long-term plan to be relied on, but may solve immediate atmospheric concerns if implemented temporarily. Scientists believe that it is possible to engineer ways to discharge carbon dioxide at rates that resemble the natural fluctuation of carbon dioxide in the oceans. Ocean storage refers to the use of large water bodies and marine lifeforms to capture carbon by exploiting natural and geological mechanisms. Oceans cover slightly more than 70% of the total surface area of the Earth, and plays a major role in helping to stabilize
