What are the uses of CO2?

On this page we describe some industrial uses of carbon dioxide. To start, it is used for cooling (as dry ice) and refrigerating, in fire extinguishers (as it blocks burning fire from oxygen it needs), for inflating life jackets, to create bubbles during foaming rubbers, plastics, and concrete, to preserve food in food packaging, in production of carbonated soft drinks and alcohols with bubbles, and for promoting the growth of plants in greenhouses (a process called CO2 enrichment).

CO2 for greenhouses

CO2 enrichment is very important as the amount of carbon dioxide in the outside air is only 420 ppm (parts per million) or 0.042%. This amount is more or less sufficient for most plants to grow outdoors, however when placing a lot of plants together in indoor environments like greenhouses, the carbon dioxide level drops quickly as plants are using it for photosynthesis (in fact, “eating” it). Greenhouses are our first target clients.

CO2 for synthetic fuels

CO2 is one out of two main components to create synthetic fuel. The second one is hydrogen. This is how carbon-free energy is converted into carbon-neutral high-energy-density fuels.

Such synthetic fuels can immediately replace conventional fuels without any of the upgrades for existing vehicles.
Thus, they will be critical to speed up transformation of the automobile sector and make it carbon neutral.

CO2 as a polar solvent

And, recently, liquid CO2 is being used as a polar solvent for extraction of chemicals in cosmetics and pharma industrial applications.

It is called supercritical fluid extraction. Unlike many popular solvents, supercritical carbon dioxide is non-flammable. Its solvation power can be adjusted by varying the density of the fluid and CO2 leaves almost no residue in extraction products compared to conventional organic solvents. It is widely available in a very pure form and in commercial quantities and is also 100% inert and non-toxic. And last, but not least, it has a relatively low cost.

Enhanced Oil and Gas Recovery

Another important CO2 use is a process known as EOR/EGR when it is used to help extract shall oil and gas from wells in by injecting the carbon dioxide into underground. It is an important industrial application, as many million tons of CO2 are pumped into such wells each year.
