A small amount of single-cell protein has been produced using electricity and carbon dioxide alone. The researchers working on this believe the protein produced in this way could be further developed for use as food and animal feed. The protein can be produced anywhere that renewable energy, such as solar energy, is available.
Currently, the production of one gram of protein takes around two weeks, using laboratory equipment that is about the size of a coffee cup. To commercialise the product, it needs to be possible to be produced in far larger quantities. The researchers are beginning a pilot project to create enough material for fodder and food products to be developed and tested from the base material.
