Finnish company, Solar Foods, is planning to bring to market a new protein powder, Solein, made out of CO₂, water and electricity. It's a high-protein, flour-like ingredient that contains 50 percent protein, 5–10 percent fat, and 20–25 percent carbs. It looks and tastes like wheat flour, and could become an ingredient in a wide variety of food products after its launch in 2021.
Solar Foods makes Solein by extracting CO₂ from air using carbon-capture technology, and then combines it with water, nutrients and vitamins, using solar energy to promote a natural fermentation process similar to the one that produces yeast and lactic acid bacteria.
Solein production is not dependent on arable land, rain, or favourable weather. The company is working with the European Space Agency to develop foods for off-planet production and consumption (the idea for Solein began at NASA).
