Planta Protein Powder Uses Solar Foods Solein Air Protein Made from CO2 and Electricity

Ambrosia Collective has launched a new protein powder called Planta that uses Solein, an air protein from Finnish startup Solar Foods. Solein is made by fermenting a naturally occurring microbe with carbon dioxide and electricity, producing a protein source that requires far less land than crops or livestock. The powder comes in a Salted Caramel Cold Brew flavor with 20 grams of protein and zero sugar per serving. This approach to protein production separates food supply from traditional agriculture. It uses fermentation to turn captured CO2 into a usable ingredient, which could reduce the environmental footprint of protein powders and supplements. The product is now available in the US market. For anyone tracking low-carbon food tech, this is a concrete example of precision fermentation moving beyond niche ingredients into mainstream consumer products. The key question is how scalable the production process is and what the energy cost per gram of protein looks like at commercial volume.
