Solar Foods

The company's core business revolves around the production and commercialization of Solein®, a novel single-cell protein. This protein is created through a bioprocess using a natural, unmodified microbe. The process, likened to fermentation in breweries, feeds the microbe with CO2, hydrogen (produced by splitting water with renewable electricity), and mineral nutrients. This method is significantly more resource-efficient than traditional agriculture, requiring a fraction of the land and water. The resulting product is a fine, mustard-colored powder rich in protein.

Solein is a highly versatile food ingredient, composed of up to 78% protein, along with fats, dietary fibers, and minerals. It contains all nine essential amino acids and is a source of iron and B vitamins. Its neutral taste allows it to be incorporated into a vast range of food products, from dairy and meat alternatives to noodles and ice cream, without altering their flavor profile. The business model is twofold: supplying Solein as a B2B ingredient to global food manufacturers and licensing its patented hydrogen fermentation technology platform to other producers. Key partners include the Fazer Group for research collaboration and Ajinomoto for developing Solein-based products. The company is also collaborating with flavor manufacturer Sensapure Flavors to develop product concepts for the US market.

Solar Foods has achieved significant milestones, including raising over $52.4 million in funding from investors like Lifeline Ventures and receiving substantial grants from entities such as Business Finland and the European Union. In 2022, Singapore became the first country to grant novel food approval for Solein, allowing for its commercial sale. A major achievement was the launch of 'Factory 01' in Vantaa, Finland, in spring 2024, the world's first commercial-scale facility producing food from air. This facility serves as a demonstration plant to prove the technology's scalability, with plans for much larger factories in the future. The company has also gained recognition from NASA's Deep Space Food Challenge.
