Solar Foods to commence hydrogen-to-protein pilot


Finnish company, Solar Foods, in an interview with Greentech Media (GTM), shared plans to start making a kilo of food a day from nothing but electricity, water and air.

Next month, the company will electrolyze water to produce hydrogen (H2) that is used, along with carbon dioxide (CO2) and small amounts of trace elements, to feed microbes.The microbial cells, with a protein content of up to 60% and an amino acid composition similar to soybeans or algae, will be heat-treated to form a fine powder, similar in appearance and texture to dried milk.

Solar Foods CEO Pasi Vainikka said the product could be used to enrich widely consumed human foods such as bread or pasta. 

The company’s €1m ($1.1m) pilot plant, near the Finnish capital of Helsinki, is intended as a precursor to commercial-scale operations that could commence as early as the beginning of 2021, depending on European Food Authority (EFA) approval.
