Protein that lasts forever.

We believe that protein production shouldn’t be limited by our natural resources. We also think it shouldn’t burden our environment, either. The Solein bioprocess produces natural protein from CO2, water, and electricity. It’s a fully natural fermentation process, with an end product that looks and tastes just like wheat flour. And the best part? It won’t run out.


  • A unique single-cell protein – produced from water, CO2 and electricity
  • Fully natural fermentation process, similar to the production of yeast or lactic acid bacteria
  • Environmentally friendly

Fortum provides Solar Foods 100% renewable energy

Designed by Nature

Inspired by the cleanest air in the world and the purity of Finnish nature, the bioprocess of Solein unlocks the full power of natural protein production. Instead of causing CO2 emissions, it captures carbon dioxide and uses renewable electricity throughout its production process.

Discovered by Science

Producing Solein is entirely free from agriculture – it doesn’t require arable land or irrigation and isn’t limited by climate conditions. The original concept of Solein was born from a NASA space programme, and was further developed in the research projects of the Technical Research Centre of Finland Ltd and the Lappeenranta University of Technology (LUT).

In 2018, the ESA Business Incubation Centre in Finland requested Solar Foods to submit a proposal for food production in space conditions. The goal of this cooperation is to develop a system for producing natural proteins utilised in space flights to Mars.


  • Production not dependent on weather, irrigation or soil.
  • The end product looks and tastes like wheat flour,
    with 50% protein content and 5–10 % fat and 20–25 % carbs.
  • Starting in 2018, Solar Foods is participating in the ESA Business Incubation Centre Finland.
