Making protein from thin air – or at least from carbon dioxide captured from the air – is the mission of Solar Foods. Anthony Wright reports on the company’s groundbreaking progress.

Revolutionizing the Food Industry

While many technology companies are exploring carbon dioxide (CO2) as a feedstock for industrial applications, a few are focusing on food production. Solar Foods stands out among these pioneers as the first company aiming to create a protein-rich food product using captured CO2.

The Solar Foods Process

Solar Foods harnesses direct air capture (DAC) technology to extract CO2 from the atmosphere. This captured gas is then fermented with green hydrogen and microorganisms to produce a high-protein organism. The resulting product, Solein, is a nutrient-dense powder that can be easily incorporated into various food products.

Solein: The Future of Protein

The flagship product of Solar Foods, Solein, represents a significant leap forward in sustainable food production. By using CO2 and renewable energy, Solar Foods aims to reduce greenhouse gas emissions associated with traditional agricultural methods. Solein is designed to provide the nutritional value of conventional protein sources while minimizing the environmental impact.

Eyeing the US Market

In its strategic move towards expansion, Solar Foods has set its sights on the US market. This decision hinges on a key milestone achieved by Solein: receiving a Generally Recognised as Safe (GRAS) status from the US Food and Drug Administration (FDA) in September 2024. This approval clears the path for Solein to enter the market, making it available to consumers.

Challenges and Opportunities

The journey to commercializing Solein is not without challenges. Developing a novel food product from a unique raw material requires extensive research, regulatory approvals, and consumer acceptance. However, the potential benefits of Solein – including reduced strain on natural resources and decreased carbon footprint – present significant opportunities for the food industry.

Investing in the Future

Solar Foods is already listed on the Nasdaq in Finland, allowing the company to attract institutional investors. This funding support is crucial for continuing research and development, scaling production, and entering new markets like the US. By leveraging advanced technologies and innovative approaches, Solar Foods is poised to be a leader in sustainable food production.
