Solar Foods
Finnish startup making Solein, a protein powder grown from air, CO2, and bacteria.
On the record
Checkpoint: H1 2026 earnings release covering Factory 02 FID language and offtake progress
The call
Solar Foods has real regulatory ground others lack, but it is still pre-revenue at scale and waiting on a Factory 02 decision while peers like Arkeon and Calysta have already stumbled.
Solar Foods grows protein using bacteria, electricity, and carbon dioxide instead of traditional farming. The company has won regulatory approvals in Singapore and the United States and owns a unique strain of bacteria that competitors would struggle to copy, which creates real protection. However, Solar Foods has almost no sales yet (earned only 0.12 million euros in 2025 while losing 11.5 million euros), and the biggest hurdle is not rival companies but money: the company must decide whether to build and fund a second factory, and several similar startups (Arkeon, NovoNutrients, Calysta) have failed or retreated in recent years as funding dried up. The one thing that could change everything is whether the customer interest Solar Foods claims in preliminary talks turns into signed, paid contracts that prove the business actually works at scale.
Why
01
AI pressure: None apparent. Gas fermentation protein production has no meaningful AI exposure on either side of the ledger yet. Could AI do the core job? Unlikely.
02
Bigger players: None apparent. No large food or biotech company has entered gas-fermentation protein at scale; the pressure comes from sector-wide capital flight instead. Could a giant copy it? Probably.
03
What protects it. Singapore and US regulatory approvals plus a proprietary Xanthobacter bacterial strain that competitors cannot simply copy.
What would change this call
Whether Solar Foods announces a final investment decision on Factory 02. Shows if financing and commercial commitments are firm enough to scale past Factory 01.
Whether any of the 6,500-7,650 tonnes/year LOIs convert to binding supply contracts. Shows whether customer interest is real demand or non-binding intent.
Whether EU novel food approval is granted or rejected in 2026. Determines if Solar Foods can sell Solein in its largest target market.
Whether any of the 6,500-7,650 tonnes/year LOIs convert to binding supply contracts. Shows whether customer interest is real demand or non-binding intent.
Whether EU novel food approval is granted or rejected in 2026. Determines if Solar Foods can sell Solein in its largest target market.

Questions people ask
- Is Solar Foods profitable in 2025?
- No. Solar Foods reported statutory net sales of EUR 123,595 for full-year 2025 against an operating loss of EUR 10.4 million and a net loss of EUR 11.5 million, per its own H2 2025 results published 2026-06-20. The company remains pre-revenue-at-scale while it awaits a Factory 02 investment decision.
- Who owns Solar Foods and is it publicly traded?
- Solar Foods Oyj listed on Nasdaq First North Growth Market Finland on 2024-09-10 under ticker SFOODS without a share issue. Early investors include Lifeline Ventures, VTT Ventures, and Fazer Group. In January 2026, industrial equipment maker GEA made a minority investment of about EUR 9.46 million.
- Could AI replace what Solar Foods does?
- No. Solar Foods runs a physical gas-fermentation manufacturing operation, growing Xanthobacter bacteria on CO2 and hydrogen in bioreactors, plus regulatory affairs work; these are physical assets and government approvals, such as its 2022 Singapore approval and November 2024 US GRAS status, that AI software cannot replicate or take over.
- Is joining Solar Foods a safe career move right now?
- It carries execution risk. As of 2026-06-17, Solar Foods had 56 employees, a EUR 11.5 million FY2025 net loss, and an undecided Factory 02 final investment decision, gating its whole growth plan. Peer gas-fermentation firms Arkeon and NovoNutrients failed in 2025, showing sector-wide capital stress.
- Who is Solar Foods' biggest competitor?
- Its closest peers are other gas-fermentation protein startups: Calysta, Air Protein, Deep Branch, Unibio, and Aerbio. Notably, Calysta wound down its US and UK R&D labs and pilot plants in November 2025 to focus purely on manufacturing, while peers Arkeon and NovoNutrients failed the same year, per AgFunderNews reporting.
- When will Solar Foods build its second factory?
- Solar Foods chose Selkaharju, Lappeenranta as the Factory 02 site on 2025-12-16, targeting 6,400 tonnes/year initial capacity and up to 12,800 tonnes/year long term. As of 2026-06-17, a EUR 77.8 million Business Finland grant and loan package was awarded, but explicitly conditional on a still-pending final investment decision.
