Solar Foods has locked in €77.8M ($89.6M) from Business Finland to build its second industrial-scale protein factory, a financing decision that lands just as the Finnish biotech awaits EU novel food clearance for Solein, its gas-fermented protein made from carbon dioxide.
The package breaks down into a €39.6M grant and a €38.1M R&D loan. Both sit inside the EU Commission's hydrogen-based Important Project of Common European Interest (IPCEI) scheme — a category Brussels uses to back technologies it deems strategically important to the bloc's industrial future.
The money is earmarked for Factory 02 in Lappeenranta, Finland.
That facility is expected to come online in 2028 with an annual capacity of 12,800 tonnes of Solein, produced at a target cost of €4.30 to €5.20 per kilogram of protein. For context, Solar Foods' current demo plant in Vantaa is set to reach just 230 tonnes this year. Factory 02 represents a roughly 55-fold jump in output.
What Solein actually is
Spun out from VTT Technical Research Centre of Finland and LUT University in 2017, Solar Foods grows microbes in liquid by feeding them CO2, hydrogen and oxygen instead of sugar. The result is dried into a pale yellow powder that's 78% protein, 6% fat and 10% dietary fibre, with a macronutrient profile the company compares to dried soy or algae.
The pitch is resource minimalism. No farmland. No irrigation. No fertilisers or pesticides. According to the company, Solein production generates emissions equal to about 1% of conventional meat and 20% of plant proteins. Solar Foods estimates that swapping a kilo of whole milk for Solein could save around 20kg of CO2e.
Those numbers come from the company itself, which is worth flagging. Independent life-cycle assessments of gas fermentation are still thin on the ground.
The regulatory map
Solein already has regulatory clearance in Singapore, where it has appeared in ice creams, mooncakes and dairy-free lattes. In the US, Solar Foods has self-affirmed the ingredient as Generally Recognized as Safe (GRAS) and recently launched it through Ambrosia Collective's protein powder, with supply agreements signed with Superb Food and KelpEat, among others.
EU approval is the next domino. Solar Foods expects it this year.
That timing matters. Novel food authorisation in Europe is famously slow — The Protein Brewery's recent Fermotein clearance took six years from application to approval. A faster path for Solein would suggest the EU's regulatory framework is starting to catch up with the pace of fermentation innovation, even if only marginally.
The precision fermentation angle isn't entirely new territory for us—we put together a deep dive on mycoprotein's muscle-building potential that shows how fungal fermentation has already proven itself at scale, which makes Solar Foods' timeline feel even more sluggish by comparison.
Why this matters beyond Finland
Business Finland has now committed up to €110M in grants to Solar Foods through 2035, having previously seeded Factory 01 with €33.6M in 2022. The company has separately raised around €83M in equity and debt. That's a stack of public-private capital being placed on the bet that gas fermentation — not just plant-based reformulation — is where the protein conversation goes next.
The broader category is moving. VegOut previously covered a LanzaTech biofoundry deal in Copenhagen that points in a similar direction: microbes turning industrial gases into food, fuel and materials.
The honest question is whether the unit economics hold. At €4.30-5.20 per kilo of protein, Solein has to compete not with premium meat alternatives but with commodity protein ingredients like soy and pea isolates, which trade well below that range. Scaling to 12,800 tonnes is the test of whether the technology can earn its place on a balance sheet, not just a sustainability report.
That's the bet Business Finland just underwrote.
