Reduciner, a Finnish startup emerging from VTT, has raised €3.6 million to scale up its innovative process that converts captured CO2 into fuel and industrial feedstocks, offering a new pathway for heavy industry to manage emissions more economically and sustainably.
Finnish startup Reduciner has raised €3.6 million in its first funding round to push a technology that turns captured carbon dioxide into fuel gas and industrial feedstocks, a development that could offer heavy industry a more commercially useful route for carbon management than storage alone.
The company, which emerged from Finland’s VTT Technical Research Centre, is developing a high-temperature thermochemical process that converts CO2 into carbon monoxide. That output can then be used as a building block for synthetic fuels and chemicals, including methanol, while also fitting into existing industrial value chains with relatively limited changes to infrastructure, according to the company.
Voima Ventures, Lifeline Ventures and the Mikko Kodisoja Foundation participated in the round. VTT has also transferred the underlying technology rights and intellectual property to the new business as an in-kind investment, underscoring the research base behind the commercial push.
Reduciner says the appeal of the process lies in both emissions reduction and economics. By producing activated carbon as a co-product, it aims to improve project returns and reduce dependence on public subsidy, an important consideration for industrial decarbonisation projects that must compete on cost as well as carbon performance.
The technology is being positioned for hard-to-abate sectors such as cement, lime, steel and pulp, where process emissions are difficult to eliminate. In such industries, captured CO2 could be recycled back into operations rather than treated purely as waste, creating what the company describes as a circular carbon pathway.
Johanna Grönroos, Reduciner’s co-founder and chief executive, said the company’s approach is intended to avoid the kind of wholesale infrastructure replacement often required by other clean-fuel technologies. The startup says the process has already been validated at pilot scale and is now moving into commercialisation.
The next milestone is an industrial pilot plant in Finland with a planned capacity of 1MW. Initial deployments are expected in Finland, with broader expansion targeted before 2030, as the company looks to demonstrate that captured carbon can become a usable industrial asset rather than a liability.
