Finland-based deeptech Reduciner has raised €3.6 million in its first funding spherical, combining fairness backing from Voima Ventures, Lifeline Ventures, and the Mikko Kodisoja Basis.
The startup is targeted on fixing a persistent industrial problem of what to do with unavoidable carbon emissions. It emerged from VTT Technical Analysis Centre of Finland, certainly one of Europe’s main analysis establishments, in 2025, based by Johanna Grönroos, Eemeli Tsupari and Sampsa Vuori.
On the core of its strategy is a high-temperature thermochemical course of that converts captured carbon dioxide into carbon monoxide utilizing renewable electrical energy and biogenic carbon. Since carbon monoxide integrates simply into present industrial programs, corporations can undertake the answer with out costly infrastructure overhauls.
“On a world scale, CO2 emissions from the lime and cement business are greater than these from aviation and marine transport mixed. With this know-how, it’s potential to switch fossil fuels of those industries website by website, relying on the supply of inexperienced electrical energy and grid connection, whereas additionally bettering price competitiveness,” says Tsupari.
Competitors within the carbon-to-fuel sector is rising throughout Europe, with gamers like Elyse Vitality, Liquid Solar, and Electrochaea changing CO₂ into fuels utilizing hydrogen or biocatalysis, whereas OXCCU focuses on direct jet gas synthesis and Synhelion makes use of solar-driven processes.
Reduciner improves economics by larger effectivity and worthwhile co-products akin to activated carbon, decreasing reliance on subsidies or on costly inputs like hydrogen.
“Most applied sciences that search to switch fossil fuels with extra sustainable ones require rebuilding of infrastructure. Reduciner’s know-how converts CO2 into CO, which is suitable with present equipment, permitting the answer to be deployed sooner and extra cost-efficiently,” says Johanna Grönroos, co-founder and CEO of Reduciner.
“What makes Reduciner stand out from different deep tech corporations aiming to develop sustainable gas alternate options is that with our course of, the sustainability impacts are reached profitably from the very starting,” Grönroos provides.
Reduciner is focusing on hard-to-abate sectors akin to cement, metal, pulp, and lime, industries the place emissions are sometimes unavoidable. In lime manufacturing, for instance, captured carbon dioxide could be transformed and reused as gas inside the identical course of, successfully making a closed carbon loop. Given the worldwide scale of those industries, the potential influence on emissions discount is substantial.
“Reduciner stands out as a result of it’s already doing what many industrial local weather corporations can to this point solely promise on paper: validating the know-how whereas advancing industrial discussions and fixing actual prospects’ issues. For Voima Ventures, that mixture issues. When you’ve gotten breakthrough science, early proof that the answer works, and ongoing negotiations that present clear market pull, you’ve gotten the muse of a really compelling firm. That is the explanation we at Voima Ventures are backing the staff,” says Pontus Stråhlman, Companion at Voima Ventures.
“What’s uncommon about Reduciner is how a lot is already in place on the spin-out stage — superior industrial discussions, a primary deployment mannequin with companions, and a staff that spans the complete stack from science to finance. We’re excited to be a part of this from the beginning,” says Juha Lindfors, Managing Companion at Lifeline Ventures.
The funding will help the development of its first industrial-scale pilot, a 1MW facility in Finland, as the corporate strikes towards industrial deployment, adopted by worldwide enlargement earlier than 2030.
