Reduciner, a deep-tech startup originating from VTT Technical Research Centre of Finland, is commercialising a new high-temperature technology that enables companies to turn captured carbon dioxide (CO₂) into e-fuels.
The startup raised €3.6 million in its first round of funding from Voima Ventures, Lifeline Ventures, and Mikko Kodisoja Foundation. The plan is to build Reduciner’s first industrial-scale pilot, a 1MW facility in Finland, to begin the commercialisation of its technology.
Reduciner’s technology involves a proprietary thermochemical process that converts CO₂ into carbon monoxide (CO), using renewable electricity and biogenic carbon. The carbon monoxide provides feedstock for e-fuels and other industrial applications. Since CO is already compatible with existing industrial systems, the solution allows companies to reduce emissions without costly infrastructure changes.
The technology is based on several years of research at VTT and has been validated through pilot-scale testing. The commercialisation phase began in 2026 and includes small-scale demonstration installations, with the first industrial-scale deployments in Finland, and broader international expansion targeted before 2030.
