Finnish deep-tech startup Reduciner has successfully secured €3.6 million in its initial funding round to commercialize its groundbreaking carbon conversion technology. Originating from the VTT Technical Research Centre of Finland, the company aims to help heavy industries reduce emissions by turning captured carbon dioxide into valuable assets. The investment round was led by Voima Ventures and Lifeline Ventures, with participation from the Mikko Kodisoja Foundation.


An Innovative Approach to Carbon Conversion

Reduciner is pioneering a high-temperature thermochemical process that transforms captured carbon dioxide into carbon monoxide using renewable electricity and biogenic carbon. This innovation allows for the indirect electrification of industrial combustion processes, enabling a significant reduction in global CO2 emissions. The resulting carbon monoxide is a key component for producing sustainable fuels and chemicals on a large scale.

A significant advantage of Reduciner's technology is its compatibility with existing industrial infrastructure, eliminating the need for costly system overhauls. This feature allows for faster and more cost-efficient deployment compared to other sustainable fuel technologies. The process is designed to be economically viable from the outset, a crucial factor for widespread industrial adoption.

Economic Viability and Strategic Co-Products

The system's profitability is enhanced by the production of activated carbon as a valuable co-product. This material is widely used for water and gas purification, with demand expected to grow due to tightening environmental regulations. This dual-product output improves the overall process economics, reducing reliance on policy incentives or volatile fossil fuel prices.

Investors have noted the company's advanced stage, highlighting its validated technology and clear market demand demonstrated through ongoing commercial discussions. The combination of breakthrough science and proven market pull forms a strong foundation for the company's future success. VTT also contributed to the new venture by transferring the underlying technology and intellectual property rights as an in-kind investment.

Targeting Hard-to-Abate Industries

Reduciner’s solution is particularly well-suited for hard-to-abate sectors such as the lime, cement, steel, and pulp industries. These sectors face challenges with unavoidable process emissions, which this technology can directly address. By converting captured emissions into usable fuel, the system enables a circular use of carbon within the same industrial facility.

For example, in the lime industry, CO2 captured from a kiln can be processed and reused as fuel in the same kiln, effectively closing the carbon loop. This not only reduces emissions but also improves cost-competitiveness by replacing expensive fossil fuels. The global scale of emissions from the lime and cement industries presents a vast potential for this technology's impact.

Future Outlook and Commercialization Plans

The newly acquired funding will be instrumental in advancing the technology towards full commercialization. Reduciner plans to construct its first industrial-scale pilot, a 1MW facility in Finland, to demonstrate its capabilities. This step is critical for validating the process at a commercial level and paving the way for broader implementation.

Following the initial deployments in Finland, the company has set its sights on international expansion before 2030. The technology, which is based on several years of research and pilot-scale testing at VTT, is designed for site-by-site implementation. This flexible approach allows industries to transition away from fossil fuels as the availability of green electricity increases.


With its €3.6 million in funding, Reduciner is poised to make a significant contribution to industrial decarbonization. The company's innovative, economically viable, and easily integrated technology offers a practical pathway for heavy industries to reduce their carbon footprint. This strategic investment marks a pivotal moment in the journey to turn industrial emissions into a valuable resource for a sustainable future.
