Radiant (formerly Neamine), a European climate technology company building solar thermal solutions for decarbonising industrial heat, has raised €2 million in a seed funding round while being selected to participate in Hexa’s Carbon Zero acceleration programme a climate-focused cohort designed to back breakthrough technologies that can economically replace legacy carbon systems. The funds will help advance Radiant’s next-generation industrial heat platform and support construction of its first industrial demonstrator in Le Mans to validate scalability and operation at industrial sites. The round was led with participation from Tiresias Angels and investor Selim Cherif, underscoring early confidence in Radiant’s mission to cut fossil fuel reliance in heat-intensive sectors. Industrial heat accounts for a large share of energy consumption and emissions, especially in materials and process industries where traditional gas burners and oil-fired boilers remain dominant. Radiant’s solar thermal system combining next-generation heliostats, a proprietary receiver and thermal storage can deliver high-temperature heat up to 1,000 °C for industrial furnaces, kilns and dryers, while helping companies reduce carbon emissions and manage energy costs. Radiant builds on 15 years of research at the German Aerospace Center (DLR), and its technology addresses a longstanding gap in economically competitive low-carbon industrial heat solutions. With this funding and support from Hexa’s Carbon Zero programme, Radiant plans to expand demonstration deployments and pursue international expansion, contributing to broader industrial decarbonisation efforts across Europe and beyond.
