Radiant (formerly Neamine) has announced the closing of a €2 million funding round, with participation from business angel networks Tiresias Angels and Selim Cherif. The company has also been selected to participate in Hexa's Carbon Zero acceleration programme.

Decarbonising industrial heat

Industrial heat accounts for more than 70% of total industrial energy consumption, but remains heavily dependent on fossil fuels. Radiant aims to address this challenge with a solar thermal solution designed for industrial applications. The system integrates next-generation heliostats, a proprietary receiver, and thermal energy storage systems, configurable for specific industrial needs.

Technology and applications

Radiant's technology is capable of supplying heat at temperatures between 200°C and 1,000°C, with thermal power outputs ranging from 2 to 50 megawatts. According to Alexandre Meurisse, CTO of Radiant, the technology is based on 15 years of research and development at the German Aerospace Center (DLR) and enables the production of hot air at temperatures exceeding 1,000°C.

Thomas Delhon, CEO of Radiant, added that the solution offers heat-intensive industries a practical way to reduce emissions while maintaining stable energy costs. Radiant's technology replaces fossil-fuel-based equipment with a solar heat source adapted to industrial processes. Companies in the asphalt, glass, and cement sectors have expressed interest in applying the solution to kilns and dryers.

Next steps

The new funding will support the construction of Radiant's first industrial demonstrator in Le Mans, to validate the scalability of the technology and the company's ability to efficiently deploy the solution at industrial sites. Participation in Hexa's Carbon Zero programme will provide further support for the development of the industrial solar thermal solution. The company plans to expand its activities internationally and scale the deployment of its technology to support the decarbonisation of industrial heat production.
