Radiant (formerly Neamine) has been selected to participate
in Hexa’s Carbon Zero acceleration programme and has closed a €2 million
funding round, with minority participation from the business angel networks
Tiresias Angels and Selim Cherif.
Industrial heat accounts for more than 70 per cent of total
industrial energy consumption, yet it remains largely dependent on fossil
fuels. One of the main reasons is the limited economic competitiveness of
low-carbon heat solutions, which often requires industrial operators to balance
cost pressures with decarbonisation objectives.
Radiant is addressing this challenge by developing a solar
thermal solution tailored to industrial applications. Its system integrates
next-generation heliostats, a proprietary receiver, and thermal energy storage
to deliver configurations adapted to specific industrial needs.
The 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, while maintaining a high
degree of operational control.
According to Alexandre Meurisse, CTO of Radiant, the
company’s core technology builds on 15 years of research and development
conducted at the German Aerospace Center (DLR) and enables the production of
hot air at temperatures exceeding 1,000°C, above current industry standards.
Thomas Delhon, CEO of Radiant, added that the solution
offers heat-intensive industries a practical way to reduce emissions while
maintaining stable energy costs.
In practice, Radiant’s technology replaces
fossil-fuel-based equipment such as gas burners and oil-fired boilers with a
solar-based heat source adapted to industrial processes. Companies in sectors
such as asphalt, glass, and cement have expressed interest in applying the
solution to equipment, including kilns and dryers.
The new funding will support the construction of Radiant’s
first industrial demonstrator in Le Mans, intended to validate the scalability
of the technology and the company’s ability to deploy the solution efficiently
at industrial sites. Participation in Hexa’s Carbon Zero programme will also
provide Radiant with additional support as it continues to develop its
industrial solar thermal solution.
Over time, the company plans to expand its activities
internationally and scale the deployment of its technology to support the
broader decarbonisation of industrial heat production.
