Week 10 of 2025
Three nuclear energy innovation news!
🍩 Renaissance Fusion (France) raises a €32m Series A1 round led by Crédit Mutuel Impact with participation from Lowercarbon Capital. The company's approach utilizes high-temperature superconducting magnets directly deposited and patterned onto cylindrical surfaces to simplify the stellarator concept. Additionally, they plan to employ liquid lithium layers with suspended molten lead spheres for the triple purpose of fuel breeding, neutron shielding, and heat extraction. They aim to achieve a full-scale stellarator by the early 2030s.
🛩️ AeroFuse (US) raises a $800k Pre-Seed round from various backers including The Veteran Fund, DraperU Ventures, Techstars, and IAI North America. Their goal is to unlock the power of fusion to reduce aviation fuel cost, emissions, and enable extreme endurance for net-generation defense aircraft. Not many details are available about the company, with a LinkedIn banner that states "stealth for now" and a webpage that indicates "coming soon". AeroFuse team, if your read this: reach out!
♨️ Steady Energy (Finland) raises a €22m round led by 92 Ventures, part of its Series B. The company is developping a 50 MWth Light Water Reactor (LDR-50) which operates at low pressure and low temperature. It is designed exclusively for district heating and industrial applications. The funds will be used to commence construction of a full-scale pilot plant later in 2025.
