FlowThermy develops the SIMR‑200, a Small Industrial Multipurpose Reactor specifically designed for industrial heat production. Our mission is to provide predictable, low‑carbon thermal energy for energy‑intensive industries facing fuel price volatility, carbon pressure and geopolitical uncertainty.
A large share of industrial heat remains dependent on fossil fuels. Energy price volatility, decarbonization requirements and increasing carbon costs are becoming structural challenges for industrial competitiveness.
Gas price swing observed in 2025.
Increase in European carbon pricing in past 5 years.
Industrial heat demand exposed to fossil fuel risks.
Industrial heat still relies on fossil energy sources.
Unlike many small modular reactor concepts primarily targeting electricity generation, SIMR‑200 is engineered around industrial thermal needs from day one.
Maximum system simplification by eliminating chemistry systems and relying on in-core control.
Simplified architecture and enhanced reliability.
Minimized active systems and optimized redundancy.
Designed for repeatable construction, not bespoke mega-projects, through offsite assembly and O&G approach.
Optimised for maintainability, not on-site complexity.
Improved safety, simplified licensing, and customer-side process optimisation.
FlowThermy can support a broad range of thermal applications through superheated water and steam production.
FlowThermy aims to help industries decarbonize while protecting competitiveness through resilient, predictable and low‑carbon thermal energy.
