Industrial Heat • Decarbonization • Energy Sovereignty

Stable industrial heat beyond fossil fuel volatility.

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.

Industrial heat is becoming unsustainable

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.

+195%

Gas price swing observed in 2025.

+355%

Increase in European carbon pricing in past 5 years.

30,000 TWh

Industrial heat demand exposed to fossil fuel risks.

80%

Industrial heat still relies on fossil energy sources.

SIMR‑200:
Designed for industrial heat - No R&D - Limited exclusion zone

Unlike many small modular reactor concepts primarily targeting electricity generation, SIMR‑200 is engineered around industrial thermal needs from day one.

Maximum system simplification

Maximum system simplification by eliminating chemistry systems and relying on in-core control.

Steady state operations

Simplified architecture and enhanced reliability.

Passive systems

Minimized active systems and optimized redundancy.

Constructability

Designed for repeatable construction, not bespoke mega-projects, through offsite assembly and O&G approach.

Maintainability

Optimised for maintainability, not on-site complexity.

Reactor/Industrial use decoupling

Improved safety, simplified licensing, and customer-side process optimisation.

One output. Multiple industrial uses.

FlowThermy can support a broad range of thermal applications through superheated water and steam production.
