Blue Capsule is a high-temperature reactor (HTR) for industries that need a secure supply of heat, steam or electricity.

Volatile energy prices and fossil fuel supply shocks are breaking industry. The world needs sovereign energy supplies that cut our dependence on fossil fuels and decarbonize our economies.

Blue Capsule is a high-temperature reactor (HTR) for industries that need a secure supply of heat, steam, or electricity. This advanced nuclear tech is Europe’s only “tri-vector" solution at the high temperatures needed by energy-intensive industry. Hot air to 700°C, steam to 650°C, and 50 MWe of electricity as required. On site and on demand.

Blue Capsule combines the best of two mature technologies with existing supply chains: sodium-cooled reactors mastered by France over decades, and the high-temperature reactor created in Europe and now developed in China, Japan, and the United States. Our reactor uses low-enriched uranium (LEU) to less than 5%, avoiding fuel supply bottlenecks and making our technology export-friendly.

With TRISO fuel for maximum safety, Blue Capsule can be co-located with industrial sites for the production of fertilizers, soda ash and other chemicals, steel, synthetic fuels, cement, alumina, and hydrogen via high-temperature electrolysis (SOEC).

Supported by the French government, Blue Capsule Technology works hand in hand with the best of the French and European nuclear ecosystems.
