Industrial heat for the 21st century
Blue Capsule, the small modular reactor designed for flexible decarbonisation — high-temperature heat, steam, and electricity for industry.
Industrial heat: a strategic decarbonisation opportunity
10%
Industrial heat above 400 °C accounts for 10% of global CO₂ emissions — making its decarbonisation a strategic opportunity for industry.
75%
With fossil fuels providing at least 75% of industrial heat, industries face soaring costs and emissions. A new solution is essential.
Our reactor
Existing supply chain – decades of French expertise
The French nuclear industry has accumulated decades of recognised expertise in sodium-cooled reactor technologies. What began as an innovative approach—combining compact design with high performance—has become a mainstream cooling solution for reactors across Europe, North America, and Asia.
France remains a global centre of expertise in this field, supported by a mature and reliable supply chain. Today, sodium-cooled reactors are deployed not only in France, but also in advanced projects in the United States and beyond, demonstrating the worldwide relevance of this proven technology.

The high-temperature reactor (HTR) – proven European tech
High-temperature reactors (HTRs) typically operate at over 800 °C—well above the range of conventional nuclear plants. This proven European technology dates back to 1959, when German scientists began developing prototypes in Jülich. The first European HTR, the Dragon project in the UK (1964), built on German engineering and scientific expertise.
Subsequent milestones, such as the AVR project in 1966, advanced the technology further, targeting the needs of energy-intensive industries such as chemicals and heavy manufacturing. This history laid the foundations for Europe’s leadership in HTRs—heritage on which Blue Capsule builds today.

TRISO – the world’s most robust nuclear fuel
In a Blue Capsule SMR, core melt is designed to be virtually impossible. This is achieved through the use of TRISO—the most robust nuclear fuel available—operating in a naturally circulating sodium pool at atmospheric pressure.
TRISO fuel consists of microspheres of fissile material, such as uranium, embedded in a graphite matrix. It can safely withstand operating temperatures of 800–1000 °C, and remains stable up to extreme conditions near 1800 °C. This resilience gives TRISO fuel unique performance and safety characteristics, enabling the high-temperature outputs required by industry.

A competitive cost target: €50/MWh
Blue Capsule targets an industrial heat cost of around 50 €/MWh. In the European Union, natural gas and coal fall under the EU Emissions Trading System (EU ETS), which applies a rising price to every tonne of CO₂. By 2035, coal will carry an additional 52–78 €/MWh in carbon costs, and natural gas 31–47 €/MWh (World Energy Outlook 2024, IEA + internal calculations).
In short, Blue Capsule’s nuclear heat will be cheaper than fossil heat — with a stable price, shielded from both fuel market volatility and the EU’s steadily rising carbon price.

No water required – ideal for arid environments
The Blue Capsule design delivers sufficient power for an industrial site in a compact underground installation. The system is cooled by ambient air, requiring no water—a key advantage in arid or water-stressed environments.
By producing electricity, process heat, and steam simultaneously, a single Blue Capsule unit can meet the needs of an isolated energy community, providing a reliable “energy oasis” even in the driest locations.
