Blue Capsule and Jimmy engage with Poland’s HTR community

High-temperature reactor technology in the spotlight again with a new round of exchanges between French and Polish experts.

APRIL 2025 | On 1-2 April, Blue Capsule Technology and Jimmy were pleased to take part in the French-Polish Industry Days held in Katowice, Poland, and organised by GIFEN and IGEOS (Izba Gospodarcza Energetyki i Ochrony Środowiska).

The discussions gathered 90 companies, over 110 attendees, and enabled more than 200 B2B meetings for French industry representatives with 60 Polish companies. This exchange again underscored a common need to reduce dependence on imported energy, reinforce sovereignty, and decarbonise our industries.

In the case of Poland, there has been impressive progress on high-temperature reactors (HTRs) with the country’s HTGR-POLA programme, under the leadership of the National Centre for Nuclear Research (NCBJ).

On the French side, work is also well under way, following a 2016 French government report identifying the need for a fleet of HTRs to supply high-temperature industrial heat and steam. This continues to guide the sector’s roadmap toward commercial deployment, with additional investment from Bpifrance and equally valuable support from the CEA.

So naturally, on 2 April in Katowice, Blue Capsule and Jimmy were delighted to go deeper into the topic during a special session on HTR tech. And both companies were clear on what’s at stake for industry: reliable, low-carbon heat in energy-intensive sectors that can’t always rely on electrification.

Jimmy presented its work on compact heat generators (20-60 MWth) aimed at industries like chemicals, food and beverage, and pulp and paper. Based on proven technology with passive safety features, the reactor will deliver competitive low-carbon steam, or any other heat transfer fluid, in the range of 100°C to 500°C.

Blue Capsule Technology provided details on its 150 MWth solution – a reactor that can provide heat to 700°C, steam to 650°C, and 50 Mwe as required. This solution is ideal for industrial processes where electrification is neither practical nor competitive, and tailored towards ammonia and soda ash production, alumina refining, hydrogen production using SOECs, or cement production using activated clay.

The call to action is clear: energy sovereignty and industrial decarbonisation are European – and global – issues. France and Poland both have active HTR initiatives, and early co-operation across countries will be essential to build the capabilities Europe needs.

Our thanks to GIFEN and IGEOS for their leadership in strengthening French-Polish industrial partnerships, and to the HTR community in Poland for the genuine interest shown during our exchanges.
