Calogena

A subsidiary of the Gorgé industrial group, Calogena offers an innovative and promising solution for decarbonizing and extending district heating networks. Calogena is developing a small modular reactor (SMR) specially designed for district heating. This project represents a major step forward in the decarbonization of district heating. The Calogena module, with a thermal capacity of 30 MW, can supply energy to 20,000 low-carbon households. Calogena is supported by France 2030. The French Nuclear Safety Authority (ASN) has ranked Calogena at the highest level of maturity among French SMRs. The French High Commissioner for Atomic Energy (HCEA) ranked Calogena at the forefront of French SMRs in November 2024.
