The Jimmy project

Jimmy was created in 2020 based on a dual realization: on one hand, industries need to change their source of heat, but there are few profitable decarbonized alternatives. On the other hand, nuclear fission allows for the production of low-cost decarbonized heat.

Jimmy's goal is to accelerate the transition to decarbonization as quickly as possible. After a concept maturation phase in 2021, Jimmy now relies on a determined multidisciplinary team and is reinventing the use of fission to decarbonize industry.

Our objective is to commission its industrial demonstrator by 2026 to realize its vision of a decarbonized and competitive industry in France.
