Thorizon partners with molten salt energy storage provider

Wednesday, 30 April 2025

The two companies say that as part of the collaboration they will develop a joint offering for industrial energy user and work together on designing "conventional plant infrastructure, including a salt-to-salt heat exchanger and flexible power output solutions".

They will also explore joint efforts in developing a molten salt test loop to advance technology readiness.

Thorizon - a spin-off from NRG, which operates the High Flux Reactor in Petten - is developing a 250 MWt/100 MWe molten salt reactor, targeted at large industrial customers and utilities. The Thorizon One concept is unique in that the core is composed of a set of cartridges that is replaced every five to ten years.

The company says it is conducting pre-feasibility studies at three nuclear-designated sites in France, Belgium and the Netherlands, targeting construction by 2030.

Storabelle's system is based around the ability of molten salt to be able to store heat at temperatures of near to 600 degrees Celcius for days with minimal energy loss and can then "release it at the most valuable moment to optimise electricity generation and industrial processes".

Laure Claquin, Thorizon COO, said: "Through our engagements with industrial end-users and utilities, we recognise a strong demand for flexible power solutions. By integrating our molten salt reactor technology with Storabelle’s energy storage, we can deliver a highly competitive and scalable solution to meet evolving energy needs.”

Frédéric Pierucci, Storabelle co-founder, said: "This European collaboration expands our reach to industrial energy consumers. The Netherlands, with its strong reliance on renewables, presents a particularly promising market for our flexible energy storage solutions."
