The collaboration is setting out to commercialise the hydroxide salt energy storage solution in a move that builds on the success of the Molten Salts Storage (Moss) project in Denmark.
The Moss demonstrator plant project consortium, inaugurated in April 2024, proved the concept of storing renewable energy in molten salt at temperatures up to 600°C.
Captured energy is discharged when molten salt is pumped from a storage tank to a heat exchanger, producing steam for industrial use. This offers a green and reliable solution for industrial heat electrification, supporting the decarbonization of process heat.
Benoît Martin, advance engineering manager at Sulzer, explained the next steps: “With the Moss plant providing good results since its inauguration in April 2024, we’re now working with Hyme Energy to further optimise the system, improve the competitiveness of the solution and establish a strong supply chain. Sulzer’s vertical turbine pumps are crucial for moving molten salt around the system, so we are also focusing on achieving material and technical advancements to extend service life, boost performance and add value.”
“Our technology is designed to integrate with existing infrastructure, making adoption easier for industries looking to transition to sustainable energy. For us at Hyme, it is key to work with established partners like Sulzer. By combining our strengths, we can accelerate progress and bring this solution to market faster,” said Ask Emil Løvschall-Jensen, CEO and co-founder of Hyme Energy.
Benoît concluded: “We’re always ready to collaborate on new technologies. Energy storage with molten salts is a tantalising opportunity to help decarbonise industry and accelerate the energy transition, whether in terms of heat recovery, renewable energy storage, or small modular reactors (SMRs). It’s exciting to be working with Hyme Energy to further validate this innovative technology for the benefit of all.”
