The two companies previously collaborated in the MOSS demonstrator plant project consortium, inaugurated in April 2024, which 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 cost-competitive, green and reliable solution for industrial heat electrification, supporting the decarbonization of process heat.

Benoît Martin, Advance Engineering Manager at Sulzer explains 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 optimize 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.”
