Malta Hochtemperatur Wärmepumpen Stromspeicher GmbH, a global manufacturer in long-duration energy storage, has announced the groundbreaking of the expansion of DLR’s test facility for thermal energy storage in molten salts (TESIS) for the full-scale qualification of the innovative, Alfa Laval-built heat exchangers, as part of their Store2REPower project.
DLR’s TESIS facility will be expanded to include a new two-story testing platform that is connected to the existing molten salt tanks and will house the new equipment, including two of the full-scale heat exchangers. Construction started with the initial groundbreaking on June 17th, 2024, and is expected to be completed together with commissioning in May 2025, so that qualification testing can begin in June 2025. The development and validation of the full-scale heat exchangers represent a very important step towards the deployment of the first of a kind commercial highly efficient heat pump electricity and heat storage system.
With among the best-available round-trip efficiencies, lowest system degradation, and longest plant life, Malta’s clean power and heat plant allows energy consumers to make up lost ground on decarbonisation goals.
