Malta Inc. announced a partnership with Siemens Energy to co-develop the commercial design of innovative new turbomachinery components for Malta’s long-duration energy storage system.
Malta’s Pumped Heat Energy Storage (PHES) system uses components based on industry-proven thermo-mechanic systems adapted for a novel energy storage application. This storage is charged with electricity from any source to be stored as thermal energy, and dispatches at discharge electricity and heat on demand. The partnership will focus on the development of innovative heat pump and heat engine components to support a utility-scale 100MW system for 10-200 hours of storage and further scaling to the GW power range.
In addition to dispatchable electricity and heat, the components in co-development will support a range of services that the Malta pumped heat energy storage system will provide to grid operators, including synchronous inertia, reactive power, and fast ramping.
