Clean, co-generated steam is used for district heating or industrial use. Malta's electro-thermal energy storage system is composed using components with a long and proven record in the field. Molten salt is the most mature technology used in thermal storage.
The Malta PHES energy storage system is built upon well-established principles in thermodynamics and uses conventional components that have been present in power plants for hundreds of years. Electricity from the grid is used to heat molten salt and cool a chilled liquid. In these forms, energy can be efficiently stored for long durations.
Malta's electro-thermal energy storage system is built upon well-established principles in thermodynamics. When charging (taking electricity from the grid) the system converts electricity to heat, in molten salt, and as cold in a chilled liquid. In these forms, this energy can be efficiently stored for long durations.
Malta’s utility scale and inertial component make it uniquely suited for power companies with a focus on resiliency ready to move to long duration today. When coupled with renewables, Malta’s thermo-electric energy storage system enables the delivery of 24/7 green energy. Stores energy from any power generation source
Malta’s innovative thermo-electric energy storage system represents a flexible, low-cost, and expandable utility-scale solution for storing energy over long durations at high efficiency. The system is comprised of conventional components and abundant raw materials – steel, air, salt, and commodity liquids.
Malta uses commodity antifreeze to store liquid at below-freezing temperatures. Antifreeze solutions are commonly used as heat transfer fluids, making them some of the best-understood liquids in the energy sector. All materials and components used in Malta’s system are fully recyclable and can be reclaimed after use.
