Malta factory photovoltaic energy storage

What is Malta's energy storage system?

Q: Malta’s solution lies in thermo-electric energy storage. Why is this system so innovative, and what are its main keys? A: It combines well-established thermodynamic principles with modern technological advancements to create a cost-effective, scalable, and efficient energy storage solution.

What is the Malta PHES energy storage system?

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.

How is electricity stored in Malta?

Malta is built on research conducted by a Nobel Prize-winning physics professor, who came up with a theoretical system that stores electricity as heat in high temperature molten salt and cold in a low temperature liquid similar to the antifreeze in cars. The energy stored in the system can be kept for days or even weeks, until it’s needed.

Does Malta have a long-duration energy storage solution?

Malta has developed a long-duration energy storage solution that leverages steam-based heat pump technology to provide a cost-efficient, flexible, and integration-ready option for utility and industrial clients.

What materials are used in a Malta energy storage system?

Common metals and alloys, like steel and aluminum, make up the bulk of the piping, turbines, and other mechanical equipment used in a Malta energy storage system. Its durability, abundance, and recyclability make it a reliable choice for ensuring long-term system integrity while aligning with sustainable construction practices.

How efficient is Malta's thermal storage system?

Malta’s system also achieves a power-to-power charge/discharge round-trip efficiency (RTE) of up to 60%, which is about 50% higher than other thermal storage systems without heat pump charging.
