Malta energy storage firefighting

How does energy storage work in Malta?

Malta’s innovative long-duration energy storage technology stores electricity as thermal energy from eight hours to eight days or longer, later returning it to the grid to meet hourly, daily, and weekly needs.

Is Malta the first company to commercialize a thermoelectric energy storage system?

Christian Bruch, President and CEO of Siemens Energy, said, “ Malta’s innovative thermoelectric energy storage system offers a flexible, cost-effective and scalable solution for the storage of energy over long periods of time. With our support, Malta is well positioned to be the first company to commercialize such a solution globally.

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.

Who invested in Malta energy?

CAMBRIDGE, Mass.-- ( BUSINESS WIRE )--Malta Inc., a leader in long-duration energy storage, today announced that it has closed on a round of financing provided by a group of investors including Siemens Energy Ventures and Alfa Laval as well as existing shareholders Breakthrough Energy Ventures, Proman, Chevron Technology Ventures, and Piva Capital.

How long can a Malta storage unit be charged and discharged?

A: A Malta storage unit can be charged and discharged 100% in unlimited cycles without degradation of the storage media. As the main storage medium, Malta has selected a natural thermo-solar salt sourced by solar evaporation (e.g., in the Atacama Desert of Chile).

How is the Malta plant built?

It is built using proven subsystems deployed around the world today, like heat exchangers, molten-salt and industrial-coolant storage, and turbomachinery. The base Malta plant can discharge 100-MW of clean energy for 10-to-200+ hours. Designed for flexibility, its charge and discharge speeds can be independently tailored to meet an owner’s needs.
