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.

What is Malta's energy storage system?

Malta’s grid-scale, long-duration energy storage system helps governments, utilities, and grid operators transition to low-cost, carbon free renewable energy while enhancing energy security. Storing electricity for eight hours to eight days or longer, the solution reduces CO 2 emissions and dependence on natural gas.

Is Malta a ready-to-market energy storage solution?

Today Malta is in advanced discussions with a more than a dozen utilities in Europe, and the Americas over plans to deploy Malta’s long duration energy storage technology. As the urgency of the energy transition grows, interest in Malta’s ready-to-market, thermo-electric energy storage solution has skyrocketed.

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.

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).
