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.

Will Malta's new energy storage system revolutionize grid-scale energy storage?

Malta’s new energy storage solution has the potential to revolutionize the future of grid-scale energy storage. The system can draw electricity from the grid in times of plenty and store it for hours or days, waiting until a time of high demand before releasing the power back to the grid.

Why should you invest in Malta's new energy storage solution?

A vital part of Malta’s new energy storage solution is heat transfer technology supplied by Alfa Laval. As both an investor and a partner in the project, Alfa Laval lends more than expertise and financial backing.

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).

What are the advantages of a Malta cooling system?

The Malta system stands out for its cost effectiveness and environmental advantages. It relies on readily-available, low-cost materials like steel tanks, air, cooling liquids, and salt—a substance that is easily extracted from earth and capable of storing heat with minimal degradation or toxic byproducts.
