Who is Malta energy storage?

Malta is a long-duration energy storage company that builds grid-scale energy storage solutions to convert variable renewable energy into on-demand, around-the-clock, reliable power.

What is Google's 'Malta' energy storage project?

Malta spun out from the special projects group at Google’s parent company Alphabet and relies on some very old technologies combined in a novel way to provide long-duration energy storage that can be discharged during times of peaking demand — like the conditions that effected Texas’ power grid last week.

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).

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.
