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.

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.

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 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.

What is the Malta LDEs plant?

The Malta LDES plant stores electricity for days to weeks and converts variable renewables into reliable, on-demand power. It produces zero-emissions heat to decarbonize the hardest-to-tackle sectors of our economy: industrial, agricultural, buildings, and others.
