4 FAQs about Solar heat storage salt

What is molten salt energy storage?

Solar power, which is one of the most abundant and sustainable energy sources, has attracted a lot of attention for its clean and renewable attributes amid a growing global demand for renewable energy. Molten salt (MS) energy storage technology is an innovative and effective method of thermal energy storage.

Should molten salts be used in thermal energy storage?

These salts are typically low cost, have a large energy storage density, are easily sourced/abundant and their use has a low environmental impact. Implementing molten salts as part of a thermal energy storage system, however, comes with some unique challenges.

What is molten salt storage in concentrating solar power plants?

At the end of 2019 the worldwide power generation capacity from molten salt storage in concentrating solar power (CSP) plants was 21 GWhel. This article gives an overview of molten salt storage in CSP and new potential fields for decarbonization such as industrial processes, conventional power plants and electrical energy storage.

How is thermal energy stored in a salt tank?

For sensible salts, thermal energy is stored by heating the salt and storing it in a “hot tank”. Thermal energy is extracted from the hot salt and used to run the power block when it is most valuable for grid demand. Once the energy has been extracted, the cooled salt is then stored in the “cold tank”.
