MOSS (Molten Salt Storage)

2024: Storage Launch

At the end of April 2024, the Danish company Hyme Energy launched the world's first clean energy storage platform using molten salts. The project was named Molten Salt Storage, or MOSS.

It is noted that the key problem when using "green" power plants is the preservation of excess energy generated on sunny or windy days for subsequent use. The MOSS platform provides that during periods of peak renewable energy generation, its surplus is used to heat the hydroxide salt, which in this case changes to a molten state. Such a salt, having an extremely high temperature, is able to store a huge amount of energy.

Hyme Energy compares the MOSS system to a giant ultra-efficient battery. When the generation of energy from renewable sources falls for some reason, such as on cloudy days or in windless weather, the heat stored in the molten salt is released, and this thermal energy can be efficiently converted into steam. Further, electricity can be generated for supply to the grid.

The molten hydroxide salt is said to be extremely heat resistant. Thanks to this, huge energy reserves can be stored with minimal losses. MOSS technology has the potential to decarbonize many energy-intensive industries. Heat consumption accounts for 50% of the world's total energy expenditure, with it accounting for 40% of carbon dioxide emissions. Future MOSS commercial facilities will be able to store "green" electricity in molten hydroxide salt heated to 700 degrees Celsius on a gigawatt-hour scale. The first storage of energy of a new type was opened in Esbjerg (Denmark).^[1]
