Denmark Leads the Way in Green Energy Storage with Hyme Energy’s Revolutionary Molten Salt Battery

In Denmark, Hyme Energy has launched the world’s first energy storage project using molten hydroxide salt to store green energy. The project, called Molten Salt Storage (MOSS), is a giant and extremely efficient battery that could revolutionize the way we store renewable energy.

The first MOSS facility is located in Esbjerg and was inaugurated by Soren Gade, President of the Danish Parliament. The solution to storing excess energy from renewable sources such as wind and solar is to heat the salt hydroxide, causing it to enter a molten state. Molten salt is kept at extremely high temperatures, allowing huge levels of energy to be stored with minimal loss.

This technology has the potential to decarbonize energy-intensive industries that rely on traditional fossil fuels for heat production. Heat consumption accounts for 50% of total energy consumption globally and also contributes 40% of carbon emissions. By providing a green alternative to traditional energy sources used for heat generation, MOSS aligns with Denmark’s and the world’s carbon reduction goals.

Following successful testing of the new facility, Hyme Energy plans to scale this technology for commercialization in 2026. Future commercial MOSS facilities could store green electricity in molten hydroxide salt heated to 700 degrees Celsius at the gigawatt hour (GWh) scale. This would allow us to store even more energy efficiently and effectively convert it into steam when needed.
