Denmark has just launched its first molten salt green energy storage facility, which is a giant and extremely efficient battery. Danish company Hyme Energy has created the world’s first energy storage project using molten hydroxide salt to store green energy. The project is called Molten Salt Storage (MOSS) and the first facility is located in Esbjerg. The facility was inaugurated by Soren Gade, President of the Danish Parliament, on April 26.
The challenge with using green energy is storing the excess energy produced during sunny or windy days for later use. Hyme Energy’s solution is to store excess electricity in molten hydroxide salt. MOSS works like a giant battery and is highly efficient. The new facility will store energy from renewable sources such as wind and solar. During periods of good production, excess electricity is used to heat the salt hydroxide, causing it to enter a molten state. Molten salt is kept at extremely high temperatures, helping to store enormous levels of energy.
In the future, commercial MOSS facilities could store green electricity in molten hydroxide salt heated to 700 degrees Celsius at the gigawatt hour (GWh) scale, according to Ask Emil Lovschall-Jensen, CEO and co-founder of Hyme Energy. By storing green electricity in molten hydroxide salt, MOSS creates a sustainable and reliable reserve when renewable electricity production is low. Then, the heat energy stored in the molten salt is released and effectively converted into steam.
Molten hydroxide salts withstand heat very well, allowing huge levels of energy to be stored with minimal loss. This stored energy can be used as a viable alternative to traditional fossil fuels used in power plants and even heavy industries. MOSS has the potential to decarbonize energy-intensive industries such as heating systems that account for 50% of total global energy consumption and also contribute 40% of carbon emissions. By providing a green alternative to traditional sources used for heating purposes, MOSS aligns with Denmark’s and the world’s carbon reduction goals.
The newly opened storage facility will undergo rigorous testing before it can be scaled up for commercialization in 2026.
In conclusion, Hyme Energy’s innovative solution provides an efficient way to store excess green energy produced during sunny or windy days for later use through their new Molten Salt Storage (MOSS) project launched in Denmark earlier this year. This technology has immense potential to transform how we generate and use heat globally while reducing carbon emissions aligned with our climate change goals.
