We have already discussed in this blog the need to find ways to store energy, in order to alleviate the problem of renewable energy and its "intermittency".
Until now most of the solutions to this problem proposed and carried out, are based on the use of electric batteries combining all kinds of materials.
But batteries are not only complex to design and manufacture but also continue to pose a problem when recycling after their useful life.

That is why the new Fluorine Liquid Salt Energy Storage Project, driven mainly by DTU Mechanics and Seaborg Technologie, has been launched.
With a high energy density, a low melting point and a high boiling point, we can heat the salt to approximately 700 degrees without evaporating it using renewable energy.
The stored energy from the salt is then used to operate a steam turbine that can generate new, green energy and heat in district heating.

According to John Hald, a member of the DTU Mechanics research group, the energy generated from renewable sources can be stored for several weeks.
The biggest problem currently is how highly corrosive these salts are, so part of the innovation project is to find materials that can retain the hot salt without rusting.
Once this is rectified, it will begin its large-scale installation and commercialization.
