World patented nano-technology


SaltX uses nano-coated salt to store energy thermo-chemically. The patented technology is all-natural, very scalable and prevents corrosion. The salt has a good volumetric energy density and the nano-coating enables a long life to/for a low-cost material.

Thermo-chemical energy storage 


The energy is stored chemically, by separating salt from water, and then released by combining them again. The technology allows thermal energy to be stored and used hours, days, or months later. At scales ranging from individual processes to large scale storage for municipalities and cities. SaltX Thermo chemical energy storage can be charged with both electricity and heat and then be released as heat up to 500°C (930°F).

A closer look at sustainable energy


The SaltX nano-coating prevents the salt from becoming sticky, making the salt retain its original single crystal form. The advantage of this is that you can charge and discharge energy thousands of times without losing performance. Regular salt particles begin to grow bigger after only 50 charges.

When the salt is treated with nano-coating it also has the advantage of being non-corrosive (preventing rust) unlike ordinary salt. It provides a long-term and cost-effective solution. SaltX is non-toxic and can be recycled.

How it works


SaltX is storing energy chemically with salt. Through separating salt and water molecules from each other you charge the “thermal battery”.

  1. When the nano-coated salt is uncharged it is a mixture of salt and water.
  2. When charging the salt you heat it up to 500 degrees Celsius. The water evaporates from the water and the dry salt is now charged.
  3. As long as the salt is dry you can keep the salt charged. The salt can be stored at normal room temperatures.
  4. When discharging the energy you add steam or water to the salt and a chemical reaction releases 500 degrees Celsius.
