SaltX energy storage density and corrosivity  


Hi SaltX,

Please could you tell what the energy storage density and corrosivity level (pH) of your salt mixture would be, if I was going to use the salt for domestic space heating applications-temperature range between 70-95Degrees C?




Hi Petar! Great questions! Our team of engineers did a precise pH measurement for salts that need about 80 degrees temperature difference to charge. The pH is slightly on the acid side - around 6.1. However, keep in mind that if you use SaltX technology it usually comes in a low pressure enclosed container.

The energy density of our salts ranges from 70 to 200 kWh/m3. The salt you would probably use in your system has around 160 kWh/m3 density.
