How Hyme storage works

Charging

Electricity from renewables is converted into heat through electrical heaters. Salt from the cold tank is circulated through the heaters and heated up from 350 ºC to 700 ºC, then stored in the hot tank for up to several days.

Discharging

The energy stored in the hot tank is released on-demand by circulating the hot salt to a heat exchanger where the heat is transferred to water and turned into high temperature steam. Steam can be used directly in an industrial process or used to power a turbine and deliver electricity and heat. The cooled salt is pumped back into the cold tank until the next charging cycle.
