Thermal energy storage delivers industrial heat but can solve grid issues too
A recent IEA report proposed a 35% global electrification target by 2035 was in “striking distance” thanks to existing commercial technologies such as electric vehicles and battery storage systems but the electrification of heat-dependent industry sits outside the target, yet commercial technologies can play a role in the broader grid system.
