New thermal battery and solar tech help mining companies get rid of diesel
247Solar launches HeatStorE™, a long duration thermal battery made for adding more renewables to remote mining operations, industrial and grid solutions than is feasible with conventional batteries
Great Falls, VA, USA, June 24th, 2021 – A robust new battery from 247Solar Inc., a spinoff of MIT, operates almost like an electrochemical battery but has significant advantages at longer durations. The basic principle of the thermal battery is rather simple. Electric resistance coils heat an inexpensive thermal storage medium (silica sand) using low-cost excess electricity, e.g., from intermittent solar and wind power sources. Energy is stored as ultra-high temperature heat (up to 1000℃/1850℉) – at a fraction of the cost of batteries. Whenever needed, a specialized turbine reconverts the heat t...
