6 FAQs about [Causes of heating in energy storage system]
Why is heat storage important?
For industrial processes that have time varying heat demands, are batch processes or produce waste heat, heat storage can be used to reduce peak loads, shift heat availability in time and allow waste heat to be better utilised.
