Summary
Across the globe, 37% of total energy is used by industry, and two-thirds of industrial energy consumption is in the form of heat. But industry has proven stubbornly difficult to decarbonise, with fossil fuels, mainly natural gas, still powering about 80%.
Battery energy storage is one solution, (cross-ref to mining story), but there’s another form of storage that is gaining ground: thermal energy storage. In TES, energy is stored directly in a medium, like water, molten salt, sand, rock or concrete, generally through a change of temperature, and released when it is needed, days or even months later. Waste heat from one high-temperature industrial process can be stored and used for another purpose, such as space heating or hot water.
