Replacing fire with
ETS is developing the Joule Hive: a new energy storage technology that converts surplus zero-carbon electricity into heat. The stored heat can replace fossil fuels in industrial processes such as cement or iron production, or run a turbine for on-demand electricity at a fraction of the cost of lithium-ion batteries. The innovation of the Joule Hive stems from a novel joule-heating system, built from electrically conductive ceramics developed at MIT. With its unique ability to store gigawatt-hours of energy, hot as flames, the Joule Hive may act as a drop-in replacement for fossil fuels to decarbonize the energy consumption of any co-located industrial plant.
