Electrified Thermal Solutions, Inc. is developing the Joule Hive: a new energy storage technology that converts surplus zero-carbon electricity into heat
About Electrified Thermal Solutions
Electrified Thermal Solutions is a pioneering startup that is revolutionizing the industrial heating sector by electrifying firebricks. The company's innovative product, the Joule Hive thermal battery (JHTB), is a result of nearly a decade of research at MIT. The JHTB is a thermal energy storage system that uses electrically and thermally conductive bricks to provide low-cost, decarbonized heat for industrial applications. The system can reach temperatures up to 1,800°C (3,275°F), making it suitable for high-temperature industries such as steel, cement, glass, and chemicals.
The company's business model involves partnering with existing brick manufacturers to ensure scalability. The electrically conductive firebrick, the core of the JHTB, is a game-changer in the industry. It can convert electricity to high temperatures, enabling the electrification of high-temperature industries. Moreover, the high temperatures achieved by the bricks allow for energy storage with over 95% efficiency. This means that inexpensive off-peak electricity can be used to reduce the cost of decarbonization, making it competitive with existing fossil fuel sources.
The JHTB works by running electricity through the bricks to heat them up to 1,800°C. The thermal energy is stored at that temperature and then discharged by running air or another gas through the brick channels. This heat can then be used in any furnace, boiler, turbine, or kiln. This innovative approach to industrial heating positions Electrified Thermal Solutions as a leader in the decarbonization of the industrial sector.
