MIT spinout Electrified Thermal Solutions has inked a deal with HWI, a member of Calderys and one of the biggest refractory suppliers in the US, to make electrically conductive firebricks – electric bricks, or E-bricks – that store and deliver extreme heat using renewable electricity.
The innovative partnership is all about scaling up Electrified Thermal’s Joule Hive Thermal Battery, which conducts clean power and stores it as heat up to a scorching 1,800C (3,275F). That’s hot enough to drive even the most energy-hungry industrial processes like steelmaking, glass, or cement production.
The E-bricks enable factories to ditch fossil fuels and run on renewables without sacrificing performance or reliability, and at a lower cost.
The MIT-developed tech is getting paired with HWI’s 160-year track record in high-heat materials. The E-bricks will be built in HWI’s existing US plants, which means the system can scale fast using current supply chains instead of building new factories from scratch.
Electrified Thermal expects its first commercial-scale Joule Hive system to come online this year. By 2030, the Boston-based startup wants to deploy 2 gigawatts’ worth of thermal power across industry.
“Industrial heat represents one of the most challenging frontiers in the world’s effort to address climate change,” said Daniel Stack, Electrified Thermal’s CEO and co-founder. “The majority of energy used for it worldwide still comes from burning fossil fuels. Our partnership with HWI transforms what could have been a manufacturing bottleneck into a powerful scaling advantage.”
HWI says Electrified Thermal’s E-brick is a breakthrough. “It maintains the high-temperature durability required by customers, while also generating the heat to run their processes,” said Ben Stanton, director of applications technology at HWI.
Calderys’ global VP of innovation, Bruno Touzo, added that the company is ready to help expand E-brick production across its global network. “It enables us to respond effectively to the growing demand from industries transitioning to cleaner energy solutions,” he said.
