2026 R&D Manufacturing Co-Op

About Electrified Thermal Solutions

Boilers, furnaces, and kilns are the engines of our industrial economy, providing heat to melt steel, form cement, and transform chemicals. But historically reaching this high-temperature heat required burning fossil fuels, making the industrial sector responsible for 25% of global greenhouse gas emissions. 

Electrified Thermal Solutions has a simple and massive goal: to electrify industry.  

To do this, we are building the Joule Hive™ thermal battery: an energy storage technology that converts and stores cheap, renewable electricity as high-temperature heat. Our vision is to mitigate gigatons of CO2 emissions per year by deploying the Joule Hive™ at every industrial furnace, turbine, boiler, and kiln.
