Core offering

Electrified Thermal Solutions manufactures and sells the Joule Hive Thermal Battery, an industrial-scale thermal energy storage system that uses proprietary electrically conductive firebricks (E-Bricks) to convert off-peak electricity into high-temperature heat (up to 1,800°C) and deliver it on demand to furnaces, boilers, and kilns. The system is sold as modular capital equipment (1–200 MW scalable) to global heavy industrial enterprises—cement, steel, chemicals, mining, and glass—to replace fossil fuel-fired process heat with zero-carbon electric heat at costs below natural gas.

Product overview

Electrified Thermal Solutions offers a single unified product: the Joule Hive™ Thermal Battery, which uses proprietary electrically conductive E-Bricks as the core technology component. The system converts off-peak electricity into stored thermal energy at temperatures up to 1,800°C, delivering zero-carbon industrial heat on demand to replace fossil fuels in cement, steel, chemicals, glass, mining, and other energy-intensive industries. The Joule Hive integrates directly with existing industrial infrastructure and electrical grids, providing cost-competitive alternative to natural gas.

Products and services

• Joule Hive Thermal Battery A modular thermal energy storage system that converts off-peak electricity into high-temperature heat (up to 1,800°C) stored in electrically conductive firebricks, then delivers zero-carbon industrial heat on demand to furnaces, boilers, and kilns at temperatures competitive with natural gas. Scalable from 1 MW to 200 MW thermal output with >98% round-trip efficiency. Sold as capital equipment installations to global heavy industrial enterprises (cement, steel, chemicals, mining, glass) and adapted for utility grid storage applications.
• E-Bricks (Electrically Conductive Firebricks) Proprietary, patented (developed over 10+ years at MIT) electrically and thermally conductive 100% oxide-based firebricks that joule-heat to 1,800°C in ambient air without oxidation. Serve simultaneously as heating element, thermal storage medium, and heat exchanger in the Joule Hive Thermal Battery with projected 20-30 year lifespan. Manufactured by HWI/Calderys under strategic partnership and in-house at the Boston production facility.
