Boston – September 18, 2026 -- Electrified Thermal Solutions has signed an agreement with Holcim to deploy its Joule HiveTM Thermal Battery (JHTB) as part of the cement producer's electrification roadmap, marking a rare entry of electric heat into a process that has relied almost exclusively on combustion.
Two JHTB units will supply heat up to 1,800°C to a high-temperature cement process
The initial deployment consists of two Joule Hive units storing clean electricity in electrically and thermally conductive bricks, discharging heat on demand at temperatures up to 1,800°C (3,275°F). That range has been largely inaccessible to conventional electric heating technologies, forcing cement, steel and chemicals producers to depend on fossil combustion for their hottest processes.
Holcim becomes Electrified Thermal's third global industrial partner
The agreement extends an existing relationship in which Holcim is also an investor in Electrified Thermal. Industrial heat represents roughly one-fifth of global energy consumption, and the highest-temperature segment of that demand has remained largely closed to electrification until now, according to the companies.
Ram Muthu, Head of Operational Excellence at Holcim, said electrifying high-temperature industrial heat is among the advanced technologies the company is incorporating into its decarbonization strategy, and the deployment will allow Holcim to evaluate its potential.
Deployment follows 1,000+ hours of commercial demonstration in Texas
The move builds on Electrified Thermal's commercial demonstration system in San Antonio, Texas, which came online earlier this year as the company's first operational megawatt-scale system and has logged more than 1,000 hours of operation. Daniel Stack, CEO and co-founder of Electrified Thermal, said the Holcim deployment shows global industrial producers are ready to move the technology from demonstration to commercial-scale use.
Both companies said they are evaluating additional opportunities to apply the technology across Holcim's broader operations.
