Transforming Industry. Strengthening the Grid.
The Thermal Battery Alliance is a first-of-its-kind coalition of clean technology companies dedicated to transforming the industrial and power sectors, strengthening U.S. manufacturing, and enhancing grid reliability while lowering energy costs for all.
OUR MISSION
The Thermal Battery Alliance is committed to spotlighting how American innovation can unlock a competitive and clean domestic manufacturing sector, create well-paying jobs, and reduce costs for U.S. energy consumers. Through state and federal policy advocacy and strategic partnerships across industries, the Thermal Battery Alliance aims to accelerate the deployment of thermal battery solutions that are cost-effective, rapidly scalable, and essential for the energy transition in the U.S. and beyond.

What is a Thermal Battery?
Intermittent electricity → Stored as high temperature heat → Delivered as reliable heat & power
Key Benefits
For Industry
Lower Costs: Electricity provides a low-cost pathway compared to alternative sources of generating heat.
High Temperature Heat: Thermal batteries deliver the high temperature heat demanded by heavy industrial sectors.
Domestic Manufacturing and Jobs: Our industry supports a clean, secure, and competitive U.S. manufacturing base and job growth in the industrial and energy sectors.
For the Grid
Flexibility & Reliability: Thermal batteries reduce curtailment of existing renewable electricity assets and provide on-demand energy when renewables are not available.
Reduced Congestion: Thermal batteries alleviate grid constraints by storing energy during periods of low demand and making it available when it’s most needed.
Improved Resilience: Thermal batteries reduce reliance on centralized power plants and enable localized energy solutions.
Key Facts
The market potential for thermal batteries in the industrial heat and grid sectors is massive.
By 2040, experts expect up to $3 trillion will be invested in long-duration grid storage systems that will be able to store and provide as much as 2.5 terawatts (TW) of power worldwide.
Existing thermal battery technologies store energy at temperatures high enough to address 99% of U.S. industrial heat demand using clean, surplus power.
The thermal battery industry is projected to create and retain tens of thousands of U.S. jobs, including in the manufacturing of thermal batteries, domestic battery supply chains, and across the broader U.S. manufacturing sector.
