EarthEn Energy, a climate-tech leader in long-duration energy storage (LDES), proudly unveiled its EarthEn Heat Battery at RE+ Storage in Santa Clara. This innovative solution uses renewable energy to decarbonize high-temperature industrial heat processes while boosting energy resilience and increasing overall industrial efficiency.
As a participant in Oak Ridge National Laboratory’s (ORNL) Lab-Embedded Entrepreneurship Program (LEEP) at the Innovation Crossroads project, EarthEn is using top-notch R&D capabilities to hasten the commercialization of its storage solutions.
This innovative technology, which was developed with assistance from the National Science Foundation (NSF), Launch Tennessee (LaunchTN), Partnership for Economic Innovation (Arizona), the U.S. Department of Energy (DOE), and the California Sustainable Energy Entrepreneur Development Initiative (CalSEED), has the potential to transform the way that industries produce and store thermal energy by offering a resilient, affordable, and dispatchable heat source.
Industrial Heat Storage Revolution
With a scalable modular design appropriate for industrial-scale deployments, up to 90% round-trip efficiency, and adjustable 4–12 hour storage durations, the EarthEn Heat Battery stores excess renewable electricity and releases it as high-temperature steam or hot air (200°C to 500°C) on demand. All of these features come at a competitive price.
Furthermore, the Heat Battery captures and repurposes waste heat from industrial operations, storing and rerouting it back into production cycles. By lowering fuel consumption, increasing total thermal efficiency, and reducing energy losses, this helps enterprises improve their operations while reducing expenses and emissions.
Importantly, the Heat Battery also offers energy resiliency, guaranteeing that businesses have consistent access to heat even in the event of outages, grid fluctuations, or dips in renewable power, assisting in the maintenance of supply chain stability and continuous operations.
“Industrial heat is one of the toughest sectors to decarbonize,” stated Dr. Manas Pathak, CEO & Founder of EarthEn Energy. “Our Heat Battery gives manufacturers a practical, reliable, and affordable way to utilize clean energy, recover waste heat, and keep their operations resilient and efficient 24/7 on clean energy.”
Dr. Palash Panja, CTO and co-founder of EarthEn Energy, added, “We’ve engineered the Heat Battery to integrate seamlessly into existing systems, making it a plug-and-play solution for industries looking to cut emissions, reuse heat, boost reliability, and stay cost-competitive.”
Industrial Applications
The EarthEn Heat Battery is designed for multiple energy-intensive sectors, including:
- Food & Beverage Processing (drying, boiling, sterilization)
- Textile & Dyeing industries
- Pulp & Paper manufacturing
- Pharmaceuticals and chemical processing
- Petrochemical and other high-temperature applications
With containerized or skid-mounted options, the system minimizes installation time and cost, making clean heat deployment fast and efficient.
The launch event featured a product demonstration of the Heat Battery and highlighted upcoming pilot projects planned for 2025.
