How Does eStor™ Work?
Compact Design
Flexibility
Our eStor thermal batteries are Compatibles with any heat or power source.
Grid Balancing 
Energy density and retention are key for supporting the national grid, enabling utility providers to shift loads and plan usage optimally. High-density energy storage allows for load shifting to off-peak times, reducing strain during peak demand. This enhances grid stability, promotes cost-effective distribution, and facilitates long-term planning for future demand fluctuations. In summary, energy density and retention are vital for grid efficiency and resilience.
Cost Effective 
eSTOR™'s exceptional energy density and retention assists the national grid and utility providers with a load shifting option for optimal time of use planning. Giving homeowners the ability to store thermal energy during off-peak hours saves money, supports a more stable grid, and maintains comfort.
