Keep Energy Systems

Keep Energy Systems Limited is a UK-based private limited company that specializes in distributed, long-duration energy storage solutions. Incorporated on April 25, 2025, the company focuses on addressing challenges in the global energy transition, such as grid connection delays and intermittent renewable generation. Formerly known as Cheesecake Energy, it rebranded to reflect its commitment to resilience and reliability in clean energy.

The company's flagship product, the eTanker, is an innovative energy storage system that combines thermal energy storage and compressed air. This technology offers medium- to long-duration storage at costs significantly lower than traditional batteries. By repurposing components from existing supply chains, Keep Energy Systems enables faster deployment of sustainable power solutions, supporting industrial decarbonization and local grid resilience.

In addition to its product offerings, Keep Energy Systems provides engineering-related scientific and technical consulting activities. The company is currently launching a £10M Series A funding round to scale its operations and meet the growing demand for reliable energy solutions.
