Thaleron

Thaleron develops undersea flywheel energy storage technology, offering mechanical storage at a fraction of traditional flywheel material costs with over 92% efficiency.

Thaleron, founded in 2022, is a cleantech company developing a novel mechanical energy storage system based on patented undersea flywheel technology. The company's approach targets a fundamental cost barrier in energy storage: its design stores the same energy per kilogram as conventional flywheels but at approximately 1/200th the material cost, with efficiency exceeding 92%.

The technology positions Thaleron within the broader effort to enable wider adoption of renewable energy by addressing grid-scale storage economics. The company operates from Maidenhead and Woking, Surrey, in the United Kingdom.

Thaleron's technical domains span cleantech, energy storage, mechanical engineering, and flywheel technology. The company states it is backed by significant financial support and is pursuing what it describes as a critical mission in the energy transition.
