Battery and Flywheel Energy Storage Manufacturer

Many of our customers operate equipment with dynamic duty cycles, requiring motors to stop and start frequently. This is inefficient and wastes energy.

Dumarey revolutionises these outdated power systems with advanced solutions that reduce power supply requirements, cut costs, and lower the CO₂ footprint

Our flywheel and battery energy storage systems capture, optimise, and reuse energy across a wide range of applications and industries.

Our roots: energy storage system manufacturers

We founded Flybrid Systems in 2007 to increase the efficiency of Formula One cars using flywheel energy storage technology.
We realised that the technology could positively impact society on a larger scale and adapted the flywheel technology to work across a broader range of industries. We now offer flywheel energy storage systems for medium/heavy-duty equipment, green energy, and automobiles.
In 2021, we launched our flagship product, the Peak Power 200 flywheel solution, which has already saved over 8 million litres of diesel.
In 2024, Dumarey Green Power acquired Time Shift, the leading innovator in battery energy storage systems built from second-life batteries.

As global flywheel energy storage suppliers and battery energy storage system suppliers, we deliver solutions to industries seeking high-performance, sustainable energy storage.
