Battery and flywheel energy storage manufacturer

Battery and flywheel energy storage manufacturer

At Dumarey Green Power, we are leading battery energy storage system manufacturers and flywheel energy storage manufacturers, specialising in advanced solutions that improve efficiency and sustainability across industries. Our portfolio includes state-of-the-art battery energy storage systems and flywheel energy storage systems, engineered to optimise energy use, reduce operational costs, and lower carbon footprints.

Energy stored, power delivered, savings made

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Dumarey revolutionises these outdated power systems with advanced solutions that reduce power supply requirements, cut costs, and lower the CO2 footprint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

Industrial high-power battery energy storage system manufacturer

The Revolution Battery is a high-power industrial battery energy storage system designed for seamless integration with generators, other batteries, or mains connections. Compatible with 16, 32, or 63 A mains supplies, it can power large dynamic equipment such as cranes, reducing or eliminating the need for generators.

Key benefits include:
– Lower fuel consumption with smaller, more efficient generators
– Smooth operation of heavy-duty equipment
– Reduced emissions and operational cost savings

The Revolution Battery is particularly effective in construction, mining, and off-road applications with frequent start-stop cycles and high peak power demands.
