Case Studies

Dumarey supported customer to integrate third party Fuel Cell in their final application by studing a containerized solution.

Dumarey supplied the customers with custom controller and firmware to assist in integrating their application software for the next-generation fuel cell.

Fuel cell OEMs operating in the bus and truck sector needed a reliable and customizable control solution capable of managing the unique requirements of heavy‑duty fuel cell systems, including power distribution, thermal management, and real‑time diagnostics.

Dumarey deployed a Peak Power 200 flywheel system on a hybrid jaw crusher to enable generator downsizing and load levelling, reducing fuel consumption, emissions, and equipment stress.

Dumarey deployed a Peak Power 200 flywheel system on a tower crane to enable significant generator downsizing, reducing fuel consumption, operating costs, and emissions.

Dumarey supplied Locquet Power and Light together with Power Solutions a flywheel system which allowed them to downsize on generators significantly.

Dumarey supplied IZON a Power Factor Correction System. The systems improve the power factor on the electricity produced by the wind turbines. The battery removed the requirement for a diesel generator which cut costs and emissions.

Dumarey deployed a Peak Power 200 flywheel system alongside an industrial shredder to enable generator downsizing, reducing fuel consumption, costs, and emissions.

Dumarey Green Power supplied London Tower Cranes a Revolution Battery to run a tower crane. The battery removed the requirement for a diesel generator which cut costs and emissions.

The Peak Power 200 flywheel allowed a diesel generator powering a remote underwater vehicle to be downsized, resulting in fuel, cost and emissions savings.

The Peak Power 200 flywheel enabled a WOLFF tower crane at Dubai Harbour to run on a downsized 200kVA generator instead of a 500kVA diesel unit – delivering significant fuel and emissions savings even in extreme heat conditions where battery systems struggle.

The Peak Power 200 flywheel enabled a diesel generator powering an industrial chiller be downsized, resulting in fuel, cost and emissions savings.

Dumarey Green Power supplied a Revolution Battery to Brogan Group for trialling on a construction hoist. The battery captured regenerative energy and eliminated the need for a diesel generator, cutting costs and emissions.

Dumarey Revolution Battery is used to power two tower cranes simultaneously, removing a diesel generator from site and saving 2 tonnes of CO₂ per week.

Dumarey Green Power supplied a major UK contractor a hybrid power solution combining a PowerSkid second-life battery energy storage system and a Peak Power 200 flywheel system to power five Terex CTL-630 luffing jib cranes.

Dumarey Green Power deployed a single Revolution Battery to power two tower cranes on an HG Construction site in London, replacing two diesel generators and achieving a 94% reduction in CO₂ emissions.

A high-cycle flywheel energy storage system designed to stabilise cyclic loads, optimise generator performance, and reduce fuel consumption and emissions in demanding industrial environments.

Dumarey Green Power deployed a PowerSkid battery energy storage system (BESS) at a German industrial bakery to reduce peak electricity demand. The system performs peak shaving and stores solar energy, enabling the bakery to operate within a limited grid connection while lowering electricity costs and CO₂ emissions.

Dumarey Green Power supplied London Tower Cranes a Revolution Battery to run a tower crane. The battery removed the requirement for a diesel generator which cut costs and emissions.
