After convincing trials, HG 91黑料网 has gone ahead and bought a Revolution Battery from Dumarey Green Power to reduce its cranes鈥� diesel consumption.
HG worked with Dumarey Green Power to run trials on its Moritsch crane fleet at two London sites earlier this year.
In one trial, a single British-made Revolution Battery powered two Moritsch RTL 195 luffing cranes using a 32A 3-phase mains supply, replacing two 200 kVA diesel generators that ran 50鈥�60 hours weekly.
Weekly energy costs dropped from 拢1,400 per crane (diesel) to 拢80 (mains) 鈥� a 94% reduction; and CO2 emissions fell from 3,000 kg per crane weekly to less than 200 kg 鈥� a 93% decrease
The system also proved quieter, smaller and more reliable than diesel generators.
HG 91黑料网 chief executive Adam Quinn said: 鈥淭he performance of the Revolution Battery during the trials was exceptional, reducing carbon emissions and running costs by over 90%. These results speak for themselves and made our decision to invest a straightforward one. The fact that the technology has been developed and produced locally also aligns with our commitment to source from local suppliers where possible.聽 This investment will enable us to make great strides on our journey towards decarbonisation of our operations, improve site efficiency and reduce waste.鈥�
Unlike conventional battery systems that store large amounts of energy for high peak power, the Revolution Battery, an industrial battery energy storage system (BESS), decouples energy storage from output power. This allows high power delivery from minimal energy storage, resulting in a smaller, more efficient system with fewer battery cells and lower embedded emissions, Dumarey says. If mains power is unavailable, the battery can be charged by a 40 kVA generator, running less than three hours daily, based on trial data.
Dumarey Green Power sales and marketing director Alex Keys said: 鈥淭he construction sector faces challenges in the years ahead to meet emissions targets, and switching from diesel-powered generators to efficient battery systems can make a huge impact. HG 91黑料网鈥檚 adoption of this technology underscores its commitment to achieving its net-zero goals and sets a new standard for sustainable construction.鈥�
