HG Construction Invests £1.2m in ‘Revolution Battery’
Leading UK contractor HG Construction is partnering with Dumarey Green Power to decarbonize its crane and hoist operations across the company’s UK sites.
HG Construction has made a £1.2m investment into Dumarey’s ‘Revolution Battery’ following a successful trial on two HG sites earlier this year. The investment will enable HG Construction to significantly reduce carbon emissions and operational costs on its sites, and is aligned with the company’s commitment to adopting more sustainable construction practices.
HG Construction partnered with Dumarey Green Power to run trials on its Moritsch crane fleet at two London sites earlier this year. In one trial, a single Revolution Battery powered two Moritsch RTL 195 luffing cranes using a 32A 3-phase mains supply, replacing two 200 kVA diesel generators that ran 50–60 hours weekly. The results were transformative:
- Cost Savings: Weekly energy costs dropped from £1,400 per crane (diesel) to £80 (mains) – a 94% reduction
- Emissions Reduction: CO2 emissions fell from 3,000 kg per crane weekly to under 200 kg – a 93% decrease
- Reliability and Efficiency: The system proved quieter, smaller and more reliable than diesel generators
Adam Quinn, CEO, HG Construction, commented: “The 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. This investment will enable us to make great strides on our journey towards decarbonisation of our operations, improve site efficiency and reduce waste. Looking forward, we remain committed to embracing innovations that deliver tangible environmental and operational benefits.”
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 innovation allows high power delivery from minimal energy storage, resulting in a smaller, more efficient system with fewer battery cells and lower embedded emissions. 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.
Alex Keys, Sales and Marketing Director, Dumarey Green Power, said: “We are delighted to be partnering with HG Construction as the business makes a bold step towards decarbonising its crane and hoist operations. The 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 Construction’s adoption of this technology underscores its commitment to achieving its net-zero goals and sets a new standard for sustainable construction.”
Manufactured in the UK by Dumarey Green Power, the Revolution Battery leverages local labour and suppliers, minimising transport emissions and supporting the UK construction market.
