EKFB, a joint venture of Eiffage, Kier, Ferrovial Construction, and BAM Nuttal, has extended its GeoPura agreement. The agreement involves deploying green hydrogen-powered generators (HPUs) at two HS2 construction sites in Aylesbury, UK. The decision follows a successful initial trial and aims to reduce NOx, CO2, and particulate matter emissions. This will be achieved by replacing diesel generators for the entire project duration.
EKFB’s Role in HS2 Phase 1
EKFB has secured a contract to deliver 80km of the High Speed Two (HS2) Phase 1 route. The route runs between the Chilterns and south Warwickshire. The joint venture commits to driving the adoption of alternative fuel innovations. This commitment aims to meet its diesel-free ambition by 2029.
GeoPura’s HPUs: A Clean Power Solution
GeoPura’s HPUs offer several advantages as a clean power solution for construction sites:
- Strategic placement: The HPUs are located at the ‘Footpath SMA9 Accommodation Overbridge Compound’ and ‘Thame Valley Viaduct’ sites. Grid connections are not feasible at these locations.
- Fuel cell technology: The generators use fuel cell technology to convert hydrogen gas into electricity. This process emits only water vapour.
- Emissions reduction: The systems have already saved over 189 tonnes of CO2 equivalent, contributing to sustainability goals.
- Reliability: GeoPura’s HPUs have proven to be an excellent and reliable source of zero-emissions power from the outset.
Industry Reactions
Andrea Davidson, HS2 Head of Carbon and Climate Change, praised EKFB’s efforts. She stated, “This is an excellent example of how EKFB, through HS2 construction, is driving alternative fuel innovation adoption. This helps meet our diesel-free ambition by 2029.”
GeoPura CEO Andrew Cunningham highlighted the significance of the contract extension. He said, “The extension of our contract underlines how clean power can become ‘business as usual.’ Historically, the industry has proactively removed many health threats from their working environment. GeoPura is delighted to help EKFB and HS2 eliminate diesel use on all their sites. This leaves a sustainable legacy for one of the UK’s most significant infrastructure projects.”
Alan Silverster, EKFB’s Carbon Manager, commended GeoPura’s HPUs. He noted that they have been “an excellent and reliable source of zero emissions power from the outset.”
The Future of Clean Power in Construction
The extension of the EKFB and GeoPura agreement showcases the growing importance of clean power solutions in construction. More companies are striving to reduce their environmental impact and meet sustainability goals. As a result, the adoption of green hydrogen-powered generators and other alternative fuel technologies is likely to increase. This sets a new standard for eco-friendly construction practices.
