HS2 construction sites embrace hydrogen power.

Construction joint venture EKFB is revolutionizing sustainable construction practices by implementing green hydrogen-powered generators at two key HS2 sites.

After a successful trial period which showcased the effectiveness of hydrogen in reducing diesel usage and emissions on construction sites, EKFB has decided to extend the use of hydrogen technology for the entirety of the project’s duration.

Comprised of Eiffage, Kier, Ferrovial Construction, and BAM Nuttall, EKFB is tasked with delivering approximately 80 km of the HS2 Phase 1 route.

This transition is crucial as construction companies typically rely heavily on diesel generators when grid access is limited. However, GeoPura HPUs offer a sustainable alternative by harnessing the power of hydrogen to provide clean, efficient, and zero-emission electricity.

The hydrogen-powered generators have been strategically placed at the Footpath SMA9 Accommodation Overbridge Compound and the Thame Valley Viaduct sites. These locations, situated in rural areas, presented unique challenges that were successfully overcome to ensure consistent, clean, and reliable off-grid power supply.

With advanced fuel cell technology, the HPU converts hydrogen gas into electricity, emitting only water vapor as a by-product. This solution not only reduces carbon footprint but also enhances air quality and reduces noise pollution on construction sites.

Since their deployment up to June 2024, the HPUs have saved over 189 tons of CO2 equivalent – equivalent to the emissions from more than 2,500 passenger flights from London to Rome. Additionally, significant reductions in NOx, CO, and particulate matter emissions have greatly improved air quality at the construction sites.

Andrea Davidson, HS2 Head of Carbon & Climate Change, expressed her approval by stating, “This is an excellent example of how EKFB is spearheading the adoption of alternative fuel innovations to achieve our diesel-free goal by 2029 through the construction of HS2. The technology, free of harmful pollutants, provides substantial air quality benefits to both the workforce and local communities, a crucial aspect across the entire HS2 project.”

Backing this sentiment, Alan Silverster, EKFB Carbon Manager, emphasized, “Moving away from the use of diesel and other fossil fuels is a fundamental part of EKFB’s carbon strategy, and hydrogen serves as a vital component in offering versatile, clean energy to reduce the carbon footprint of construction operations. We are dedicated to showcasing the benefits of hydrogen in a live environment and believe in its potential to transform construction sites for the better.”

Andrew Cunningham, CEO of GeoPura, echoed similar sentiments, “The successful integration of GeoPura HPUs at EKFB’s sites showcases the practicality and environmental advantages of clean, hydrogen-fueled generators. Witnessing EKFB’s commitment to improving local air quality and reducing climate change impact has been truly inspiring. Our collaboration demonstrates how clean power can seamlessly blend into everyday construction operations, leaving a sustainable legacy for one of the UK’s most significant infrastructure projects.”

Their dedication to the environment and pioneering spirit towards green technology ensures that the partnership between EKFB and GeoPura continues to thrive, setting a shining example for the construction industry as a whole.

As EKFB and GeoPura work hand in hand, eliminating diesel use across all construction sites, they are paving the way for a brighter, cleaner, and more sustainable future for construction projects across the UK.
