EKFB, a joint venture working on delivering 80 km of the HS2 Phase 1 route, has introduced green hydrogen-powered generators at two critical sites. The successful trial demonstrated a significant reduction in diesel usage and emissions, leading to the extension of hydrogen technology for the entire project duration. These generators, powered by advanced fuel cell technology, provide clean, efficient, and zero-emission electricity, contributing to a sustainable construction approach. The deployment has saved over 189 tons of CO2 equivalent and improved air quality by reducing NOx, CO, and particulate matter emissions. Key figures from EKFB and HS2 highlight the importance of transitioning away from diesel towards cleaner energy sources like hydrogen. The successful use of GeoPura HPUs showcases the viability and environmental benefits of hydrogen-fueled generators in the construction industry, setting a positive example for sustainable practices.
