EKFB, part of the construction joint venture working on the HS2 high-speed railway project in England, has embraced green hydrogen technology by deploying GeoPura's Hydrogen Power Units (HPUs) on two construction sites in Aylesbury. The decision follows a successful trial demonstrating the efficiency of hydrogen in reducing diesel usage and emissions. These HPUs, equipped with fuel cell technology, convert hydrogen gas into electricity while emitting only water vapor as a by-product. By replacing traditional diesel generators, the HPUs have significantly lowered carbon emissions and air pollutants, contributing to improved air quality at the sites. In line with HS2's goal of achieving net zero by 2035, EKFB aims to eliminate diesel use on all sites by 2029. The deployment of HPUs has already resulted in substantial environmental benefits, saving over 189 tonnes of CO2 equivalent and reducing NOx, CO, and particulate matter emissions. The positive outcomes have prompted EKFB and HS2 to further explore the potential of hydrogen technology in construction, highlighting the shift towards sustainable and environmentally friendly practices in the industry.
