Kier has successfully conducted a trial of solar and green hydrogen energy at the Bridgwater Tidal Barrier scheme in Somerset, United Kingdom. Over a four-month period, the project saved approximately 20,000 litres of diesel by utilizing 16,047 kWh of energy, with a significant portion coming from solar power and green hydrogen. This initiative resulted in the reduction of approximately 53,000kg of carbon dioxide equivalent (CO2e) emissions compared to traditional diesel generators. The technology used at the site, which integrates solar panels, hydrogen fuel cells, and batteries, aims to provide a zero-emission and continuous renewable energy supply, reducing both carbon emissions and noise levels on site. The trial is part of a minimum 12-month experiment to assess the viability of utilizing solar power with green hydrogen backup in construction sites without access to mains electricity. Industry experts have praised the initiative for showcasing the potential of green hydrogen technology in reducing carbon footprints and noise pollution in construction. The trial also highlights the importance of such innovative projects in promoting sustainable energy solutions like green hydrogen across the construction industry.
