Kier is currently implementing a unique approach to power supply at the Bridgwater tidal barrier scheme in Somerset by using solar power along with a hydrogen fuel cell backup on an off-grid construction site. The trial, which started in January and will run for a year, has already shown promising results in terms of energy efficiency and environmental impact. By combining solar panels, green hydrogen, and batteries, the site has managed to save approximately 20,000 liters of diesel and avoid 53,000 kg of CO2e in just four months. This innovative technology not only aims to provide a continuous clean power supply but also supports the site's zero-emission goal. The project is a collaborative effort between Kier, TCP Group, and the Environment Agency, with the latter emphasizing the importance of green hydrogen in transitioning towards a sustainable future. Learnings from the trial have already led to improvements in energy usage monitoring and the addition of more fuel cells to enhance performance. The successful implementation of this hybrid hydrogen solution demonstrates a significant step towards achieving net zero goals in the construction industry.
