A trial conducted by Kier and the Environment Agency in Somerset, specifically at the Bridgwater Tidal Barrier scheme, is showcasing the potential of using solar power with green hydrogen backup as a primary power supply on a construction site lacking access to mains electricity. Over the first four months, the trial has demonstrated impressive results, with significant energy savings and carbon emission reductions when compared to traditional diesel generators. By combining solar panels, hydrogen fuel cells, and batteries, the system provides a continuous, zero-emission power supply, contributing to a sustainable future. The technology not only reduces carbon emissions but also diminishes noise levels on-site and avoids spill risks associated with generators. Key figures involved in the project, such as Jo Driffield from the Environment Agency and Hannah McIlroy from Kier, highlight the importance of such trials in realizing net zero goals and promoting sustainable energy solutions. Furthermore, the collaboration with TCP Group has allowed for valuable learnings and improvements in energy conservation practices. The successful implementation of this innovative hybrid hydrogen solution signifies a significant step towards shaping energy practices based on data monitoring and encouraging behavioral change.
