Kier, a major construction company, is conducting a trial at the Bridgwater Tidal Barrier scheme in Somerset to explore the feasibility of using solar power with green hydrogen as a backup to power construction sites. The trial aims to reduce diesel consumption, carbon emissions, noise levels, and the risk of spills associated with traditional generators. The data from the trial will help determine if this approach can be scaled up for larger construction sites in the future. The consortium led by Bam is also testing dual-fuel excavators with on-site refueling, potentially cutting diesel use by 30%. The early results from the Somerset trial are promising, showing that 6,588kWh of power came from solar, 9,171kWh from green hydrogen, and only 287kWh from backup batteries, significantly reducing the need for diesel. The Environment Agency, supporting the trial, sees it as a significant step towards achieving its net-zero goals. The involvement of government funding for green hydrogen projects further emphasizes the commitment to sustainable energy solutions for a greener future.
