Metrobus in Croydon has launched the first double-decker hydrogen-powered buses on the 420 route, with plans to expand to over 40 buses. The partnership with West Sussex, Surrey, and Kent county councils, along with Gatwick, involves a £24 million investment. The buses offer zero emissions, with only water vapor released, supporting a cleaner environment. Hydrogen can be sourced from carbon-neutral sources like waste or renewable energy, enabling emission-free energy. With a range similar to diesel vehicles and quick refueling, the buses aim to provide sustainable transport options. Metrobus's commercial director highlights the importance of the investment in zero-emission buses for the community, emphasizing the reduction of carbon emissions. The project showcases the benefits of partnership working and prioritizing local transport needs. Future routes including Caterham, Dorking, and Brighton will also incorporate hydrogen-powered buses, promoting sustainable travel in rural areas.
