Sizewell C in Suffolk is testing the operational performance of three hydrogen double-deck buses and one single-deck bus to transport workers during the construction phase. This move aims to reduce carbon emissions and limit the impact of workforce transport on the local area. If successful, Sizewell C plans to order up to 150 hydrogen buses, creating the UK’s largest hydrogen bus fleet. The project also considers using electric buses in its zero-emissions fleet. By partnering with UK businesses like Wrightbus, the initiative supports the growth of green jobs and the hydrogen economy in the East of England. Furthermore, the trial could drive hydrogen production in the region and help address supply and demand challenges. With government funding, the project is pioneering mobile hydrogen refuelling systems to reduce fossil fuel usage. Sizewell C's efforts align with the UK Government's hydrogen policy, aiming to advance net zero technologies and reduce carbon emissions during the construction of the nuclear power station.
