Fuel cell at the sluice

Cutting-edge power is harnessed to manage a Norfolk river’s water levels It used to be done manually. But now, in a harmonious marriage of future resources with ancient needs, both solar energy and hydrogen fuel cell power are being used to control the gates of White Bridge sluice on the River Deben. If these gates aren’t opened at the right moment according to the water level, the area can flood or the river run dry. This requirement for accurate timing led the Environment Agency to seek an automated system, rather than go on relying on physical intervention by its workers. White Bridge, however, may be close to a 12th century abbey and the ruins of a priory, but it’s a long way from a grid connection. So the gas company BOC and Norfolk-based control system specialists Dabbrook Power Systems came up with a hybrid micro-generation solution. It’s based on a limited array of solar photovoltaic cells, and hydrogen fuel cell power, which kicks in during the more challenging winter months. The system is being trialled for 12 months to determine how much fuel is required, how much power can be generated, and, most importantly, whether this is a practical combination for more general off-grid use. - Roger East
