100% renewable targets will require power storage to manage flows on the net
Electrolysers utilise these intermittent power flows to produce H2 gas from water
H2 gas can be stored in large quantities underground and transported via existing gas pipelines
H2 vehicles recharge faster and are more durable than battery powered transport
Growing H2 demand in industrial processes will reduce costs and increase supply

UK independent fuel cell supplier UPS Systems has installed an SFC EFOY Pro 2200 DMFC at the Environment Agency’s Woolston Weir fishery. The installation will power a new eel pass monitoring the endangered species’ upstream journey to fresh water. The fuel cell has been installed alongside two load-carrying batteries hooked up in parallel. The DMFC acts as a charger to ensure the batteries are kept at optimum voltage at all times. The system provides continuous power to a water pump that oxygenates a holding tank where the eels are counted and checked. It also powers a web cam and the telemetry system.

The number of young eels migrating into European rivers has fallen to less than 5% of 1980s levels; the newly designed pass has been designed to allow the easy movement of eels between stretches of river, overcoming the potential obstacle that older-style flap gates posed. With zero emissions and near-silent operation the system won’t interfere with the eels’ natural habitat.
