Researchers from the University of Exeter evaluated the potential for integrating floating photovoltaic (FPV) systems with green hydrogen production on UK reservoirs, specifically at Killington and Drift Reservoirs. The study found that hydrogen utilization for heat production offers the greatest potential due to fewer energy conversion losses. Maximum FPV deployment could generate significant amounts of electricity and hydrogen, while also conserving water through reduced evaporation beneath the floating PV arrays. This research highlights the potential for FPV systems to contribute to both renewable energy generation and water conservation, emphasizing their role in decarbonizing energy-consuming sectors in the UK.
