University of Exeter Evaluates Floating PV Potential for 490,000 Households in Hong Kong
Researchers from the University of Exeter have evaluated the potential of floating photovoltaic (FPV) systems on Hong Kong's reservoirs, which could generate up to 4.8 TWh annually, meeting 36.5% of the city's residential electricity needs. With full coverage, FPV could supply 7.72 TWh, sufficient for 490,000 households, while also producing significant quantities of hydrogen for transport. The study indicates that FPV systems have a levelized cost of electricity of $0.037/kWh, highlighting their feasibility for hydrogen integration.

Researchers from the University of Exeter assessed floating PV systems on Hong Kong's reservoirs. With 60% coverage, FPV could generate 4.8 TWh annually, servicing 36.5% of residential electricity needs.
At full coverage, it could supply 7.72 TWh, enough for 490,000 households. The study identified 18 reservoirs, focusing on energy production and hydrogen generation for transport. Annual hydrogen output varies from 180,502 kg to 36,310,221 kg, with levelized costs between $10.2/kg and $19.4/kg. The FPV systems alone yield an LCOE of $0.037/kWh, suggesting feasibility for hydrogen integration.
