Floating Solar Could Power 40% Of The World
Untapped Potential Exists for Blending Hydropower, Floating PV
Sept. 29, 2020 (National Renewable Energy Laboratory)
Hybrid systems of floating solar panels and hydropower plants may hold the technical potential to produce a significant portion of the electricity generated annually across the globe…[The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) estimated] that adding floating solar panels to bodies of water that are already home to hydropower stations could produce as much as 7.6 terawatts of potential power a year from the solar PV systems alone, or about 10,600 terawatt-hours of potential annual generation.
Those figures do not include the amount generated from hydropower…[G]lobal final electricity consumption was just over 22,300 terawatt-hours in 2018, the most recent year for which statistics are available…NREL estimates 379,068 freshwater hydropower reservoirs across the planet could host combined floating PV sites with existing hydropower facilities…Additional siting data is needed prior to any implementation because some reservoirs may be dry during parts of the year or may not be otherwise conducive to hosting floating PV…
...[A] hybrid system would reduce transmission costs by linking to a common substation. Additionally, the two technologies can balance each other. The greatest potential for solar power is during dry seasons, while for hydropower rainy seasons present the best opportunity…[O]perators of a hybrid system could use pumped storage hydropower to store excess solar generation…” click here for more
