Norwegian Researchers Address Gas Supersaturation in Hydropower Plants Impacting Aquatic Life

HYDRO POWER

Norwegian researchers from the Norwegian University of Science and Technology are addressing gas supersaturation in hydropower plants, which poses a threat to aquatic life, particularly fish and bottom-dwelling animals. The DeGas project, led by Professor Ole Gunnar Dahlhaug, aims to mitigate these risks using an acoustic transducer to eliminate dissolved air in water, with initial tests showing significant flow rate improvements. The researchers emphasize the need for enhanced monitoring regulations, as current measures are inadequate to protect ecosystems from high levels of air saturation recorded at various power plants.
