A new paper found that hydropower turbines with composite blades generate about 20 percent more power than turbines with traditional stainless steel blades at the same flow rate.

Researchers at PNNL are now leading research to mitigate biofouling and its impacts on the environment and industry

Researchers at PNNL used key metrics to develop visualizations that show how the combined effects of climate change on hydropower and load influence the frequency, duration, and severity of power shortfalls.

Changes in water volume tend to be smaller in managed watersheds but occur earlier.

PNNL is studying the movement of lamprey fish, which are culturally and historically important to the Pacific Northwest, on rivers and through hydroelectric dams.

Oil spills could be cleaned up in the icy, rough waters of the Arctic with a chemically modified sawdust material that absorbs up to five times its weight in oil and stays afloat for at least four months.
