Pumped-storage hydropower offers the most cost-effective storage option for shifting large volumes of energy. A PNNL-led team wrote a report comparing cost and performance factors for 10 storage technologies.

PNNL researchers are developing the only tool that can control large-scale distributed energy resources in real time.

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.
