Integration of Run-Of-River Hydropower with Energy Storage …
The team demonstrated that integration of energy storage (e.g., batteries, flywheels, and/or ultracapacitors) can enable a run-of-river hydropower plant to perform similarly to a hydropower plant with reservoir storage.
Hydropower Basics
What is Hydropower? Hydropower, or hydroelectric power, is one of the oldest and largest sources of renewable energy, which uses the natural flow of moving water to generate electricity. Hydropower currently accounts for nearly 27% of total U.S. utility-scale renewable electricity generation and 5.7% of total U.S. utility-scale electricity generation.
