Understanding Pumped Hydro Storage as a Renewable Energy

An open-loop system does feed into local water flows like rivers. This can affect local wildlife and the environment more than a closed-loop setup. Interestingly, the U.S. Department of Energy states that new pumped hydro storage plans will produce electricity at around $165 per kilowatt-hour (kWh). That compares to $362 per kWh for Li-ion
