Pumped Hydro Moves to Retain Storage Market Leadership

In recent years, energy storage installations around the world have been dominated by lithium-ion battery technology. But pumped hydro, for decades the only utility-scale storage asset available and still the leader with 95 percent of storage’s global capacity, isn’t giving up just yet. 

This week, the International Hydropower Association and the U.S. Department of Energy announced an alliance of 11 national governments and more than 60 organizations to speed up the development and deployment of pumped hydro projects around the world.
