Pumped storage hydropower (PSH) operates by storing electricity in the form of gravitational potential energy through pumping water from a lower to an upper reservoir. First built since the end of 19th century, PSH is a mature and proven technology for long duration energy storage. It has continuously evolved to suit the needs of changing power systems, providing a suite of power system flexibility services such as inertia, frequency control, voltage regulation, and black–start capability, which are vital to support the growing shares of variable renewable energy in grid systems. However, it is often absent in discussions concerning the need and deployment of energy storage due to lack of understanding and perceived geographic limitations.
To this end, we have called for short technology profiles to be submitted that describe new approaches to energy storage with pumped storage hydropower as a base. The goal of this report is to improve the understanding of innovative PSH technologies and to explore potential benefits and opportunities based on physics and evidence.
