Pumped Storage Hydropower: A Key Part of Our Clean Energy
A new form of PSH, called Ground-Level Integrated Diverse Energy Storage (GLIDES) systems, pumps water into vessels full of air or other pressurized gases.

Understanding the Function of Accumulators
When storing energy, they receive pressurized hydraulic fluid for later use. Sometimes accumulator flow is added to pump flow to speed up a process. Other times the stored energy is kept in reserve until it is needed and may be independent of pump flow. This could be for emergency power when pump flow is not available.
