Knowledge fuels change - Support energypedia!
For over 10 years, energypedia has been connecting energy experts around the world — helping them share knowledge, learn from each other, and accelerate the global energy transition.
Today, we ask for your support to keep this platform free and accessible to all.
Even a small contribution makes a big difference! If just 10–20% of our 60,000+ monthly visitors donated the equivalent of a cup of coffee — €5 — Energypedia would be fully funded for a whole year.
Is the knowledge you’ve gained through Energypedia this year worth €5 or more?
Your donation keeps the platform running, helps us create new knowledge products, and contributes directly to achieving SDG 7.
Thank you for your support, your donation, big or small, truly matters!
Grid Energy Storage
Introduction
In order to cope with both high and low load situations, the storage of electricity is of great importance. However, the large-scale storage of electricity in the grid is still a major challenge and subject to research and development.
The following technologies and approaches can, or are hoped to, provide a solution to storing electricity and balancing supply and demand in modern electricity grids.
Pump storage hydropower
A pumped storage hydroelectricity system (PSH) consists of two water reservoirs at different elevations. Low-cost surplus electric power is typically used to pump water into the upper reservoir. During periods of high electricity demand, the stored water is released through turbines to generate electricity.[1][2]
