Friday, December 6, 2024 This article provides an overview of Pumped Hydro Storage (PHS), a cost-effective and mature technology for large-scale renewable energy storage. PHS systems store energy by pumping water from a lower to an upper reservoir during off-peak periods and releasing it during peak demand to generate electricity. The article covers key components, such as reservoirs, tunnels, and turbines, and discusses different machine configurations, including pump-as-turbine (PAT) systems, which offer cost-effective solutions. It also explores the economic considerations, recent advancements in technology, and ongoing research in the field, emphasizing the importance of efficiency and cost-effectiveness for successful PHS projects.
