Pumped hydro storage, when combined with other energy storage technologies, can provide a greater range of services while also enhancing overall system reliability – especially if it is also coupled with off-grid renewable energy. This is one of the main findings of the study Solar-wind-pumped hydro energy storage systems: review and future perspective, published on the ScienceDirect website. The research – which was conducted by scientists from Shanghai Jiao Tong University, Sweden’s Mälardalen University, and Poland’s AGH University of Science and Technology – provides an extensive review of pumped hydro storage facilities combined with hybrid solar-wind power supply systems across the world. The study also analyzes several simulation methods and other techniques to determine the optimal size of renewables-based pumped hydro storage systems.
