Is pumped hydro storage critical

What is pumped hydro energy storage?

The pumped hydro energy storage (PHES) is a well-established and commercially-acceptable technology for utility-scale electricity storage and has been used since as early as the 1890s.

What are the research trends in pumped hydro energy storage?

Journal of Energy Storage is the leading journal in the research area. Large-scale energy storage solutions have become increasingly critical as the global energy sector shifts towards renewable sources. This study conducted a comprehensive bibliometric analysis of global research trends in pumped hydro energy storage (PHES) from 2003 to 2023.

What are the drivers of pumped hydro storage?

Among the drivers, pumped hydro storage as daily storage (TED2.1), under the utility-scale storage cluster, was the most important driver, with a global weight of 0.148. Pumped hydro's ability to generate revenue (SED1.1), under the energy arbitrage cluster, was the second most prominent driver, with a global weight of 0.096.

Are pumped hydro energy storage solutions viable?

Feasibility studies using GIS-MCDM were the most reported method in studies. Storage technology is recognized as a critical enabler of a reliable future renewable energy network. There is growing acknowledgement of the potential viability of pumped hydro energy storage solutions, despite multiple barriers for large-scale installations.

Should pumped hydro energy storage be viewed in isolation?

The analysis suggests that pumped hydro energy storage is not viewed in isolation but as part of a broader ecosystem of renewable energy technologies and grid management strategies.

Is pumped hydro storage a key technology for energy transition?

The global distribution of research efforts indicates that pumped hydro storage is recognised as a crucial technology for energy transition worldwide, with established and emerging economies contributing significantly.
