Pumped thermal energy storage (PTES) is a very recent technology that can be a promising site-independent alternative to pumped hydro energy storage or compressed air energy storage, without the corresponding geological and environmental restrictions. Accordingly, this paper presents a full thermodynamic ...
Abstract Among the available energy storage technologies, pumped thermal energy storage (PTES) is emerging as a potential solution for large-scale electrical energy storage with no geographical limitations and high roundtrip efficiencies. However, PTES requires a low-cost high temperature heat source to...

Pumped hydro energy storage is the major storage technology worldwide with more than 127 GW installed power and has been used since the early twentieth century. Such systems are used as medium-term storage systems, i.e., typically 2–8 h energy to power ratio (E2P ratio). Technically, thes...
Pumped hydroelectric storage is currently the only commercially proven large-scale (>100MW) energy storage technology with over 200 plants installed worldwide with a total installed capacity of over 100GW. The fundamental principle of pumped hydroelectric storage is to store electric energy in the for...
