Pumped thermal energy storage (PTES or Carnot battery) converts electric energy to thermal energy with a heat pump (or another heating system) when electricity production is greater than demand; when electricity demand outstrips production the PTES generates power from two thermal storage reservoirs (...

Due to their independence from geographical and geological requirements, Pumped Thermal Energy Storages (PTES) are a possible form of energy storage in system-relevant orders of magnitude for these requirements. Compared to electric resistance heaters, the round trip efficiency can be significantly ...
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...
Storage is feasible with pumping stations. Pumped storage is a potential efficient driver of energy saving when coupled with inflexible installations (such as thermal plants) or intermittent installations (such as windmills and solar batteries). The model developed in this paper ...
