Pumped Thermal Electricity Storage | Concentrating Solar Power | NREL
Known as pumped thermal electricity storage—or PTES—these systems use grid electricity and heat pumps to alternate between heating and cooling materials in tanks—creating stored energy that can then be used to generate power as needed. Coupled with CSP systems, this new technology can increase plant efficiency, …

Supercritical CO2-Based Heat Pump Cycle for Electrical Energy Storage for Utility Scale Dispatchable Renewable Energy Power Plants
The AMSES system consists of around 200 MW charging power and 100 MW discharging power with 8 hours of storage (i.e. around 40 ktons of molten salt). The number of hours of the storage is varied to check its influence on the levelised cost of electricity.

Design aspects of a reversible heat pump
Introduction A rising ratio of renewable energies results in the need for buffering the fluctuating energy input via storage systems [1]. So far, pumped-hydro is the large scale energy storage mainly used. One new interesting aproach are the Pumped Thermal Electricity Storages (PTES) or Carnot Batteries [2]. [2].
