Attributes of Bi-Directional Turbomachinery for Pumped Thermal Energy Storage

Journal of Turbomachinery, 2022
Abstract In this paper, we (i) present a methodology for determining the aerodynamic performance of bi-directional turbomachines for pumped thermal energy storage, i.e., turbomachines designed to operate as a compressor in one direction, and then as a turbine in the opposite direction, (ii) carry out performance computations for such ...

Off-design characterisation of a hybrid energy storage based on pumped thermal energy storage and low-concentration solar thermal collectors

2021
Long duration storages (i.e. 6+h) could foster the power sector transitions towards renewable energy sources. Among the many technologies proposed for such a task, pumped thermal electricity storage (PTES) recently gained much attention from researchers.

High-temperature Pumping of Silicon for Thermal Energy Grid Storage

Energy, 2021
Abstract As the cost of renewable energy falls below fossil fuels, the key barrier to widespread sustainable electricity has become availability on demand. Energy storage can enable dispatchable renewables, but only with drastic cost reductions compared to current batteries.

Thermal energy storage using thermo-chemical heat pump

Energy Conversion and Management, 2013
Abstract A theoretical study was performed to investigate the potential of storing thermal energy using a heat pump which is a thermo-chemical storage system consisting of water as sorbet, and sodium chloride as the sorbent. The effect of different parameters namely; the amount of vaporized water from the evaporator, the system initial temperature ...
