Attributes of Bi-Directional Turbomachinery for Pumped Thermal Energy Storage
… performance of bi-directional turbomachines for pumped thermal energy storage, i.e., turbomachines designed to operate with both forward and backward flow, (ii) carry out performance computations for such turbomachines, and (iii) propose principles for conceptual design of these devices. Focus is …

Analysis and optimisation of thermal energy storage
The focus of this project is the storage of thermal energy in packed beds for bulk electricity storage applications. Packed beds are composed of pebbles through which a heat transfer fluid passes, and a thermodynamic model of the heat transfer processes within the store is described. The packed …

A comparative analysis and optimisation of thermo-mechanical energy storage technologies
Electrical Energy Storage (EES) can decouple energy production from its consumption and is urgently needed by both conventional energy system for load leveling and renewable energy system for intermittency smoothing. Currently, Pumped Hydro Energy Storage (PHES) and Compressed Air Energy Storage …

Modelling and development of thermo-mechanical energy storage
Pumped thermal energy storage (PTES) and liquid air energy storage (LAES) are two technologies that use mechanically-driven thermodynamic cycles to store electricity in the form of high-grade thermal energy, employing abundant materials that are kept in large insulated tanks. Both technologies are …

Low temperature glide cycles for energy storage applications: Thermodynamic and capital cost analysis
… being researched for grid-scale electricity storage, pumped thermal energy storage consists of storing electricity as thermal energy, with the conversions being done by a reversible heat pump/heat engine system. Advantages include the use of abundant and cheap materials, conventional …

Chemical Looping Electricity Storage
Developing grid-scale energy storage technologies is the key element for broader deployment of renewable sources of energy. This is due to bench-mark technologies like pumped hydro and compressed air being geographically restricted, i.e. require large reservoirs to store air/water, new storage …
