“…They showed that overall energy and exergy efficiencies of 72.1% and 53.7%, respectively, could be achieved. Vecchi et al [156] performed a techno-economic analysis on an LAES-based system for heating, cooling and power applications, and showed that the RTE of the overall system increased by 54.8%, and the operational cost was reduced by 8%-12%. A summary of the waste heat utilization approaches is provided in table 6.…”

Liquid air energy storage (LAES) uses air as both the storage medium and working fluid, it falls into the broad category of thermo-mechanical energy storage technologies. Such a technology offers several advantages including high energy density and scalability, cost-competitiveness and non-geographical constraints, and hence has attracted a growing interest in recent years. As a result, several reviews have been published on the topic. However, these reviews covered little in the following aspects of LAES: dynamic simulation and optimisation, key components for LAES, LAES applications through integration, and unified economic model and cost models for LAES. This article provides a comprehensive review on the LAES technology and fills the above gaps. Apart from applications in electrical grids such as peak-shaving, load shifting, and dealing with intermittency of renewable generation, the review also shows a diverse range of other LAES applications through integration, including waste heat and cold energy recovery and utilisation, multi-energy-vector service provision, and sector coupling for chemical production and carbon capture. The review also led to the recommendation of several areas of LAES for future research and development, including dynamic characteristics of whole LAES system integrated with renewables and end users; thermo-economic and dynamic optimization of stand-alone LAES and integrated systems; and experimental study on commercial systems.

“…They also investigated the techno-economic value of LAES to supply electricity, heating and cooling functions simultaneously. The vector-coupling capability of LAES is capable of achieving a 35% of increase in energy efficiency and a 8-12% of decrease in system operational cost (Vecchi et al, 2021). However, the interactions of the gird-scale LAES system with other power generators were not studied.…”

“…CBs are emerging as an alternative grid-scale storage technology due to their long operational life (20-30 years), low cost per kWh [8] and independence from rare raw materials. Since CBs are gaining interest, many technologies have been proposed in the scientific literature for MES optimization, including Liquid Air Energy Storage (LAES) [9], Compressed Air Energy Storage (CAES) [10], Rankine-based Pumped Thermal Energy Storage (Ra-PTES) [11], and Brayton-based Pumped Thermal Energy Storage (Br-PTES) [12]. Despite these positive features, the economic advantages of using CBs as a pure electric-toelectric storage capacity are still not clearly assessed [13].…”

Grid-scale energy storage systems are essential to support renewables integration and ensure grid flexibility simultaneously. As an alternative to electrochemical batteries, Pumped Thermal Energy Storage is a new storage technology suitable for grid-scale applications. This device stores electric energy as thermal exergy, which can be discharged directly for thermal uses or converted back into power depending on the necessities of the grid. The capability of the proposed energy storage to act as electric and thermal storage fits with the sector coupling necessities of multi-energy systems in which electrical and thermal energy carriers are involved. This paper investigates the effects on optimal grid management of integrating a Brayton Pumped Thermal Energy Storage into a multi-energy system. The case study includes renewable generation from photovoltaic modules and residential and industrial users' electrical and thermal load profiles. The system day-ahead optimization, performed through a Mixed Integer Linear Programming approach, aims to minimize the operational cost computed over a 24-hour horizon. The simulation highlights how the proposed storage technology interacts with the users' requirements during different seasons. The final results highlight that using multi-energy storage (i.e., providing power, heating, and cooling) brings a 5% reduction in operating costs during the year compared to a traditional electric-to-electric storage operation.
