液化空气储能技术研究综述

A Review on the Research of Liquefied Air Energy Storage Technology

液化空气储能(LAES)是一种以空气为存储介质和工作流体的储能技术,属于热能-机械能储能技术的范畴。LAES技术具有高能量密度、可扩展性、成本竞争力高和不受地理条件限制等优势,近年来引起了越来越多学者的兴趣。然而,这些综述很少涉及以下方面:LAES的工作原理、LAES的关键组件、LAES实验建模以及LAES与其他系统的集成。本文对LAES技术进行了全面综述,填补了上述空白。除了在电网中的应用,如调峰、负荷转移和处理可再生能源发电的间歇性,还介绍了通过LAES与其他外界能量集成其他各种应用,包括废热和冷能的回收和利用和与化学生产部门的耦合,本研究为液化空气储能技术的未来研究和开发提供了理论依据。

Air liquide energy storage is an energy storage technology that uses air as the medium and working fluid,which belongs to the category of thermal-mechanical energy storage technology.LAES technology has the advantages of high energy density,scalability,high cost competitiveness and geographical constraints,which has attracted more and more scholars in recent years.However,these reviews rarely address how LAES works,key components,experimental models,and integration of LAES with other systems.This article fills the above gaps by providing a comprehensive review of LAES technology.In addition to applications in the grid,such as peak shaving,load shifting and dealing with the intermittency of renewable energy generation,the paper also introduces various other applications through LAES integration with other external energy,including the recovery and utilization of waste heat and cold energy and coupling with the chemical production sector.It provides a theoretical basis for the future research and development of air liquide energy storage technology.
