摘要

随着可再生能源的快速发展，储能技术作为一种提供平稳、连续电力的关键手段受到了广泛关注。重力储能技术以其原理简单、成本低、容量大、效率高、安全可靠等优点，成为一种新兴的机械EST技术。本文根据不同的存储介质和计算原理，将GES分为流体GES、固体GES和颗粒GES，首次定义了颗粒GES，并对其相关技术进行了深入的分析和讨论。通过比较不同GES的特点、现状、优缺点，总结出影响效率的因素，总结出比较和选择的方法。这表明GES可以与其他无害环境技术相辅相成，促进可再生能源的发展。GES商业化项目已经实施，需要根据运行数据反馈评估其平准化储能成本（LCOS），同时明确行业指标，探索稳定的发展模式。

Gravitational energy storage: Media taxonomy, efficiency factors, comparison and selection

Energy storage technology (EST) has gained widespread attention as a key method of providing smooth and continuous electrical power with the rapid development of renewable energy sources. Gravitational energy storage (GES) has become an emerging mechanical EST due to its simple principle, low cost, large capacity, high efficiency and safety. This paper classifies GES into fluid GES, solid GES and particle GES according to different storage mediums with calculation principles, defines particle GES for the first time, and provides in-depth analyses and discussions on its related technologies. By comparing characteristics, status quo, advantages and disadvantages of different GES, efficiency impact factors are concluded, comparison and selection methods are summarized. It shows GES can complement other ESTs to promote renewable energy development. GES commercialization projects have been implemented, and need to assess their levelized cost of storage (LCOS) based on operational data feedback while clarifying industry indicators and exploring a stable development model.

期刊介绍： Applied Energy serves as a platform for sharing innovations, research, development, and demonstrations in energy conversion, conservation, and sustainable energy systems. The journal covers topics such as optimal energy resource use, environmental pollutant mitigation, and energy process analysis. It welcomes original papers, review articles, technical notes, and letters to the editor. Authors are encouraged to submit manuscripts that bridge the gap between research, development, and implementation. The journal addresses a wide spectrum of topics, including fossil and renewable energy technologies, energy economics, and environmental impacts. Applied Energy also explores modeling and forecasting, conservation strategies, and the social and economic implications of energy policies, including climate change mitigation. It is complemented by the open-access journal Advances in Applied Energy.
