重力储能技术研究进展

储能技术主要是指电能的储存,是智能电网的重要环节。当前应用最广泛的储能系统为抽水储能,但其选址困难、对环境影响较大、对水资源依赖严重。重力储能作为一种新型的储能技术,以重物为储能媒介,原理简单且形式多样,能够充分发挥不同的地理优势进行储能。相对于传统储能技术,重力储能技术具有非常明显的优势。根据山地重力储能、悬重式重力储能、塔吊式重力储能、铁轨重力储能和重力储能式飞机等5种形式的重力储能技术,对现阶段重力储能技术的研究进展进行了综述。结合重力储能技术的原理、特点以及我国储能领域的发展方向和需求,对重力储能技术的应用前景进行了分析并提出建议。研究内容和提出的建议可以为我国重力储能技术的理论研究和发展应用提供参考。

Research Progress of Gravity Energy Storage Technology

Energy storage technology mainly refers to the storage of electric energy, which is an important part of the smart grid. At present, the most widely used energy storage system is pumped energy storage, while its location is difficult, it damages the environment, and is heavily dependent on water resources. Gravity energy storage, as a new type of energy storage technology, uses heavy objects as energy storage media, with simple principles and diverse forms, which can give full play to different geographical advantages for energy storage. Compared with traditional energy storage technology, gravity energy storage technology has very obvious advantages. In this paper, the research progress of gravity energy storage technology at the present stage was summarized with respect to five types of gravity energy storage technologies, such as mountain gravity energy storage, suspension gravity energy storage, tower gravity energy storage, rail gravity energy storage and gravity energy storage aircraft. Finally, combining the principles and characteristics of gravity energy storage technology and the development direction and needs of China's energy storage field, the application prospects of gravity energy storage technology were analyzed and suggested. The research content and the suggestions put forward can provide references for the theoretical research, development and application of China's gravity energy storage technology.
