Research Progress of Power Generation Technology Using Gravity Energy Storage in a Context of Carbon Neutrality

Abstract

As the global economy improves by leaps and bounds, the skyrocketing energy consumption caused by the increase in population and rapidly developing in urbanization and industrialization has brought many serious challenges, such as global warming, environmental pollution, ecological damage, and resource scarcity. To solve these problems, countries are actively developing and utilizing energy resources to generate electricity, such as solar photovoltaics, wind, geothermal energy, ocean energy, and biomass. However, they cannot meet the growing electricity demand because of their intermittency and instability, and geographical constraints. Thus, the quest to discover innovative, sustainable, and effective modes of energy conversion and storage has emerged as one of the foremost critical concerns on the global stage. Compared to traditional electrochemical energy storage technologies, gravity storage offers higher safety, larger storage capacity, and lower environmental damage and significantly reduces the dependence on geographical conditions and water resources, with great potential for application.
