Abstract

The invention relates to the technical field of energy storage and discloses a gravity energy storage system and an application method thereof. The gravity energy storage system comprises mass blocks,a bearing structure and lifting structures, wherein the bearing structure comprises fixing parts and a plurality of load-bearing walls; the plurality of load-bearing walls are arranged in parallel atintervals; a lifting channel is formed between every two adjacent load-bearing walls; the fixing parts are connected to the load-bearing walls and located in the lifting channels; the fixing parts are used for bearing the mass blocks; each lifting structure comprises a traveling crane; a motor device in each traveling crane is a generator motor; and the traveling cranes are mounted at the top ends of the load-bearing walls and used for carrying the mass blocks. Through the structure, the gravity energy storage system has the low requirement for geographical conditions and is small in occupiedarea.

Description

technical field [0001] The invention relates to the technical field of energy storage, in particular to a gravity energy storage system and a method for using the same. Background technique [0002] At present, with the rapid development of new energy and energy Internet, the power industry has put forward an urgent need for large-scale power storage technology. [0003] In recent years, chemical energy storage technology has developed vigorously, especially lithium battery energy storage technology has been rapidly developed and widely used, and has become the mainstream chemical energy storage method. However, lithium battery energy storage itself also faces challenges in terms of cycle times, safety, cost, etc., and its safety and economy are still insufficient. In contrast, although physical energy storage technology is highly safe and economical, the commonly used energy storage method is still pumped storage. This method is limited by geographical conditions and is di...
