Abstract
Nowadays, global warming and energy scarcity have prompted mankind to develop new energy technologies. Given that new energy generation technologies such as solar and wind energy are subject to climatic conditions with factors such as unstable power generation, the storage process of electrical energy is particularly important. Therefore, the importance of hydrogen energy and its storage technology has received increasing attention from researchers based on the advantages of its wide distribution, high calorific value, and lack of greenhouse gas production.This paper summarizes the current research status of various hydrogen storage technologies, and at the same time assesses and compares the gap between each hydrogen storage technology and the commercialization standard. Based on the analysis, two key routes for the future development of hydrogen storage technologies are proposed.
