Detection indicators and evaluation methods of hydrogen energy storage systems

Abstract

Hydrogen energy storage system is a solution for the consumption of new energy and the construction of a new distribution system. This paper proposes a comprehensive evaluation method for high-pressure gaseous hydrogen energy storage system based on fuzzy analytic hierarchy process. Around the evaluation criteria of technology, safety, economy, and environment, a multi criteria detection index system and evaluation model for hydrogen energy storage system are established. The fuzzy analytic hierarchy process is used to comprehensively evaluate the four aspects of the first and second level evaluation indicators of the high-pressure gaseous hydrogen storage system, which solves the uncertainty problem in the evaluation process. The calculation example shows that in high-pressure gaseous hydrogen storage systems, when using the same type of Type III bottle, the evaluation of a 35MPa hydrogen storage system is slightly higher than that of a 70MPa hydrogen storage system. This method lays a theoretical foundation for the large-scale development of the hydrogen energy storage industry in the future.
