Why is hydrogen storage important?

Hydrogen energy has emerged as a pivotal pathway for facilitating the global energy transition. The efficient and safe operation of hydrogen storage equipment is important for hydrogen widespread application, while high-pressure gaseous hydrogen storage technology has emerged as the prevailing technique due to its advantages.

What is the development status of high-pressure gaseous hydrogen storage equipment in China?

This article reviews the current development status and challenges of high-pressure gaseous hydrogen storage equipment in China. With regard to stationary vessels, China has introduced an innovation in the form of a multifunctional layered steel vessel to reach a good balance between hydrogen embrittlement control and cost management.

What is the ideal storage pressure for a hydrogen supply system?

Hydrogen storage density and cost are related to pressure [64, 65]. Considering factors such as compressed energy consumption, driving range and infrastructure construction investment, the current ideal storage pressure for on-board hydrogen supply systems is 35 and 70 MPa.

How many hydrogen refueling stations are there in China?

However, their most common usage can be observed in hydrogen refueling stations [28, 29]. China has currently established over 350 hydrogen refueling stations. These stations are supported by over 2000 stationary HPGH 2 storage vessels that are currently in operation. 2.1.1. Single-layer seamless

What is a hydrogen storage well?

Hydrogen storage wells are a fusion of oil and gas well technology and pressure vessel technology. These wells possess unique advantages, such as a small footprint and minimal consequences in case of failure due to their underground location.

What is the demand for hydrogen storage vessels in China?

The demand of Hydrogen storage vessels with a capacity of tons is increasing rapidly. Type IV cylinders of 400 L and larger for truck are developing rapidly in China. The non-destructive testing methods for on-board cylinders require further research.
