Energy storage cylinder structure

What is a hydrogen storage cylinder?

Hydrogen storage cylinders play a crucial role in storing and transporting hydrogen gas, highlighting their essential safety considerations in hydrogen energy applications. The history of hydrogen storage cylinders dates back to the late 19th century, originally meeting the gas industry's demands.

How are energy storage accumulators arranged?

One chamber is arranged to the energy storage accumulator for energy saving. Other chambers are flexibly connected to the pump ports for variable transmission ratios. Areas of multiple chambers are designed to permit a symmetric single-rod cylinder. Three modes are switched by solenoid valves to expand force-velocity capabilities.

What is the structure of a gas cylinder?

The structure of the base end consists of three parts: the approximate spherical shell, the ring shell and the transition region. The typical characters of gas cylinder are the cylindrical part, the transition region, the ring shell and the spherical shell are in turn connected with each other.

Does a hydrogen storage cylinder have a concave bottom?

Although hydrogen has an effect on the initiation and growth of fatigue cracks, a reasonable structure of cylinder will make the stress distribution more reasonable and reduce the probability of crack initiation from the source. This paper researched the multi-center concave bottom for hydrogen storage cylinder.

What are the characteristics of a gas cylinder?

The typical characters of gas cylinder are the cylindrical part, the transition region, the ring shell and the spherical shell are in turn connected with each other. The security of the concave base end of gas cylinder is closely related to the structure of the base end. Fig. 1. A structure schematic of multi-center concave base end 1.

Are hydrogen storage cylinders subject to fire?

Failure modes and evolution mechanisms of hydrogen storage cylinders subjected to fire were revealed. As the most common containers for hydrogen fuel cell vehicles, the development of hydrogen storage cylinders has attracted significant attention.
