Western China's First Automated Type IV Hydrogen Storage Cylinder Production Line Rolls Off the Line

Shaanxi Hydrogen Energy Hydrogen Storage Equipment Technology Co., Ltd. has completed the first automated Type IV hydrogen storage cylinder production line in western China, with the products rolling off the line at the Type IV Cylinder Technology Transformation Center in Yuyang Economic-Technological Development Zone.

Type IV hydrogen storage cylinders feature a fully wrapped composite structure with a plastic liner reinforced by carbon fibre. They offer advantages including lightweight design, high hydrogen storage density and long service life, making them a key component in hydrogen storage and transportation. The cylinders can be widely used in hydrogen-powered heavy-duty trucks, drones and other on-board and specialised hydrogen-energy equipment.

The newly completed automated pilot production line was invested in and built by Shaanxi Hydrogen Energy Hydrogen Storage Equipment Technology Co., Ltd. It is designed to produce 5,000 Type IV high-pressure hydrogen cylinders annually and supports both 35 MPa and 70 MPa pressure ratings, with product capacities ranging from 20 litres to 450 litres.

The production line is equipped with dedicated equipment including high-precision injection-moulding systems, high-precision infrared welding stations and controlled fibre-winding equipment. It also features a digital-twin-based quality control system to support standardised and regulated pilot production.

The line is expected to support the commercialisation of hydrogen-energy technologies in heavy-duty transport and the low-altitude economy.

The completion of the automated Type IV hydrogen storage cylinder production line fills a gap in the region’s high-end hydrogen storage equipment manufacturing sector. It is also a landmark project for Yuyang Economic-Technological Development Zone as it seeks to foster new quality productive forces and accelerate the transformation and upgrading of the local energy industry.

The development zone said it will continue to improve its business environment, strengthen support for key resources and provide full-cycle services for enterprises. It will also build industrial matchmaking platforms to extend and strengthen the hydrogen value chain and attract more upstream and downstream companies to the region.

In recent years, Yuyang Economic-Technological Development Zone has positioned hydrogen  as a key driver of new quality productive forces, in line with Yulin’s goal of building a national innovation demonstration zone for the energy revolution. The zone has continued to attract and develop projects, strengthen innovation platforms and accelerate the implementation of major industrial initiatives.

Going forward, the development zone will leverage its position as a provincial-level economic-technological development zone to strengthen innovation, improve enterprise services and accelerate the industrialisation of hydrogen technologies. It aims to build a more complete hydrogen industrial ecosystem and support the region’s green, low-carbon and high-quality development.
