Car compressed hydrogen plastic inner carbon fiber fully wound gas cylinder(35Mpa)

Hydrogen  cylinders for cars

Anhui Clean Energy has been dedicated to the research and development of vehicle high-pressure CH4 composite hydrogen cylinders. We have collaborated with multiple domestic universities and research institutions to develop these cylinders. Finally, in 2024, we successfully produced high-pressure hydrogen cylinders of 35MPa and 70MPa. In order to further enhance product quality, we invested CNY 300 million in 2023 to construct an automated factory. Our goal is to manufacture 35MPa and 70MPa high-pressure hydrogen cylinders that meet both domestic and international standards by 2025, and subsequently release them into the market.

Hydrogen cylinder product advantages

• Safer, plastic liner does not exist grain boundaries, will not occur stress corrosion and hydrogen embrittlement;
• The pressureis higher,35/70MPais widely used;
• High mass density of hydrogen storage, more than 20% higher than the three-type bottle;
• Low weight, three type bottle liner weight is larger;
• The cost is lower than the three-type bottle products, and theinner liner material is different;
• The fatigue performance is good, and the fatigue life is more than 2 times longer than that ofthe three-type bottle
• The product with the same diameter and volume has small weight, low weight ratio and good economic benefit

Quality Control

Our products have ISO 11439, ISO11119, ISO9089, UN ISO9809, ECE R110, EN11245 and other international certificates, as well as the company's own ISO9001 and IATF 16949 and other international quality system certificates. We know that you want to keep improving the quality of your products. We, on the other hand, focus on details, on quality. Because we believe that every smallest step affects the value and quality of the final product.

Since its establishment over ten years ago, the company has a self-built factory covering an area of 56,000 square meters.  We currently have a workforce of 240 employees, including 50 senior technical and management personnel.  Additionally, we possess the production capacity to manufacture 300,000 various types of gas cylinders per year, as well as 9,000 sets of CNG framework assemblies and gas supply systems.
