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
