Hydrogen cylinders for cars
Anhui clean Energy has been dedicated to the research and development of high-pressure CH4 composite hydrogencylinders for vehicles, collaborating with several chinese universities and research institutions. After relentless effortswe successfuly developed 35MPa and 70MPa high-pressure hydrogen cylinders in 2024. To further enhance productquality, we invested 300 milion RMB in 2023 to build an automated plant. Our goal is to produce 35MPa and 70MPa highpressure hydrogen cylinders that meet Chinese and international high standards and launch them to the market in 2025
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

On-board hydrogen supplysystem
Anhui Clean Energy has been dedicated to the research and development of high-pressure hydrogen cylinders for CH4 composite gas cylinders. After relentless efforts by our technical team, we successfully developed 35MPa and 70MPa high-pressure hydrogen cylinders in 2024. To further enhance product quality, we invested 300 million RMB in 2023 tobuild an automated plant, At the same time, our goal is to produce 35MPa and 70MPa high-pressure hvdrogen cylinders that meet domestic and international high standards and launch them to the market by 2025
Product principle ofvehicle hydrogen supplysystem
