Using gas compressibility, conventional natural gas is stored under high pressure, and the storage pressure is usually 15-25 MPa. For example, in the case of 25 MPa, natural gas can be compressed to 1/300 of its original volume. The storage volume is greatly reduced, but due to the high storage pressure, the requirements for the gas cylinder are higher.

The current gas cylinders are mostly made of high-strength alloy structural steel with high quality. Take a bus as an example. If you use gasoline and diesel as a fuel addition cycle every 300 km, you usually need to be equipped with about 6 50L gas storage cylinders with a total mass of about 360kg, while the fuel mass at full capacity is only It is 1/6 of the quality of the steel cylinder. For this reason, it can be alleviated by optimizing the determination of the fuel addition cycle, the gas storage capacity of the gas cylinder, the gas storage volume, and the reasonable setting of the gas filling station.

The optimization of the shape of the gas cylinder not only takes into account the improvement of the force of the container, reduces the wall thickness of the container, and reduces the quality, but also considers the full and reasonable use of the limited space of the vehicle. The improvement of the material of the gas cylinder is to solve the potential for corrosion of the inner and outer walls of the cylinder. At the same time as the dangerous factors, the quality of the gas storage container is also reduced to better meet the requirements of use.

Theoretically, under a certain gas storage pressure, the mass per unit volume of a compressed natural gas storage cylinder is an important indicator to measure its pros and cons. According to statistics, the unit volume mass of domestic gas cylinders is generally more than 1 kg, while imported thin-walled cylinders are about 0.8kg, while the unit volume mass of aluminum alloy gas cylinders can be reduced to less than 0.6kg, and carbon material gas cylinders are even lower.
