CNG Storage Systems

Reliable CNG Storage Systems for Safe and Efficient Natural Gas Storage

DSW supplies high-performance CNG storage systems for the safe storage, transport, and distribution of compressed natural gas across refuelling stations, industrial facilities, energy projects, and fleet fueling applications.
Designed for high-pressure performance, safety, and long-term reliability, our solutions support CNG refuelling stations, daughter stations, virtual pipelines, and industrial gas supply networks.

What Is a CNG Storage System?

A CNG storage system is an integrated solution for storing and managing compressed natural gas at high pressure, typically 200–250 bar or higher depending on the application.
It commonly includes high-pressure cylinders, storage cascades, manifolds, pressure control equipment, safety valves, and skid-mounted structures to ensure stable gas supply and efficient pressure management.
Common applications include:

• CNG refuelling stations
• Mother and daughter stations
• Virtual pipeline transportation
• Industrial gas supply systems
• Backup fuel gas systems
• Power generation projects
• Fleet fueling infrastructure

These systems improve refuelling efficiency, maintain stable pressure, and enhance operational safety.
