Next-Generation Ground Gas Storage: High-Pressure Composite Vessels for Hydrogen, CNG, and Industrial Applications

Steelhead Composites ground storage vessels represent a breakthrough in stationary high-pressure storage. These advanced composite tanks are lighter, easier to install, and deliver more usable volume per footprint than traditional steel tanks.

With pressure ratings up to 700 bar and modular deployment options, they are ideally suited for renewable hydrogen hubs, CNG refueling stations, and industrial buffering. Minimize infrastructure, maximize energy.

Uses and Applications
Hydrogen storage

Hydrogen – Stationary Energy Storage

Ideal for renewable hydrogen hubs and electrolyzer sites, these tanks offer reliable high-pressure storage with a compact footprint.

Medical gases storage solutions

CNG Infrastructure – Lab Gases

Perfect for CNG refueling stations or controlled lab environments, they provide safe and efficient storage of compressed gases.

Hydrogen storage for reserach facilities

Research Facilities – Compressor Buffering

Used as buffer storage for high-performance compressors, they ensure steady pressure and uninterrupted lab or pilot operations.
