Hydrogen storage
Type-IV high-pressure vessels for hydrogen, CNG, and biogas storage — type-approved per EN 12245, ADR, and TPED.
The product
High-pressure vessels engineered for hydrogen storage parks
Gaznet supplies type-IV high-pressure vessels for hydrogen, CNG, and biogas storage. Each vessel uses a plastic liner with stainless steel end bosses and a composite outer wrap of high-strength, lightweight fibreglass and epoxy resin. The construction delivers the highest safety levels for high-pressure storage and transport of large hydrogen volumes — at a competitive price per kg of hydrogen stored.
Vessels are type-approved per EN 12245, ADR, and TPED. Compared to steel skids of equivalent capacity, type-IV pressure vessels deliver up to 70% weight reduction.

Why fibreglass over steel or carbon fibre
Fibreglass pressure vessels combine non-corrosive properties (no galvanic oxidisation risk), excellent fatigue durability, wide temperature tolerance, long design life, and enhanced safety. Together those properties consistently challenge — and beat — steel and carbon-fibre alternatives on lifecycle cost.
Built for ADR transport
Our CNG and biomethane transport containers are fully ADR-compliant and built to the Pressure Equipment Directive. Even in the harshest conditions — salt, moisture, extreme weather — the vessels keep their certified safety margin. Minimal maintenance, decades of service.
