Challenges

High-pressure hydrogen storage with minimal footprint

As hydrogen adoption accelerates, especially in urban and space-constrained environments, the need for compact, high-pressure storage becomes critical. Steelhead’s composite overwrapped pressure vessels (COPVs) are engineered to deliver maximum volumetric efficiency, enabling high-density hydrogen storage in tight footprints—ideal for fueling stations, mobile units, and distributed energy systems.

Long-term safety and certification requirements

Hydrogen is a volatile gas that demands rigorous containment standards. Steelhead’s vessels are designed to meet or exceed global safety certifications including ASME BPVC, ISO 11119, PED and DOT standards. Our engineering prioritizes leak prevention, hydrogen embrittlement resistance, and fatigue performance to ensure long-term operational safety and regulatory compliance.

System modularity and transportability

Clean energy infrastructure often requires scalable, relocatable systems. Whether for temporary deployments, pilot projects, or remote installations, Steelhead’s modular vessel solutions are designed for easy integration, transport, and expansion—supporting the dynamic needs of hydrogen fueling networks and renewable energy hubs.
