In a new Tech Talk video produced in collaboration with Hyfindr, a leading hydrogen technology platform, Tenaris provides a technical overview of the design, maintenance and long-term performance of steel vessels for hydrogen storage.
The episode examines key factors that influence vessel lifespan, including fatigue, hydrogen embrittlement and inspection cycles. It also explores how microscopic hydrogen interactions and cyclic pressure variations affect steel performance, while outlining strategies to optimize operating conditions and extend service life.
“Steel vessels for hydrogen storage undergo thousands of charge and discharge cycles over their lifetime,” said Maurizio Bellingardi, Tenaris Senior Product Manager for Hydrogen Technology Industrial Applications. “Understanding how fatigue develops and how hydrogen interacts with steel helps operators extend vessel life and reduce downtime. Hydrogen can reduce steel’s ductility and toughness, but engineers know how to design safe, practical solutions by selecting the right materials, environments and engineering conditions. That’s where the research and testing efforts of manufacturers are crucial.”
As hydrogen storage becomes increasingly important in energy and mobility applications, Tenaris leverages its metallurgical expertise and seamless manufacturing capabilities to deliver safe, efficient and durable storage solutions. In 2021, the company introduced THera®, its proprietary technology offering high-strength, reliable materials designed specifically for hydrogen storage and transport.
The THera® hydrogen storage system is designed for modularity, scalability and high-pressure durability, allowing operators to expand capacity by adding identical vessels without redesigning existing infrastructure.
The Tech Talk video is part of Tenaris’s broader effort to share technical knowledge and best practices across the hydrogen value chain, helping industry stakeholders optimize performance and safety in hydrogen storage and transport.
