Hydrogen storage tanks

A designer’s guide to US-made stainless steel

The construction of large numbers of storage tanks is vital to support the growth of the US hydrogen economy. This presents two distinct challenges for materials: strength and durability at low temperatures to hold liquid hydrogen; resistance to hydrogen embrittlement to store gas at high pressure.

This guide for tank designers outlines the background to these challenges, and why they can have confidence that they’ve selected the right material for their project by specifying austenitic stainless steel, melted and poured in the US at Outokumpu’s Calvert Mill in Alabama.

The designer’s guide covers the following topics:

  • Why storage is vital to support the developing US hydrogen industry
  • Storage tanks – why stainless steel outperforms carbon steel
  • What is austenitic stainless steel?
  • Introduction to America’s most technically advanced stainless steel mill and stainless steel grades produced for hydrogen storage
  • Materials challenges posed by hydrogen storage, including ductility at low temperatures and resistance to hydrogen embrittlement
  • Switching to stainless steel – addressing fabrication myths and demonstrating ease of use with existing equipment
  • A new high-performance stainless steel that extends the possibilities for hydrogen storage — combining cost-efficiency with enhanced temperature resistance
  • Stainless steel applications beyond tank storage
  • Frequently asked questions and answers

Download the guide to gain practical insights and technical guidance that can help you make the right material choices for your hydrogen storage designs—both for today’s needs and tomorrow’s demands.
