Standards for hydrogen delivery and storage

71%

of Canada’s natural gas distribution pipelines

are made of polyethylene, which can resist exposure to hydrogen^[1]

Cooled to -253⁰C,

liquefied hydrogen

can be transported by road in steel tube trailers^[2]

Salt caverns

are the most common method

for underground storage of hydrogen^[2]

Hydrogen delivery and storage

Learn how CSA Group’s research identifies key topics for the evaluation of pipeline materials for hydrogen service.

Standards support safe and reliable hydrogen delivery and storage

Hydrogen, a carbon-free energy carrier, can play a critical role in Canada’s net-zero future. CSA Group is engaged in multiple research and standards development initiatives across the hydrogen ecosystem, including hydrogen delivery and storage.

As demand for hydrogen grows, it is important to support its safe delivery and storage from the point of production to end use. CSA Group helps address this challenge by leveraging a comprehensive portfolio of standards for delivery and storage of hydrocarbons and transportation of dangerous goods. Informed by extensive research, these standards are being enhanced and updated to incorporate guidance and considerations specifically related to hydrogen, including its impacts on the associated infrastructure, equipment and materials.

CSA Group research and standards for hydrogen delivery and storage provide guidance and requirements for:

hydrogen delivery, transmission, and distribution via pipelines, road, and rail
above and underground hydrogen storage

To learn about CSA Group standards solutions across the hydrogen ecosystem, see also Standards for hydrogen production and Standards for hydrogen vehicles and fuel cell technologies.

Feature

Oil and gas pipeline systems

The 2023 edition of CSA Z662 incorporates several important updates, including a new clause on hydrogen and hydrogen blend pipeline systems and revisions throughout the standard to address unique design, material, construction, and operational considerations for pipelines containing hydrogen.
