ISO 19881:2025

Gaseous hydrogen — Land vehicle fuel containers Published (Edition 2, 2025)

What is ISO 19881?

ISO 19881 sets performance-based requirements for compressed hydrogen fuel containers used in land vehicles. It covers everything from design and materials to manufacturing, testing and marking — ensuring that hydrogen containers are safe, durable and reliable across a range of operating conditions. This standard supports the development of hydrogen-powered vehicles by establishing a unified global baseline for fuel container quality.

Why is ISO 19881 important?

Hydrogen is a growing solution for zero-emission mobility, but its safe use depends on the quality of components like fuel containers. ISO 19881 helps manufacturers produce containers that meet strict safety and performance criteria, while also aligning with international frameworks like UN GTR 13. It promotes global harmonisation, allowing manufacturers to streamline development and reach multiple markets with a single, compliant design.
