Calling all professionals working with hydrogen! WHA International is conducting a survey of hydrogen leak rates in piping and valve connections. The goal of the project is to identify real-world leak testing practices, data gaps, and opportunities to improve safety and standards for compressed gaseous hydrogen systems.

This survey is part of a broader research effort led by WHA International, funded by CSA Group and Natural Resources Canada.

Filling Gaps in H2 Industry Data

The goal of the project is to improve the safety of compressed hydrogen systems by addressing key data gaps related to hydrogen-specific leak rate information and leak testing standards. To support the development of more accurate risk models, testing practices, and codes and standards, we need real-world insight into how hydrogen systems are tested and perform today. 

This survey is designed to gather input from professionals across the hydrogen industry, including component manufacturers, system designers, users, certification bodies, and regulators with experience in hydrogen piping and valve connections. It asks about typical service conditions, leak testing methods, commonly used components, and known problem areas.

Advancing Hydrogen Safety Together

The results of this survey will help us:

• Identify which components and conditions are most associated with leaks
• Understand the range of leak testing practices currently in use
• Pinpoint where the biggest gaps in data, codes, and standards exist
• Recommend where future testing, standards development, and data collection should be focused

Your Input Matters: Take the Survey

The survey takes 10-15 minutes to complete and is open through May 30, 2025. Responses can be anonymous.
