RP1.4-04 Hydrogen gas specification and review of end-user instrumentation

Executive Summary

This project developed specifications for hydrogen to be used in Australia. It also included a review and assessment of the impacts of adding hydrogen to natural gas, or using 100% hydrogen, on instrumentation used by industrial and commercial end users. The review gathered information from suppliers, industry experts and literature on the influence of hydrogen on end-user instrumentation and safety equipment.

Outcomes / Impact

Through this project, industry will gain an understanding of the benefits of separate supplies to different end-users and purification options. They will also gain an understanding of suitability of instruments, potential use of oxygen, and the performance of heat pumps.

Those producing and injecting hydrogen into gas networks will have a specification to use. Researchers using hydrogen will have guidance on agreed specifications to use in laboratories and for modelling studies.

Network and pipeline operators, as well as end-users receiving up to 10 vol% hydrogen in natural gas or 100% hydrogen will know if their instruments need to be adjusted or changed.

FFCRC participants will be able to use new knowledge of the installed COP of heat pumps as a function of ambient temperature to compare costs of upgrading electricity networks to supply expanded heat pump use, with using blended hydrogen and natural gas, or 100% hydrogen. (This comparison might be the subject of a subsequent proposal).
