APA completes successful hydrogen testing in gas pipe

APA Group, a leading Australian energy infrastructure company, on May 19 announced the successful completion of laboratory testing to assess the feasibility of converting a gas transmission pipeline into a pure hydrogen service.

The testing, conducted on a 43-km section of the Parmelia gas pipeline in Western Australia, confirmed that the pipeline materials can safely transport up to 100% hydrogen without reducing the operating pressure.

The successful testing was carried out at the University of Wollongong's dedicated hydrogen laboratory in collaboration with the Future Fuels Cooperative Research Centre. The knowledge gained from the Parmelia Gas Pipeline conversion project will also contribute to the establishment of Australian standards for hydrogen pipelines, APA said.

APA CEO Adam Watson said this was an exciting milestone in Australia’s energy transition and the country’s move closer to hydrogen becoming a core part of the future energy mix, particularly for industrial customers.

“This research is very encouraging as it suggests there could be potential for our existing gas transmission pipeline network to play an important role in connecting hydrogen production hubs to industrial sites across the nation,” Watson said.

The project will now progress to the next phase, which involves detailed safety studies, conversion plans, and exploring supply and offtake opportunities. APA said its extensive pipeline network, spanning 15,000 km, is strategically positioned near areas suitable for hydrogen production.
