Jemena’s report describes the testing plan that was developed to determine the performance of this hydrogen project, and the results achieved from that testing.
Report extract
The accuracy of the hydrogen injection system was tested by injecting a known amount of hydrogen at the WSGHH facility and collecting a sample of the downstream blend at four locations to determine how well the gases were mixed. The results of the test demonstrated that the downstream gas compositions contained had a hydrogen blend that deviated from the amount injected at the facility by up to 9 %, which was within the acceptable range of ±10 %. Additionally, to comply with Australian Standards, the Wobbe Index of the natural gas and hydrogen blend was measured and estimated for future blends of up to 10 %, which demonstrated that gas from the facility should remain well within the acceptable limits within the scope of the program.
