Project summary description:
In recent years, blending hydrogen into the existing natural gas pipeline is adopted as a means of increasing the output of renewable energy systems. The addition of clean hydrogen into the natural gas network is included in Australia’s long-term emissions reduction plan and can contribute towards Australia’s plan to reach net zero by 2050. Australia will rely on gas energy for many years to come, which makes existing pipeline infrastructure a positive and important investment. The safety of these natural gas pipelines is important. These safety issues become more important with the addition of hydrogen due to widening of flammability limits and increase in flame speed. It is therefore necessary to assess the vulnerability of built pipelines to the external interferences and develop adequate protections.
