Summary of Project

“Hydrogen has different characteristics compared to natural gas which means that it interacts with pipeline materials differently. When the gases are mixed or if hydrogen is transmitted as the sole gas, the effects on pipeline infrastructure need to be considered to minimise leakage, ensuring safe transmission and reduced economic impact of losses. RD&D opportunities Understand network and pipeline effects from hydrogen and hydrogen mixes on distribution and transmission pipelines to support site-by-site injection trials and long-term use. This includes understanding steel pipeline and component part material performance, how pipeline characteristics vary by location and geography, and any associated replacement or augmentation considerations due to embrittlement or cracking risks. Develop methods and identify suitable (or novel) materials and components to support network operations. For example, more efficient seals and pipe joints to minimise leakage or lower costs. This may come through scale-up and RD&D in manufacturing methods. Test or develop gas meters and sensors to accurately measure hydrogen flow rates and volumes and support different concentrations of hydrogen blending and injection (including accounting for distribution pressures and natural gas requirements to balance differences in heating values). These sensors could also be leveraged to provide data on network health and maintenance. Test or further develop specialised technologies and sensors (where needed) for injection and separation. For example, technologies to support the separation of hydrogen from blended gas for different residential, commercial and industrial customers.”
