Methane is a significant contributor to anthropogenic greenhouse gas emissions. Blending hydrogen with natural in existing networks presents promising strategy reduce these emissions and support the transition carbon-neutral energy system. However, hydrogen’s potential for atmospheric release raises safety environmental concerns, necessitating an assessment of its impact on methane leakage behavior. This study introduces methodology estimating how fugitive change when network shifted 10% blend by combining analytical flowrate models data from sampled leaks across network. The involves developing conversion factors based emission rates predict corresponding different sections network, including mainlines, service lines, facilities. Our findings reveal that while overall volumetric increase 5.67% mainlines 3.04% primarily due lower density, decrease 5.95% 8.28% lines. considering Global Warming Potential, net reduction 5.37% 7.72% work bridges gap between research readiness, which traditionally focuses safety, sustainability studies emission.
