In this paper the effects of hydrogen on transport natural gas-hydrogen mixture in a high-pressure gas transmission system are investigated detail. Our research focuses decrease transferable energy content under identical operating conditions as is blended network. Based extensive literature review outstanding challenges and key questions using introduced. our transmissible factor - TEF defined that quantifies relative capacity pipeline caused by blending. A new equation proposed to find value at specific pressure temperature for different concentrations. This practical helps operators decision-making process when emerges system. change compression power requirement, which increases significantly with blending,
