“…66 To meet the same energy demand, Huang et al 67 believed that increasing the transmission pressure can meet the requirements for gas transmission power. Wang et al 68 used HYSYS software to build a model. When the hydrogen ratio is 30% at 15 °C, the pipeline outlet pressure increases by 9.1%, the gas transmission volume increases by 14.8%, and the gas transmission power decreases by 9.2%.…”

“…The compressor is the main piece of equipment providing pressure for the natural gas pipeline. Wang et al 68 found that when the compressor’s fixed speed remains unchanged, compared with the pure natural gas working condition, when the hydrogen mixing ratio is 30%, the compression ratio decreases by 20%, and the shaft power decreases by 36%. For this problem, Haeseldonckx et al 66 believed that the transmission pressure can be increased by properly increasing the compressor speed, but most natural gas compressors currently in service do not consider the impact on the blade material under various conditions of hydrogen compression.…”

Thanks to the advantages of cleanliness, high efficiency, extensive sources, and renewable energy, hydrogen energy has gradually become the focus of energy development in the world's major economies. At present, the natural gas transportation pipeline network is relatively complete, while hydrogen transportation technology faces many challenges, such as the lack of technical specifications, high safety risks, and high investment costs, which are the key factors that hinder the development of hydrogen pipeline transportation. This paper provides a comprehensive overview and summary of the current status and development prospects of pure hydrogen and hydrogen-mixed natural gas pipeline transportation. Analysts believe that basic studies and case studies for hydrogen infrastructure transformation and system optimization have received extensive attention, and related technical studies are mainly focused on pipeline transportation processes, pipe evaluation, and safe operation guarantees. There are still technical challenges in hydrogenmixed natural gas pipelines in terms of the doping ratio and hydrogen separation and purification. To promote the industrial application of hydrogen energy, it is necessary to develop more efficient, low-cost, and low-energy-consumption hydrogen storage materials.

“…Natural gas produces (50 to 60) % less CO2 when burnt than coal and (15 to 20) % less heattrapping gases than gasoline when used in vehicles [1,2], making it central to the transition towards a low carbon-emissions society [3][4][5][6][7]. Prior to being fed into pipeline systems or liquefaction facilities [8], raw natural gas needs to be processed for it to meet product specifications. This involves the separation of a series of undesirable components, like carbon dioxide, water, and hydrogen sulfide, and/or the recovery of more valuable components, for example, ethane, propane, butane, heavier hydrocarbons and helium [9][10][11][12][13][14].…”
