CTOnews.com November 23 news, According to CCTV news report, November 20, The state pipe network announced, The first full size hydrogen-doped natural gas pipeline closed space leakage explosion test successfully implemented.

▲ Source CCTV News This experiment selects 323.9 mm diameter pipeline, with the maximum hydrogen doping ratio of 30%, which is the largest scale pipeline hydrogen-doped natural gas explosion test in China.

According to reports, the so-called natural gas pipeline hydrogen transmission, in fact, hydrogen and natural gas in different proportions mixed, and then use the existing natural gas pipeline network for transmission. The hydrogen-doped natural gas can be used directly, or hydrogen and natural gas can be separated and used separately.

According to the report, the proportion of natural gas adulteration utilization at present in China is 3%, and the highest proportion of natural gas adulteration transportation in some European and American countries has reached 20%, which is enough to show that the achievement is of great significance, filling the blank of hydrogen adulteration explosion verification test of long-distance natural gas pipeline in China and laying a foundation for realizing independent control of hydrogen adulteration transportation technology of long-distance natural gas pipeline.

CTOnews.com inquires that China is the world's largest hydrogen producer and has great potential in hydrogen supply. Up to now, the number of domestic hydrogen refueling stations ranks first in the world, and domestic long-distance hydrogen transmission pipelines are under planning and construction. In addition, a number of central enterprises have laid out the whole industrial chain of hydrogen production, hydrogen storage, hydrogenation and hydrogen use.
