China successfully conducted its first high-pressure pure hydrogen pipeline test at a testing ground of China Oil & Gas Pipeline Network Corp in Xinjiang Uygur autonomous region in northwestern China on Sunday.

This achievement provides technical support for future large-scale, low-cost and long-distance pure hydrogen transportation in the country, said the company, also known as PipeChina, the country's largest energy infrastructure owner.

Currently, trucking is still the mainstay long-distance hydrogen transport method, which is costly and inefficient.

Domestic energy companies have been laying out plans to build long-distance hydrogen pipelines in the country to meet the growing hydrogen demand in the transport sector and accelerate green energy development in the country.
