Problems solved by technology

[0004] The inventor found that most of the existing patents for the production, storage and utilization of hydrogen use hydrogen production equipment to generate hydrogen, and the research on hydrogen-containing pipeline transportation technology lacks an experimental platform and system, and it is impossible to realize the mixed transmission experiment of hydrogen and non-hydrogen gas. The air supply pressure and air supply volume cannot be adjusted according to the detection results at the transmission end

Description

technical field [0001] The present disclosure relates to the technical field of hydrogen energy utilization, in particular to a medium and low pressure hydrogen-containing pipeline experiment system and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Due to its wide range of sources, clean and low-carbon, high efficiency and flexibility, hydrogen plays a key role in promoting global energy transformation and realizing green and sustainable development. Hydrogen transportation is an important part of hydrogen energy utilization, and its long-distance transportation has attracted extensive attention. At present, hydrogen is mainly transported by high-pressure hydrogen cylinder long-tube trailers, liquid hydrogen tank trucks, and liquid hydrogen barges. However, these methods have high storage and transportation costs and low effic...
