Analysis of hydrogen mixing technology in terminal station of gas pipeline
Hydrogen energy is an important energy source for solving environmental pollution and resource scarcity problems,and the development of hydrogen energy has profound strategic significance.Using active natural gas pipelines for blending transportation of natural gas and hydrogen is an effective method to save construction investment and accelerate the promotion and utilization of hydrogen energy.Aiming at the issues of hydrogen embrittlement and gas stratification that are prone to occur in blending transportation of natural gas pipeline hydrogen,this article proposes the scheme of blending hydrogen at the end station of the gas pipeline,which coupled with the power grid and gas network,as well as the process measures of dynamic hydrogen blending and dual pressure level hydrogen blending.The above measures would accelerate the comprehensive utilization of natural gas and hydrogen energy.
