    • A method and system for storing and supplying hydrogen to a hydrogen pipeline in which a compressed hydrogen feed stream is introduced into a salt cavern for storage and a stored hydrogen stream is retrieved from the salt cavern and reintroduced into the hydrogen pipeline. A minimum quantity of stored hydrogen is maintained in the salt cavern to produce a stagnant layer having a carbon dioxide content along the cavern wall and the top of a residual brine layer located within the salt cavern. The compressed hydrogen feed stream is introduced into the salt cavern and the stored hydrogen stream is withdrawn without disturbing the stagnant layer to prevent carbon dioxide contamination from being drawn into the stored hydrogen stream being reintroduced into the hydrogen pipeline.
    • 本发明涉及一种用于储存和供应氢气至氢气管道的方法和系统,其中将压缩的氢气进料流引入盐穴中以供储存,并且储存的氢气流从盐穴中回收并重新引入到氢气管道中。 储存的氢气的最小量保持在盐穴中,以产生沿着洞穴壁和位于盐穴内的残留盐水层的顶部具有二氧化碳含量的停滞层。 压缩的氢气进料流被引入盐穴中,并且储存的氢气流被取出而不干扰滞流层以防止二氧化碳污染物被吸入储存的氢气流中,该氢气流被重新引入到氢气管道中。
