Linde starts operating hydrogen separation plant

If commercialised, technology would allow hydrogen to be removed from blend with natural gas at high purity

Industrial gas supplier Linde has started up a pilot plant that separates hydrogen from natural gas streams. Hydrogen can be safely blended at volumes of up to 20pc in natural gas pipelines, and potentially at an even higher level if upgrades are made to infrastructure. Linde’s technology would enable this blended hydrogen to be removed in a pure form. “The Hiselect demonstration in Dormagen allows us to display essential technology for transporting hydrogen via natural gas pipelines in a real-life setting,” says John van der Velden, senior vice-president of global sales & technology at Linde Engineering. “It shows a way to leverage existing infrastructure. In doing so we avoid the high
