Linde Engineering’s plans to extract hydrogen from natural gas pipelines
According to Linde Engineering, membrane technologies are vital to efforts around the globe for establishing hydrogen infrastructure. In Europe, 11 transmission system operators are working on creating the European Hydrogen Backbone.
Linde Engineering has officially started up the world’s first full-scale pilot plant in Dormagen to showcase how hydrogen can be separated from natural gas streams. This is made possible by means of to the patented HISELECT powered by Evonik membrane technology. The process is a key enabler for scenarios in which hydrogen is blended with natural gas and transported via natural gas pipelines. The blended gas could consist of between 5 and 60 percent hydrogen. Membranes are then used to extract hydrogen from these natural gas streams at the point of consumption. The resulting hydrogen has a concentration level of up to 90 percent. When further processed with Linde Engineering’s pressure swing adsorption (PSA) technology, a purity of up to 99.9999 percent can be achieved.
Linde Engineering on hydrogen extraction: the HISELECT demonstration
«The HISELECT demonstration in Dormagen allows us to display essential technology for transporting hydrogen via natural gas pipelines in a real-life setting. It shows a way to leverage existing infrastructure. In doing so we avoid the high costs and the long process that would be involved in building a dedicated hydrogen pipeline infrastructure», said John van der Velden, Senior Vice President Global Sales & Technology at Linde Engineering.

According to Linde Engineering, membrane technologies are vital to efforts around the globe for establishing hydrogen infrastructure. In Europe, 11 transmission system operators are working on creating the European Hydrogen Backbone. Their aim is to build and expand a functional hydrogen network, based largely on repurposed existing natural gas infrastructure. Membrane technology like HISELECT could be integral for efficiently transporting hydrogen to end users for use as an industry feedstock, as a source of heat and power, or as a transportation fuel.
