Linde Engineering Starts Up World’s First Plant for Extracting Hydrogen from Natural Gas Pipelines Using Membrane Technology

Petrochemical industry | 22 Jan 2022 IST | Polymerupdate.com
• The full-scale plant at Linde production site in Dormagen, Germany, features Linde’s HISELECT® powered by Evonik membrane technology to extract hydrogen from natural gas pipelines.
• As an accelerator, the facility contributes to a low-carbon economy and paves the way for transporting hydrogen in natural gas pipelines.
• When coupled with pressure swing adsorption technology, Linde’s HISELECT® powered by Evonik has the potential to help decarbonize hard-to-abate sectors.

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 using Linde’s 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.

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.

“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,” says John van der Velden, Senior Vice President Global Sales & Technology, Linde Engineering.

Linde covers every part of the hydrogen value chain, from source to service. Regardless of whether customers want to use hydrogen as a zero-emissions source of fuel, a feedstock gas for industry or a source of heat and power for buildings – Linde has the technologies and expertise to support every project.

About Linde HISELECT® powered by Evonik membrane technology

The high-performance membrane package unit is based on a robust polymer developed by Evonik. It consists of highly selective hollow fibres that efficiently separate the hydrogen in the blended natural gas stream from the main components of methane and higher hydrocarbons. The membrane material is particularly robust, as natural gas contains a host of other substances that can influence the separation performance of membranes.
