Hydrogen on tap

Linde and Evonik Industries team up to offer a mature, fully integrated solution delivering hydrogen via the natural gas pipeline

  • Accelerating the transition to a low-carbon economy
  • Synergized, ready-to-run H2 separation solution for universal deployment
  • Superior gas selectivity and cost efficiency

HISELECT® powered by Evonik has the potential to help decarbonize hard-to-abate sectors like iron and steel, chemicals, oil refining and heavy transport (trucks, ships, trains and aircraft) to speed the transition to a low- or zero-carbon economy.

Using hydrogen to buffer renewable energy

Hydrogen (H2) has the potential to play a key role in connecting different infrastructure layers in a low- or zero-carbon economy. Looking beyond its conventional applications as an industry feedstock in refining and fertilizer production, it is increasingly being heralded as a way to unlock the potential of renewable energy. In simple terms, surplus solar and wind energy can be converted to hydrogen and then to electricity on demand. Or it can be used to power zero-emissions fuel-cell cars and advance electromobility. The question is, how can hydrogen gas be efficiently delivered to the point of use? To date, the market has been deterred by the high costs that would be involved in building a dedicated hydrogen pipeline or delivery infrastructure.

HISELECT® powered by Evonik combined with PSA for 99.9999% H2

The good news is: the infrastructure is already in place! H2 can be simply injected into the existing natural gas pipeline and delivered to a wide range of end-point applications. The separation and purification technologies required downstream to extract hydrogen from the pipeline or natural gas blend are already available.

This delivery solution combines our market-leading pressure swing adsorption (PSA) technologies with a custom-designed membrane/permeation technology developed in collaboration with Evonik Industries. Made from hollow fiber, the HISELECT® membranes separate a stream of hydrogen at a concentration of up to 90 percent. Our proven PSA technologies then increase the purity to above 99.9999 percent.

This innovative, ready-to-use concept will be demonstrated at our Dormagen real-scale plant near Düsseldorf in Germany, due to go on stream in 2021.

Ready-to-run solution for highly efficient extraction of H2 from natural gas pipeline blend.

Hybrid solution combining PSA & HISELECT® powered by Evonik for hydrogen

Innovative combination of pressure swing adsorption (PSA) plus HISELECT® membranes provides a cost-effective, ready-to-run solution for extracting H2 from natural gas pipelines.

HISELECT® powered by Evonik

Thanks to their excellent selectivity, HISELECT® for hydrogen membranes enable hydrogen to be extracted from natural gas blends at concentrations of up to 90%. With the first real-scale demo showcase under construction and the first reference customer already up and running, HISELECT® for hydrogen synergizes the innovative strengths of Linde and Evonik Industries.

Hybrid solution with downstream PSA

HISELECT® for hydrogen can be combined with a pressure swing adsorption unit from Linde to achieve benchmark H2 recovery rates in excess of 99.9999%. Having already engineered over 900 adsorption plants worldwide, including more than 500 H2 PSA plants, Linde builds on over 40 years of proven experience in adsorption technologies to deliver the world’s highest capacities and on-stream availability levels.
