Hydrogen Delivery for Decarbonization: Evonik’s HISELECT Paved Way

Here’s a post from Linde Engineering that includes the following:

  • HISELECT® powered by Evonik: A game-changer for decarbonizing hard-to-abate sectors like iron and steel, chemicals, oil refining, and heavy transport.
  • Hydrogen’s potential in a low- or zero-carbon economy: Connecting different infrastructure layers and unlocking the potential of renewable energy.
  • Efficient hydrogen delivery: HISELECT® for hydrogen membranes enable hydrogen extraction from natural gas blends at up to 90% concentration.

Here’s the brief explanation:

Evonik’s HISELECT technology, powered by their collaboration with Linde Engineering, plays a pivotal role in the modern approach to hydrogen delivery. The technology is employed at the world’s first full-scale pilot plant in Dormagen, Germany, to extract hydrogen from natural gas pipelines using a membrane technology developed by Evonik. This plant represents a significant step forward in making the hydrogen delivery process more efficient and cost-effective​

The HISELECT technology incorporates high-performance membranes capable of separating hydrogen from natural gas streams with up to 90% initial concentration. These membranes are then paired with Linde’s advanced pressure swing adsorption (PSA) technologies to achieve hydrogen purity levels exceeding 99.9999%. This integration of technologies facilitates the extraction and purification of hydrogen directly from existing natural gas pipelines, making it a highly efficient solution for hydrogen transport​.

This innovative system not only supports the decarbonization of various hard-to-abate sectors by providing a cleaner energy source but also leverages existing gas infrastructure, which reduces the need for new pipeline construction. The HISELECT membranes offer robust performance and are particularly noted for their high selectivity and chemical resistance, which are crucial for maintaining operational efficiency under harsh conditions​.

Furthermore, the integration of this technology is aimed at supporting the development of a European Hydrogen Backbone, envisioning a vast network of hydrogen pipelines by 2040, a substantial portion of which could be converted from existing natural gas pipelines. This vision underscores the strategic role of HISELECT in transitioning to a more sustainable hydrogen-based energy system across Europe​.

Overall, the collaborative efforts between Evonik and Linde in developing HISELECT technology mark a significant advancement in the use of existing infrastructure for clean hydrogen delivery, aligning with broader goals of energy sustainability and carbon reduction.

Here are three interesting questions that could be explored:

  1. How does the HISELECT® membrane technology, combined with pressure swing adsorption (PSA), enable hydrogen extraction from natural gas pipelines at such high purity levels (99.9999%)?
  2. Considering the potential of hydrogen to buffer surplus renewable energy, how could this technology impact the scalability and economic feasibility of hydrogen as a storage medium for renewable energy sources like solar and wind?
  3. What are the specific challenges or limitations associated with integrating the HISELECT® technology into existing natural gas infrastructure, and how does this approach compare to other hydrogen delivery methods in terms of cost-efficiency and environmental impact?
