Siqens Introduces Groundbreaking Hydrogen Separation Technology to Revolutionize Energy Networks and Enhance Gas Infrastructure Efficiency

The presentation at Siqens highlights a novel electrochemical hydrogen separation (EHS) technology designed to decarbonize the economy by efficiently delivering hydrogen through existing gas networks. Initially centered on methanol fuel cells, Siqens has expanded its expertise in electrochemistry over ten years to develop EHS for extracting hydrogen from various feed gases. This approach supports centralized green hydrogen production and decentralized distribution using infrastructure like Germany's extensive 540,000-kilometer gas network, which is largely prepared for integrating hydrogen. The system allows high-purity de-blending of hydrogen suitable for applications such as fuel cells or recycling processes in industries with significant off-gas emissions. Successful demonstrations have been conducted in Melbourne and Bavaria where EHS purifies helium and extracts high-quality fuel cell-grade hydrogen respectively. Economically viable due to low energy requirements compared to traditional methods, this solution also addresses environmental concerns by replacing diesel generators at telecom towers with cleaner alternatives powered by methanol fuel cells—a core business area for Siqens. This technology focuses on separating and purifying hydrogen from gas mixtures while redirecting other gases back into the network; it can handle chemical off-gases with up to 50% high concentrations of Hydrogen ensuring only nitrogen is released post-separation into the atmosphere Current costs range between 2-3 euros per kilogram of extracted Hydrogen due minimal energy expenses including capital expenditure Despite lacking pure pipelines yet future systems will still require purification technologies because transported tends become impure distances making their indispensable against stranded assets Their support compressing low-pressure distribution networks higher pressures around bars plans further increases When integrating natural regulated government policies they aim blend reach concentration without compromising safety standards efficiency terms British Thermal Units BTUs compared usage.

Talk of session: Hydrogen and its Last Mile - How to Close the Ultimate Gap?

The production of hydrogen from renewable energy sources (RES) has made significant progress, with projects of various scales becoming a reality. However, the challenge of efficiently delivering hydrogen to end users remains, and multiple pathways are explored.Despite being the simplest molecule, hydrogen's delivery methods are not yet standardized. This session will delve into the practical considerations of different hydrogen distribution solutions across diverse project settings.
