Munich, July 2025: German clean energy innovator Siqens GmbH has successfully demonstrated its cutting-edge Electrochemical Hydrogen Separation (EHS) technology at CSIRO’s Hydrogen Technology Demonstration Facility in Victoria, Australia.
The demo-trial processed hydrogen–helium gas blends and achieved up to 4.7 kg/day of fuel-cell-grade hydrogen, using a novel membrane that selectively separates hydrogen with high efficiency and low energy use. This breakthrough results in separating hydrogen from helium supports furthermore the viability of geological (“white”) hydrogen — a potentially game-changing, low-cost resource for future clean energy supply.
It has the potential to significantly reduce hydrogen production costs—estimated geological hydrogen cost around $2.30/kg, versus conventional methods exceeding $6/kg.
With strong interest from over 25 industry and government organizations, Siqens is now looking at partnerships for commercial deployment across Australia.
“Our technology offers a scalable, cost-effective pathway for pure hydrogen production, unlocking new supply chains and energy opportunities,” said Siqens CEO Dr. Thomas Klaue.
