German firm Siqens has proved its hydrogen separation technology at CSIRO’s Hydrogen Technology Demonstration Facility (HTDF) in Victoria, Australia.
The findings could support efforts to separate helium and naturally occurring hydrogen, also known as geological or white hydrogen.
Both gases are often found together and need to be separated using specialist technology for hydrogen to be used as a fuel. For this project, Siqens used CSIRO’s test facility to demonstrate its electrochemical hydrogen separation rig.
The team mimicked the separation of a naturally occurring concentration by feeding hydrogen–helium mixtures ranging from 10% to 75% into the rig.
