Hydrogen Flow Rig

The Hydrogen Flow Cell is being designed to combine with a Hiden HPR20 mass spectrometer designed to characterise the bulk flow properties of hydrogen through a 1m long sandstone core at elevated temperature and pressure.

Breakthrough curves can be used to determine: advective velocity; mechanical dispersion; molecular diffusion and sorption of hydrogen during mass transfer through porous reservoir sandstones.

The Hydrogen Flow Rig has been designed  to provide:

  • 1m long, 38mm diameter fell sandstone core contained within gas tight foil, resin and stainless steel piping.
  • Up to 1MPa gas pressure.
  • Up to 60oC rock temperature.
  • Up to 60oC injection gas temperature.
  • Single and multiphase gas flow including hydrogen, nitrogen, noble gasses, SF6 tracer and CO2.
  • Flow rates from 0.01ml/min to 10ml/min.
  • Upstream, downstream and differential pressure measurement and logging.
  • Gas sampling by Hiden HPR20 mass spectrometer.


The hydrogen rig is not currently functional as awaiting key components.


The team within the Applied Geoscience Laboratory welcomes scientific collaboration and are always happy to discuss new projects and experimental designs.  Please contact:
