DNM Moranbah Hydrogen Storage and Supply Concept Study

Applied Nano Technologies Pty Ltd (ANT) is exploring the technical and economic feasibility of producing “green” hydrogen (hydrogen production from renewable sources) to be used as a feedstock for ammonia production at the DNM facility. The proposed hydrogen production facility includes on-site solar power generation, electrolysers, storage and transport of the produced hydrogen to a DNM facility tie-in point.

ANT engaged GPA Engineering to perform a concept study, which included an options study, technical assessment and “Class 4” cost estimate. The physical boundaries of this study included:

  • Storage and transport of hydrogen gas from the electrolyser trains to the DNM tie-in point,
  • Transport of oxygen gas from the electrolyser trains to the DNM fence line,
  • Transport and storage of the demineralised water from the DNM tie-in point to the electrolyser trains.

Four options for hydrogen gas storage and transport were considered, which were reviewed against technical and economic criteria. These options were:

  • Medium pressure storage at the electrolyser trains and a high-pressure storage and delivery system.
  • Metal hydride storage at the electrolyser trains and high-pressure storage and delivery system.
  • Low-pressure buffer storage at the electrolyser train header and high-pressure storage and delivery system.
  • Variable inlet compression control with DNM bypass supply and high-pressure storage and delivery system.

The desktop study included a design basis for each of the three systems, identification of hydrogen storage and transport options, review the four developed options refining to a single preferred option. Complete a concept level design for the facility for the recommended option including risks and further work, and prepare a factored +40/-30% cost estimate of the preferred option.

GPA was engaged by Applied Nano Technologies Pty Ltd (ANT) to perform a concept study for a proposed hydrogen production facility. The facility was to produce hydrogen from renewable sources.
