Techno-economic study on carbon negative biohydrogen potential in Australia to tackle climate change

Techno-economic study on carbon negative biohydrogen potential in Australia to tackle climate change

Project Outline (up to 200 words):

Hydrogen is a versatile energy carrier and a feedstock chemical with applications across energy and industrial sectors. Countries like Japan and South Korea have started transitioning towards a Hydrogen Economy to enable carbon neutral energy utilisation. Australia is also following their footsteps with projects like the Hydrogen Energy Supply Chain (HESC) in the Latrobe Valley.

While the HESC project will produce carbon neutral hydrogen from brown coal via underground CO2 sequestration, the aim of this project is to investigate carbon negative biohydrogen production. This will be achieved by utilisation of non-food biomass as a feed and sequestering the waste CO2. The hydrogen produced can be used to supplement the gas grid, to generate power or for export. This desktop study will be of interest to the energy and chemical industries and project partners of the HESC project.

Scope of the project includes:

  • Literature review and selection of the main processes, biomass resources and CO2 sequestration sites;
  • Development of the technical model/s for biohydrogen production and CO2 sequestration;
  • Simulation of the model/s;
  • Techno-economic assessment for nation-wide carbon negative biohydrogen production; and
  • Recommendations based on the results.

Resources: Simulation software (e.g., ASPEN, gPROMS or COCO-ChemSep)
