Development of a bubble reactor for hydrogen production via methane pyrolysis in molten medium 

Project description 

Turquoise hydrogen is produced from natural gas pyrolysis in molten metals or salts at high temperature, co-producing black carbons for carbon storage or other uses. Utilising renewable thermal energy to drive the pyrolysis process can further reduce the carbon intensity of hydrogen production. In this project, UoA and the industrial partner 1414D work through a CRC-P (round 15) project to develop a new fluid reactor based on the SiPHyR technique, which integrates licensed designs from the UoA with 1414 Degrees’ silicon based thermal energy storage technology, SiBrick®, to enable continuous hydrogen production from intermittent renewable electricity. The PhD student(s) will join the project to conduct experimental and/or numerical studies related to the reactor development and process optimisation under supervisions of senior researchers from UoA and 1414D.

Research objectives

1. To systematically measure isothermal flow conditions relevant to bubble reactors using optical diagnostic methods, followed by image processing, which may include machine learning-based techniques.
2. To analyse bubble dynamics from the experimental results, including bubble formation, rising velocity, residence time, coalescence, and de-gassing, to provide valuable insights for bubble reactor design.
3. Numerical simulations may also be conducted to assess the reliability of existing modeling tools by comparing them with experimental results.
4. The objectives of this industry PhD program also include an internship at the industry partner site to join experiments and characterization of carbon particles collected from a reactor.

Eligibility criteria 

This opportunity is open to Australian citizens, permanent residents and international students who meet the requirements for PhD admission at the University of Adelaide, and who can demonstrate suitable experience in a related field (through a high quality Honours or Masters degree). The successful candidate must be able to enrol as a full-time PhD student at the University in the year of the offer. They must remain based in Adelaide, South Australia for the duration of the award.

Stipend

The University of Adelaide Research Scholarship will be paid for 3.75 years at a stipend rate of $35,300 per annum (indexed annually). It is likely to be tax exempt, subject to Taxation Office approval. International students will receive single overseas student health cover for the duration of candidature, and a relocation allowance (if applicable). Details of terms and benefits will be provided to the successful candidate in their Conditions of Award.
