About this scholarship
Description/Applicant information

Hydrogen energy appears to play an important role in energy transition as an energy carrier in Australia. Moreover, Australia has great opportunities from hydrogen export given its geographical and natural resources’ strengths. Australia could export over three million tons hydrogen to meet the global hydrogen demand by 2040, worth up to $10 billion each year to the economy by that time.
However, the volumetric inferior calorific values in kWh/m3 of hydrogen is the lowest (530kWh/m3) compared with other fuels although its energy density is the highest in mass (33.3 kWh/kg). Therefore, hydrogen storage particularly the scalable, large-scale and long-term storage system is becoming the centre of attention to underpin the hydrogen economy supply chain in Australia.
In this context, large-scale hydrogen storage in porous media has been proposed for example in existing salt caverns, depleted oil and gas reservoirs and saline aquifers. Compared to surface hydrogen storage, underground hydrogen storage has benefits of safety brought by the solid caprock sealing, huge storage space, lower cost than surface tanks, high availability in existing underground storage sites. However, given that salt caverns may not be widely available for hydrogen storage in Australia in particular along the coastal line, saline aquifers and depleted hydrocarbon reservoirs in particular gas reservoirs have been widely considered for large-scale and long-term hydrogen storage.
While the expectations on large-scale hydrogen storage in porous media is high, the feasibility and potential risks remain untested and unquantified. In particular, few research have been carried out to understand the impact of hydrogen-brine-rock interactions on hydrogen conversion and contamination, and fewer have looked beyond these processes on storage integrity. This presents tremendous impediments to manage and predict the large-scale hydrogen storage in porous media. In this context, this project aims to reveal the controlling factor(s) behind the hydrogen conversion and contamination due to the geochemical reactions, and its implications on fracture mechanics which is a fundamental to storage integrity. To achieve the objectives, a combination of multi-scale experimental, analytical and numerical approaches would be applied to de-risk the underground hydrogen storage.
This project aims to achieve the following three objectives: 
i. Identification of geochemical reaction processes and thermodynamics of the hydrogen-brine-rock system with various minerals at reservoir pressure and temperature to quantify the hydrogen conversion and contamination.
ii. Quantification of the impact of hydrogen-brine-rock interactions on fracture mechanics to de-risk the storage integrity.
iii. Development of a technical screening tool to assist industry to evaluate the potential risks of hydrogen storage integrity due to hydrogen-brine-rock interactions. 
This project if successful, will aim to deliver the following outcomes to benefit the region and the nation as a whole. First, establishing a robust experimental and computational framework and then develop design guidelines that enables large-scale long-term hydrogen storage in a technically feasible and socially acceptable way. Second, this project will position Australia at the forefront of large-scale long-term hydrogen underground storage technology, and make the development of the hydrogen technology supply chain more globally competitive. Third, the identification of the geochemical reaction process of hydrogen-brine-rock system would also reveal the oxidation of ferrous sediments into ferric sediment, which may clarify the role of H2 in undercover iron deposit exploration for iron ore and natural hydrogen reservoirs exploration.  

An Internship opportunity may also be available with this project.
