Junior Researcher in Screening Subsurface Hydrogen Storage Sites
Are you interested in developing screening methods to enable subsurface H2 storage? If you enjoy working at the interface between geoscience and engineering then this project may be right for you.
Job description
The geological storage of hydrogen is a promising alternative for large-scale energy
storage in support of expanding renewable energy systems. The North Sea has hundreds
of depleted and abandoned gas fields that are potential storage sites. Robust screening procedures are necessary to select the most suitable reservoirs in terms of geology.
Using advanced geological modelling and numerical simulation techniques, this position will investigate the geological controls on hydrogen storage in depleted natural gas fields of the Bunter sandstone, an important formation in the North Sea. Specifically, the position will investigate how chemical reactions impact the recovery rates of hydrogen during cyclic hydrogen storage, and how engineering designs (e.g., well controls) can be optimised to maximise hydrogen recovery given the different depletion states of the reservoirs.
The ultimate aim is to develop a set of geologically-informed screening techniques and performance criteria that enable us to quickly assess rank and identify the most promising fields for cyclic hydrogen storage such that they can be assessed in more detail using traditional reservoir characterisation, modelling, and simulation techniques.
The specific tasks for this project are:
- Adapt the open-DARTS simulator to account for chemical reactions during subsurface hydrogen storage and calibrate reaction parameters using experimental data.
- Perform numerical simulations of subsurface hydrogen storage including chemical reactions for an ensemble of geological models that were developed in the Rapid Reservoir Modelling software.
- Develop an experimental design to quantify how reservoir properties and engineering parameters impact the recovery rate and overall performance of subsurface hydrogen storage.
- Analyse the simulation results to identify clusters of typical reservoir behaviours and link these clusters back to geological properties to understand (i) how we can engineer the reservoir to maximise the performance of cyclic hydrogen storage and (ii) develop screening paramters that allow us to rank and prioritise the most promising reservoirs.
- Liase with the geoscientists and reservoir engineers from the sponsoring company to present and review the results (through presentations and reports) and regularly meeting with these experts to discuss the next research steps.
- Present the results at conferences and prepare manuscripts for peer-reviewed publication.
Job requirements
- Strong understanding how we can integrate reservoir characterisation and reservoir engineering to improve the management of low-carbon energy sources such as geothermal energy, CO2 storage, or hydrogen storage.
- Demonstrable experience in simulating and analysing coupled multi-physics processes (e.g., heat and fluid flow, chemical reactions and fluid flow) related to low-carbon energy sources in the subsurface.
- Hands-on knowledge in Python programming.
- Experience in working with open-source reservoir simulation software, including adapting the software for specific simulation exercises.
- Experience in developing and applying screening and clustering techniques to group simulation results and identify and quantify representative flow behaviours.
- Excellent communication skills, both in written and oral form.
- An independent and problem-solving approach to research.
- Experience in working in joint-industry projects and working closely with industry partners.
This position is available for candidates who hold at least an MSc degree. Candidates without a PhD degree will be considered if they can demonstrate that they have the relevant experience.
