The department of Earth Sciences is looking for a highly motivated candidate for a PhD position at its Experimental Rock Deformation Group external link and Tectonics Group external link.

Your job

Green hydrogen will play a key role in our future energy supply, necessitating large-scale underground hydrogen storage in porous geological formations. Depleted offshore and neighbouring onshore gas fields are considered promising candidates for hydrogen storage in the Netherlands.

While considerable experience has been gained in geological carbon storage, large-scale hydrogen storage presents unique challenges. Hydrogen’s properties, such as low density, low viscosity, and high diffusion coefficient, make it highly mobile and prone to escaping from geological structures. Additionally, the cyclic nature of hydrogen injection and extraction complicates the flow process, influencing geomechanical behaviour and geochemical reactions. The interaction between these different physical processes impacts the caprock integrity, fault leakage, and fluid-rock interactions. The success of large-scale hydrogen storage in porous geological formations depends on both identifying suitable geological sites and strategically managing hydrogen injection-extraction cycles. This PhD project will focus on identifying optimal hydrogen storage sites in the Netherlands, and developing effective operational strategies for storage in porous geological formations.

Within this PhD project, you will interpret subsurface geological structures, identify potential reservoirs, and assess caprock integrity to determine their suitability for hydrogen storage. You will also develop numerical models to simulate hydrogen flow dynamics within the reservoirs, and examine their impact on hydrogen containment, reactive transport, and geomechanical behaviour. You will contribute to the development of best practices for the exploration and operation of large-scale hydrogen storage in porous geological formations. Throughout the project, you will collaborate with the two vibrant research groups, offering diverse expertise in resource exploration, geological modelling, high pressure and temperature experimentation, and coupled multiphysics modelling.

A personalised training programme will be set up, reflecting your training needs and career objectives. About 20% of your time will be dedicated to this training component, which includes following courses/workshops as well as training on the job in assisting in the Bachelor’s and Master’s programmes of the department at Utrecht University.

Your qualities

You have completed your MSc degree in Geomechanics, Geophysics, Hydrogeology, Geological engineering, Reservoir Engineering, or a related discipline by the time the position starts. Preferably, you also have:

• experience or strong interest in reservoir and/or geomechanical modelling using continuum-based numerical methods (e.g., finite element method, finite difference method);
• experience or strong interest in using reflection seismics for subsurface exploration;
• strong quantitative and programming skills;
• the ability to work independently and as part of a team in a multidisciplinary research environment;
• enthusiasm for geo-energy and applications relevant to the sustainable use of the subsurface;
• excellent communication and interpersonal skills.

Due to the international character of our research, good command of spoken and written English is essential. We highly encourage applicants from all members of our community and of diverse backgrounds to join us.

Our offer

We offer:

• a position for one year, with an extension to a total of four years upon a successful assessment in the first year, and with the specific intent that it results in a doctorate within this period;
• a working week of 38 hours and a gross monthly salary between €2,901 and €3,707 in the case of full-time employment (salary scale P under the Collective Labour Agreement for Dutch Universities (CAO NU)); 
• 8% holiday pay and 8.3% year-end bonus; 
• a pension scheme, partially paid parental leave and flexible terms of employment based on the CAO NU. 

In addition to the terms of employment external link laid down in the CAO NU, Utrecht University has a number of schemes and facilities of its own for employees. This includes schemes facilitating professional development external link, leave schemes and schemes for sports and cultural activities external link, as well as discounts on software and other IT products. We also offer access to additional employee benefits through our Terms of Employment Options Model. In this way, we encourage our employees to continue to invest in their growth.

About us

A better future for everyone. This ambition motivates our scientists in executing their leading research and inspiring teaching. At Utrecht University external link, the various disciplines collaborate intensively towards major strategic themes external link. Our focus is on Dynamics of Youth, Institutions for Open Societies, Life Sciences and Pathways to Sustainability. Sharing science, shaping tomorrow external link.

Utrecht University’s Faculty of Geosciences external link studies the Earth: from the Earth’s core to its surface, including man’s spatial and material utilisation of the Earth – always with a focus on sustainability and innovation. With 3,400 students (BSc and MSc) and 720 staff, the faculty is a strong and challenging organisation. The Faculty of Geosciences is organised in four Departments: Earth Sciences, Human Geography & Spatial Planning, Physical Geography, and Sustainable Development.

The Department of Earth Sciences external link conducts teaching and research across the full range of the solid Earth and environmental Earth sciences, with activities in almost all areas of geology, geochemistry, geophysics, biogeology and hydrogeology. The department hosts a highly international tenured staff of over 50 scientists and more than 110 PhD candidates and postdoctoral researchers. We house or have access to a wide variety of world-class laboratories, among which are the Electron Microscopy Centre external link, the Geolab external link, and the Earth Simulation Lab external link.

The department and its facilities are located at Utrecht Science Park. Utrecht is the fourth largest city in the Netherlands with a population of nearly 360,000 and forms a hub in the middle of the country. Its historical city centre and its modern central station can easily be reached from the Science Park by public transport or by a 15-minute bicycle ride. Utrecht boasts beautiful canals with extraordinary wharf cellars housing cafés and terraces by the water, as well as a broad variety of shops and boutiques.
