Postdoctoral Researcher in Process Modelling, Integration and Techno-Economic Analysis of Reversible Solid Oxide Electrolysis and biomethanation systems

Postdoctoral Researcher in Process Modelling, Integration and Techno-Economic Analysis of Reversible Solid Oxide Electrolysis and Biomethanation Systems

Applications are invited for a two-year postdoctoral position in process systems engineering at the Department of Biological and Chemical Engineering, Aarhus University, Denmark.

The successful applicant will contribute to a collaborative research and demonstration project focused on integrating reversible solid oxide electrolysis and fuel-cell operation with biogas production, biological methanation, and heat recovery. The research will combine process simulation, system integration, optimisation, and techno-economic analysis to evaluate flexible operation and support the scale-up of the technology.

This is a two year position from 1st of February 2027 or as soon possible.

The successful applicant will contribute to a collaborative research and demonstration project focused on integrating reversible solid oxide electrolysis and fuel-cell operation with biogas production, biological methanation, and heat recovery. The advertised position has become available through an Energy Technology Development and Demonstration Programme (EUDP) Project from the Danish Energy Agency, called DyneMe. The project aims to demonstrate how a 300 kW second-generation Dynelectro electrolyser unit can boost biogas methane production from existing feedstock, maximise energy efficiency and provide grid-balancing capabilities through dynamic electrolyser load and when relevant fuel cell operation. The research will combine process simulation, system integration, optimisation, and techno-economic analysis to evaluate flexible operation.

The main tasks include:

• Developing process models, for all core unit operations, in Aspen Plus or comparable process-simulation software.
• Establishing mass and energy balances for electrolysis, fuel-cell operation, anaerobic digestion, biochemical methanation, biogas processing, steam production, and heat recovery.
• Evaluating the interaction between variable hydrogen production and biological hydrogen uptake.
• Identifying and evaluating heat-integration opportunities between the solid oxide system and the biogas facility.
• Simulating representative operating conditions, including part-load operation, hot standby, and SOEC and SOFC operating modes.
• Combining process-model results with time-series or dispatch models to assess operation under variable electricity prices, renewable-electricity availability, biogas production, and heat demand.
• Conducting techno-economic, sensitivity, and uncertainty analyses.
• Participating in regular project meetings and present the modeling activities.

Applicants should hold a PhD in chemical engineering, process engineering, energy engineering, biochemical engineering or similar.

The successful candidate is expected to have:

• A strong background in process modelling, thermodynamics, mass and energy balances, and chemical or energy-process design.
• Extensive experience with Aspen Plus, Aspen HYSYS, or comparable process-simulation software.
• Experience in developing, analysing and validating models of chemical, biochemical, electrochemical, or energy-conversion processes.
• Experience with process integration, including pinch analysis and heat exchanger network design.
• Documented experience with techno-economic analysis, including sensitivity and uncertainty analysis.
• Experience with quantitative data analysis and a relevant programming or numerical-computing environment, such as Python or MATLAB.
• The ability to work independently, structure a complex modelling problem, document assumptions, and deliver results according to project deadlines.
• Documented ability to have scientific results of high quality published in peer-reviewed journals
• Excellent written and spoken English.
• Good communication and collaboration skills and an interest in working in an interdisciplinary project involving both academic and industrial partners.

Experience in one or more of the following areas will be considered an advantage:

• Dynamic process simulations
• Mathematical optimisation
• Development of surrogate models
• Electrolysis, fuel cells, hydrogen production or other electrochemical processes
• Biogas production, anaerobic digestion, biological methanation

The place of work is Gustav Wieds Vej DK-8000, and the area of employment is Aarhus University with related departments.

Applications must be received no later than 27th of November.

Shortlisting is used. This means that after the deadline for applications – and with the assistance from the assessment committee chairman, and the appointment committee if necessary, – the head of department selects the candidates to be evaluated. All applicants will be notified whether or not their applications have been sent to an expert assessment committee for evaluation. The selected applicants will be informed about the composition of the committee, and each applicant is given the opportunity to comment on the part of the assessment that concerns him/her self.
