Postdoc in Dynamic Modelling, Simulation and Optimization of Power-to-X Processes

At the Faculty of Engineering and Science, AAU Energy, a 24-month postdoctoral position in Dynamic Modelling, Simulation and Optimization of Power-to-X Processes is available from 1 January 2027 or as soon as possible thereafter. The project is primarily rooted in process engineering while also addressing interactions between Power-to-X plants and the electrical grid.

Your work tasks

You will develop and apply dynamic process models based on mass and energy balances, thermodynamics, reaction kinetics, and equipment behaviour to simulate integrated Power-to-X plants under changing operating conditions. The work will address renewable fuel production, particularly green methanol and sustainable aviation fuels through methanol-based and Fischer–Tropsch pathways. The work will focus on electrolysers, fuel-synthesis processes, energy storage, heat integration, and interactions with the electrical grid.

You will combine process simulation with operational optimization, process control, techno-economic assessment, and model validation to investigate flexible operation under varying renewable electricity generation and energy prices.

You will collaborate with academic and industrial partners, publish scientific results, contribute to project meetings and deliverables, and present findings at conferences and workshops. The position may also include limited teaching and supervision of bachelor’s and master’s students.

Your competencies

You hold a PhD in chemical engineering, process engineering, or a closely related field, completed by the application deadline. You have documented research experience in process modelling and simulation, preferably including dynamic modelling of chemical or energy processes.

Hands-on experience with Aspen Plus, Aspen HYSYS, or Aspen Dynamics will be considered a strong advantage. Experience with gPROMS, Modelica, or comparable process-simulation tools is also relevant. Strong skills in MATLAB, Python, or a similar computational environment are expected.

Experience with Power-to-X, renewable fuels, optimization, process control, model validation, techno-economic assessment, or grid-integrated energy systems will strengthen your profile.

You will work closely with industrial and international partners. Therefore, the ability to translate research into practical solutions and communicate effectively across disciplines is essential. We value candidates who are proactive, structured, collaborative, and motivated to publish high-quality research and contribute actively to project activities.

Who we are

You will join the Fluid & Process research group at AAU Energy, Campus Esbjerg, where you will become part of an international and interdisciplinary research environment combining process, chemical, energy and electrical engineering. The group works with modelling, simulation, control, optimization and experimental validation of fluid and energy systems, with applications including Power-to-X, carbon capture and utilization, green fuels and sector coupling.

The working culture is collaborative and informal, with close interaction among academic staff, postdoctoral researchers, PhD fellows and students. We share an ambition to contribute to the green transition through research with practical relevance. We offer laboratory and workshop facilities, and a collaborative environment that supports innovation, knowledge sharing, and professional development.
