Postdoctoral Position in Hydrogen Production by Plasma Electrolysis

The Department of Biological and Chemical Engineering, Aarhus University, invites applications for a Postdoctoral position on Hydrogen Production by Advanced Plasma Electrolysis, and join an international consortium to help Denmark achieve its national and European Climate Goals.

The position is based at AU Viborg and are expected to begin on 1 July 2026, or as soon as possible thereafter.

The Postdoctoral Researcher will play a central role in establishing Denmark’s first demonstration of an advanced plasma-assisted electrolyser for producing hydrogen from biofuels at Aarhus University’s Viborg campus. Working at the intersection of plasma engineering, catalysis, and renewable energy systems, the postdoc will lead experimental design, reactor operation, and data analysis for the integrated plasma–membrane system. The position offers a unique opportunity to collaborate closely with leading industrial and academic partners to deliver groundbreaking results in sustainable hydrogen and carbon production.
 

Expected start date and duration of employment

The position is full-time and expected to begin on 1 July 2026, or as soon as possible.
The expected duration is up to 2.5 years.
 

Job description

The Postdoctoral Researcher will lead the scientific research activities related to the testing, operation, and optimization of the Advanced Plasma Reactor installed at the Aarhus University biogas plant and a smaller lab-based experimental system. The position acts as the central technical and experimental link between the project partners —plasma system provider, membrane purification systems, energy analysis, output users — to deliver validated data on hydrogen production efficiency, process stability, and carbon valorisation.
 

Tasks

• Plan, execute, and document experimental campaigns for biofuels reforming in the plasma reactor under various operating pressures and feed compositions.
• Develop and implement operating protocols for safe, stable, and efficient operation of the integrated plasma–membrane system at the AU Biogas facility.
• Conduct in-depth performance mapping including gas analysis, hydrogen yield, energy consumption, and carbon black morphology.
• Conduct process and plasma simulations as required.
• Collaborate with plasma system engineers to refine reactor configuration and torch parameters; and with H membrane separation scientists to optimize hydrogen separation efficiency and purity.
• Interface with energy systems modelers to supply validated process data for system-level energy and carbon footprint modeling.
• Supervise and mentor MSc and PhD students contributing to process analysis, instrumentation, and data interpretation.
• Lead the preparation of experimental reports, peer-reviewed publications, and contributions to project deliverables and milestones.
• Participate in consortium meetings, conferences, technical reviews, and dissemination events representing the Aarhus experimental platform.

The successful candidates will become part of a collaborative and international environment within the Department of Biological and Chemical Engineering (BCE) at Aarhus University. The positions are mainly based at AU Viborg, home to BCE’s mid-TRL experimental facilities, which support the development and testing of sustainable technologies on pilot scale. Depending on the position, the work will involve a combination of experimental research, process simulation, reactor operation, and system-level optimization.
 

Your profile

We are looking for candidates with strong academic backgrounds and a passion for sustainable, green energy processes and plasma process development. The positions require the ability to work both independently and collaboratively in multidisciplinary teams. Candidates are expected to demonstrate strong problem-solving skills, scientific integrity, and a proactive attitude toward research, engineering, and knowledge sharing.
Please indicate clearly in your application which position(s) you are applying for.

• A PhD in chemical engineering, plasma physics, process systems engineering, electrical engineering, energy engineering, reactor/plasma engineering, or a related field.
• Strong knowledge of plasma physics/thermodynamics, plasma and process modeling, reactor engineering and process integration principles, including mass and energy balances.
• Proficiency in Aspen Plus, COMSOL, PLASIMO, OpenFOAM or similar process and plasma simulation tools.
• Experience with techno-economic assessments (TEA) of complex chemical processes
• Familiarity with CO₂ capture and utilization technologies, Power-to-X systems or plasma processing and reactors.
• Experience in steady-state or dynamic simulation under varying operational scenarios; programming skills are considered a plus.
   

Who we are

The Department of Biological and Chemical Engineering was established on January 1, 2021, in connection with Aarhus University’s reorganization of the engineering area. The department employs around 175 people and is responsible for research and education within the department’s scientific areas. We educate both Bachelors and Master of Science in Engineering and around 825 students are enrolled in our study programs. Furthermore, we also offer an ambitious PhD program. Our PhD students have high academic ambitions and deliver high-quality results for both the private and the public sectors.

At the Department of Biological and Chemical Engineering, focus is on living systems, the biology of organisms, efficient production, and transformation of chemicals, materials and energy. We translate knowledge within biotechnology, food technology, environmental technology, chemical engineering, industrial biotechnology, medical biotechnology and electrochemical engineering, and more into new technologies and value-creating solutions that can also be used in the business community.

Many of our research and development activities are based on companies' specific innovation needs or specialist application areas. Close collaboration with the public sector and private businesses ensures that the knowledge and technology generated in the department's research environments has a clear anchoring in reality and benefits the surrounding society. We also provide research-based public sector consultancy and advice on technology in agriculture and food.
