Research Assistant in Cryogenic CO₂ Technologies Part-time NEW

Research Assistant in Cryogenic CO₂ Technologies

The Department of Biological and Chemical Engineering at Aarhus University invites applications for a fixed-term position as Research Assistant in the field of cryogenic CO₂ processing and transport technologies. The position is part of a newly funded research project focusing on solid-phase CO₂ logistics, addressing key scientific and engineering challenges related to CO₂ desublimation, reliquefaction, and quality control in emerging CCUS infrastructure. The work combines thermodynamic modelling, process analysis, and pilot-scale experimentation, and is closely linked to ongoing industrial collaboration.

This is a 2–year position starting April 2026, or as soon as possible.

Job Description

The position focuses on research activities related to:

• Cryogenic phase behavior of CO₂ (gas–solid–liquid transitions)
• Thermodynamic and process modelling of CO₂ desublimation
• Operability and control of the dry ice reliquefaction process
• Assessment of contamination risks (O₂, N₂) and hydrate/ice formation
• Analysis and interpretation of pilot-scale experimental data

Depending on background and seniority, the position will emphasize either modelling/conceptual process design or experimental work at pilot scale, with opportunities to contribute to both.

Your Profile

Applicants are expected to have:

• A MSc (for Research Assistant) in Chemical Engineering, Energy Engineering, Process Engineering, Mechanical Engineering, or a closely related field
• Solid background in thermodynamics, heat and mass transfer, or process engineering
• Experience with process modelling/simulation and/or experimental work
• Strong analytical and scientific writing skills
• Ability to work independently and collaboratively in an interdisciplinary environment
• Ability to design, execute, and analyze experiments, including data interpretation and reporting
• Experience with experimental work on cryogenic or pressurized CO₂ systems, including handling of solid and liquid CO₂, is highly desirable

Proficiency in English, both written and spoken, including preparation of technical documentation, scientific manuscripts, and presentations.
