Internship | Electrocatalytic CO₂ Reduction for Next‑Generation E‑Fuels

Are you motivated to tackle climate change through science and engineering? Curious about how we can transform CO₂ into sustainable aviation fuels and high value chemicals? Join our team and contribute to cutting edge research on electrocatalytic CO₂ conversion, with a strong focus on materials development and scaling technologies for real world impact in aviation and beyond.

You will take an active role in both research and development, combining experimental work with scientific analysis.

Your activities will include:
Getting started and building knowledge

• Explore the latest literature on CO₂ electroreduction and synthetic fuel pathways
• Understand catalyst materials, especially copper based systems for ethylene production
• Learn about electrochemical reactor and cell design

Materials and device development

• Design and fabricate novel electrodes
• Investigate materials that improve conductivity, selectivity, and durability

Experimental research

• Perform electrochemical CO₂ reduction experiments
• Optimise operating conditions such as electrolyte composition, humidity, and current density
• Analyse performance in terms of efficiency, selectivity, and stability

Collaboration and communication

• Discuss results with a multidisciplinary team
• Contribute ideas and improvements to the project
• Present your findings in reports and presentations

What will be your role?
In this internship CO2 reduction will be studied to produce ethylene on copper catalyst due to its preferable selectivity. The electrodes will be manufactured using various techniques and then used to prepare a membrane electrode assembly stack. Composition of the electrodes and assembly procedure of this stack and the cell operating conditions will be varied to find the most optimal configuration.
An approximate description of the activities to be encountered during this project are:
Performing literature review and gain acquainted with:

• Materials to produce ethylene via electrocatalysis.
• Electrode design strategies.
• Electrochemical cell design.

CO2 reduction via electrocatalysis

• Investigation of strategies to manufacture gas and liquid diffusion electrodes with different catalysts.
• Manufacturing custom MEAs.
• Electrochemical experiments with full data analysis.
• Participating in active discussion with colleagues about your results.
• Reporting and presenting your findings.

What you will gain
This internship offers a hands on experience at the forefront of CO₂ conversion and sustainable fuel technologies.
You will work on a real world challenge, contributing to the development of technologies that aim to decarbonise aviation and enable scalable electrofuel production.

During your internship, you will gain:

• Practical experience in electrochemistry, catalysis, and energy materials
• Insight into scaling up technologies from lab to industrial relevance
• Experience working on CO₂ to fuel pathways, including synthetic aviation fuels
• Close mentorship and guidance throughout your project
• The opportunity to take ownership of your work and explore your ideas
• A collaborative environment with experts from different disciplines

• You are available for an internship of at least 6 months, ideally during your MSc phase. Please include your availability and preferred start date in your application.
• You have a strong interest in the energy transition and sustainable technologies.
• You are curious, proactive, and enjoy tackling complex challenges.
• You are comfortable working independently as well as collaborating within a team.
• You communicate clearly in English.

Students from disciplines such as chemical engineering, materials science, chemistry, or related fields are encouraged to apply. If your background is different but you are excited about the topic, we would still love to hear from you.

After the first CV selection, the application process will be conducted by the concerning department. TNO will provide a suitable internship agreement. If you have any questions about this vacancy, you can contact the contact person mentioned below.

Important to be aware of before applying:

• Before the start of the internship, the internship agreement from TNO needs to be signed. For students at a college or university based in the Netherlands, TNO uses the UNL-template (supplemented with a number of specific agreements from TNO). For students of foreign and MBO educational institutions, the TNO internship agreement applies. TNO does not sign any other internship agreements.
• Before the start of the internship, the educational institution will need to confirm in writing that:
  • 1) You are enrolled at the educational institution during the internship, and;
  • 2) The internship takes place as part of the programme of the study.

• The confirmation of educational institution takes place by signing the UNL template or forms prepared by TNO.
• Interns at TNO must be in possession of a Dutch residential address at the start of the internship. Performance of internship activities from abroad is not possible.
