Internship | Electrofuels

Rising CO2 levels and its negative impact on the global climate is a major problem facing humanity today. Apart from the large-scale efforts taken to curb the CO2 emissions, another alternative is to sequester them at large industrial emitters and further electrochemically convert the CO2 to organic feedstocks/valuable compounds like, methanol, ethylene, formic acid, etc. A key technological challenge to enable such a process is the design the materials that effectively reduce the CO2 at low over-potentials and generate the desired products at high current densities and do so without forming unwanted by-products. Due to the poor solubility of CO2 in aqueous electrolytes. For this reason, it is preferred to work with gaseous electrolyte in one of the electrochemical half-cells. The other half utilizes liquid electrolyte that provides necessary humidity to the membrane separating the half cells and the electrolyte’s conductivity is e enhanced with additional ions stemming from for example KOH. Membrane conductivity and selectivity plays a key role in the overall cell performance and lifetime, making it prime contender for further development.

In this internship CO2 reduction will be studied to produce ethylene on copper catalyst due to its preferable selectivity. The copper-based nanostructures will be synthesized using various techniques and then used to prepare an ink to coat the electrode. This electrode will then be combined with membrane and counter electrode to form the membrane-electrode assembly (MEA) stack. Composition and assembly procedure of this stack will be varied to find the most optimal configuration.

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.
