PhD Position Anodic H2O2 Production in Alkaline Water Electrolysis

Updated: about 2 months ago
Job Type: Temporary
Deadline: 21 Dec 2020

The project will be a mix of literature research, design engineering, experimental work, supported by theoretical analyses and numerical simulations. In collaboration with Nouryon, Hanzehogeschool Groningen (Entrance) and the university of Groningen, a suitable electrolyte, catalyst, and membrane will be selected. In collaboration with TechnipFMC and Hydrogenics, optimized cells will be developed.

Development of a one-dimensional semi-empirical multiphysics model validated by experiments will allow calculation of the polarization curve for different geometrical and operational parameters. The effects of concentration polarization due to hydrogen peroxide, product cross-over through the membrane, and bubble-induced over-potentials are of particular interest.
Finally, the learnings will be used to assess the feasibility of water oxidation to H2O2.

The RELEASE program will work on new technological opportunities in electrochemical energy storage: hydrogen production, hydrocarbon production from CO2 and flow batteries. The consortium includes over 40 researchers from 7 universities and 25 partners. This research complements the work being carried out within the TU Delft e-Refinery research initiative.

Hydrogen will be an indispensable ingredient in the transition towards a sustainable future. It can be used to store large amounts of energy, or used in the production of liquid fuels and chemicals. The cheapest way to produce ‘green’ hydrogen is through alkaline electrolysis, using renewable electricity. In this process, besides hydrogen, also oxygen is produced. Alternatively, using the right catalyst and cell design the much more valuable product hydrogen peroxide can also be produced.

You will be embedded in the Department of Process & Energy, within the section Large-Scale Energy Storage. The ambition of the Department of Process & Energy is to perform world class education and research in the area of process and energy for a sustainable development. We focus our research on the following areas: Energy Technology, Engineering Thermodynamics, Large Scale Energy Storage, Intensified Reaction and Separation Technology, Fluid Mechanics, and Multiphase Flow. We are situated in the Process and Energy lab, a modern and inspriring academic environment with unique experimental facilities. For more information, click here .

The section Large Scale Energy storage focuses its research on storage of electricity, on the scale of solar plants and wind farms and on process integration with thermo-chemical conversion of bio- and waste resources. It aims at bridging the gap between electricity load and demand, especially needed for highly intermittent energy sources like solar and wind. The main theme of the group is the conversion of power to preferably high energy density liquid fuels and chemicals where sustainably produced hydrogen is coupled to a (biobased) carbon source e.g. CO2, CO or C.
