The large-scale carbon neutral production of ‘solar’ fuels and base chemicals like hydrogen and syngas, ammonia, and methanol using only renewable electricity, water, and air will play a pivotal role in the transition towards a sustainable energy system. This can be done efficiently in electrochemical reactors, similar to electrolysers, fuel cells, and redox flow batteries.
The aim of these PhD projects is to make a step in our quantitative understanding of the evolution of gasses inside porous electrodes, including the effect of liquid flows. These gases may be the desired products, but their presence can also adversely impact the performance.
The PhD positions focus on, respectively:
1) The pore level: using advanced 3D multiphysics simulations in COMSOL and in-house code. Based on the continuum Poisson-Nernst-Planck equations, often overlooked electrokinetic effects as well as bubble nucleation and evolution will be included. By contributing to ongoing and future PhD projects there will be ample opportunity to be involved in various applications.
2) The electrode level: using a powerful combination of multiscale simulations, experiments, and imaging for optimal understanding. The important effect of gas bubbles on the energy losses is the primary concern in this project, which focuses on hydrogen production through alkaline electrolysis. There are already various experimental efforts ongoing in this direction that can be benefited from.
3) The cell level: the electrochemical conversion of CO2 is a promising avenue for sustainable production of liquid hydrocarbons. The efficiency of this process can be strongly improved using properly applied liquid flows. Using hydrodynamic understanding, prototyping, and physical and possibly microkinetic modeling, an optimized state-of-the art overall design is the goal of this PhD research.
Common to all projects are (multiphase) fluid dynamics, physical transport phenomena, and some electrochemistry. Depending on the project and the background of the candidate, part of these topics may be learnt or refined during the course of the PhD. Given the multi-disciplinary nature and societal relevance, these projects are expected to provide a challenging but stimulating and rewarding learning experience.
We are looking for highly motivated and assertive candidates with a sharp mind for critical and creative thinking and good communication skills in English.
An MSc in an applied science or an engineering discipline like applied physics or mathematics, mechanical-, aerospace-, or chemical engineering or equivalent is required as well as a proven affinity with and skill for mathematical and computational modelling or experimental skills respectively, depending on the position applied for.
