DIFFER DIFFER is het Nederlands Instituut voor Fundamenteel Energieonderzoek; een van de negen onderzoeksinstituten van de Nederlandse Organisatie voor Wetenschappelijk Onderzoek (NWO). Met multidisciplinair energieonderzoek zetten wij ons in om schone energie voor iedereen beschikbaar te maken in de toekomst. Het onderzoek van DIFFER vindt plaats in twee hoofdthema's: Solar Fuels voor de conversie en opslag van hernieuwbare energie, en Fusion Energy voor een schone en oneindige energiebron.
Modelling non-equilibrium plasmas for CO2 activation is very challenging due to the complex network of chemical reactions and different timescales for the physical and chemical processes involved. An accurate description of electron kinetics is fundamental to calculate chemical rate coefficients and transport parameters that are used to describe the plasma discharge. In the CPPC group, we develop fast and accurate computational approaches for electron kinetics. This MSc project focuses on the application of those approaches to CO2 plasmas investigated experimentally at DIFFER.
The discovery of new energy materials is becoming a large-scale challenge that is far beyond the reach of experimentation but also stretching the limits of conventional computation. At DIFFER; our AMD research group is working on to improve the speed and the prediction capability of computational methods for the discovery of new energy materials. We use machine learning (ML), which is essentially a method to make predictions and to optimize a performance criterion based on the available example data.
The computational MSc thesis project is part of a theory-experiment collaboration effort between DIFFER and our industrial partner. The overall aim is to understand the fundamentals of new Fe-based model catalysts, and to tune them further for the Fischer-Tropsch (FT) synthesis of fuels using renewable energy. The fundamental aim is to know how Fe metal layers grow on different Cu metal substrates and how these newly grown Fe layers behave during the adsorption of atomic and molecular species, such as H, C, O, and CO, which are all needed for the synthesis of commercially valuable fuels.

Our future energy infrastructure will need ways of efficiently converting, transporting and storing electricity from sustainable but fluctuating sources. One approach uses sustainable electricity for the reverse combustion of atmospheric CO2 into so-called solar fuels, thereby converting electricity into the chemical bonds of high-density fuels. DIFFER pursues plasma-assisted conversion of CO2 into CO and O2 as an exciting new approach to recycling carbon dioxide into fuels, thereby closing the carbon cycle and eliminating the need for fossil fuels.
Photo-electrochemical (PEC) solar fuel conversion is one of the most promising techniques to convert solar energy directly into its most versatile form of energy, a fuel. However, the efficiency is still low and degradation too high. We have several open BSc/MSc/internship projects for both experiments and modeling & simulation.
