Green hydrogen from water electrolysis is becoming an important ingredient in realizing the energy transition, by storing large amounts of intermittent electricity and as a base chemical. However, hydrogen from water electrolysis is still too expensive to compete against the hydrogen from fossil based sources, which is slowing down the energy transition. The cost of green hydrogen production has to be reduced strongly in the coming years, to enable an economically sustainable energy transition. Therefore, your help is needed in developing the required innovations to improve the efficiency of electrolysis and to reduce the capital costs of electrolyzer systems.
Energy losses associated with reaction kinetics and gas-bubble evolution are some of the most important losses in an electrolyzer and directly impact the cost of green hydrogen. Suppressing these losses are of significant research interest and recent efforts have shown some innovative ways to do so. It was shown that the electrical resistances due to gas bubbles and those associated with reaction kinetics, are sensitive to the application of magnetic fields and to the use of time-varying voltages. Very high frequency voltage oscillations have shown to improve the reaction rates multi-fold, while low frequency spatially varying patterns can promote the release of bubbles. In addition, magnetic fields have also been proven to aid bubble removal as well as improve reaction rates.
However, further understanding of these concepts are required to harvest their full potential and to successfully scale them up. Through this project, you will develop an in-depth understanding of these two concepts from a system perspective and evaluate their potential for scale-up. You will work closely with HyET E-Trol B.V. on this project. HyET E-Trol is the industrial partner sponsoring this project.
