The Net Zero Industry Act (NZIA), presented for the first time by the European Commission in March 2023, considers the production of green hydrogen to be a strategic industry. Hydrogen could account for 20% of the EU’s energy mix by 2050, including 20-50% of energy demand in transport and 5-20% in the industry. Water electrolysis is a promising technology to decrease the worldwide strong reliance on fossil fuels and support the development of a climate-neutral economy. Green hydrogen electrochemically generated with renewable power sources (e.g. solar, wind energy, etc.) is a clean and carbon-neutral energy carrier that can be stored, transported and re-transformed using a fuel cell to electricity with water as only by-product.

A large-scale (GWs) deployment of electrolysers is necessary to fulfil the ambitions of the European Green Deal in the context of the Hydrogen strategy for a climate-neutral Europe. Europe’s current target is to reach a maximum annual production capacity of 25 GW for electrolysers by 2025. The European Commission suggests that the EU should deploy a cumulative capacity of 100 GW of electrolysers by 2030 (with a target of 40% of total electrolyser deployment being made in Europe). The current European objective is to produce 10 million tonnes of green hydrogen by 2030.

There are various electrolysis technologies. The three most prominent of which are: alkaline water electrolysis (AEL), proton exchange membrane electrolysis (PEMEL), and solid oxide electrolysis (SOEL). Each selected technology has its unique characteristics and applications, yet the general chemical reaction is the same for all three.

To allow large-scale deployment, several common challenges remain to be tackled:

i) the limited stack durability and lifetime,

ii) the absence of detection and monitoring tools to predict an optimal, easily adjustable operational parameter space to decrease degradation phenomena driven by the operating conditions,

iii) ensuring reliable operation under fluctuating energy input,

iv) requirements to decrease system costs (in particular the total cost of ownership).

In the “DELYCIOUS” project funded by Horizon Europe and the EU Clean H2 Partnership, Air Liquide, Fraunhofer IWES, Horiba France, Dumarey Softronix, ETA Florence, Stargate Hydrogen, Sivonic, and University of Twente will combine forces to meet these challenges by developing Diagnostic tools for ELectrolYsers that are Cost-efficient, Innovative, Open, Universal and Safe. These diagnostic tools will first be validated at the lab-scale for all three technologies, AEL, PEMEL and SOEL followed by a TRL 6 demonstration of the developed electrolyser management system (EMS) with a 460 kW AEL stack.

Your principal task in the project will be the development of integrated multiscale multiphysics models of AEL and PEMEL cells and stacks. For this, you may leverage a hierarchical modelling methodology developed previously for SOEL. The models should couple mass, charge and energy transport phenomena across the cell and stack to relevant heterogeneous electrochemical reactions at the electrode-electrolyte interfaces. After model validation, you will use the AEL and PEMEL cell and stack models to create multidimensional datasets consisting of time-resolved solutions of the models. The datasets will then be used by project partners to develop the condition monitoring scheme at the heart of the EMS. A model reduction step may also be necessary here. Finally, you will compare the cell and stack models to long-term AEL and PEMEL cell and stack measurements conducted by project partners to identify and capture dominant degradation modes and parameters.

• You have a PhD in chemical engineering, chemistry, applied physics or a related field.
• You have a strong track-record and experience in physics-based modelling of AEL and PEMEL cells and stacks.
• You have experience coding in C++/Python/Julia.
• You are an excellent team player in an enthusiastic group of scientists and engineers working on a common theme.
• You are creative, like to push boundaries, and are highly motivated to address a major challenge for the low carbon energy and materials transition.
• You are fluent in English and able to collaborate intensively with external parties from academia and industry in regular meetings and work visits.

• A full-time position for 36 months;
• Your salary and associated conditions are in accordance with the collective labour agreement for Dutch universities (CAO-NU);
• You will receive a gross monthly salary ranging from € 4.020,- to € 5.278,- (salary scale 10) based on education and work experience;
• There are excellent benefits including a holiday allowance of 8% of the gross annual salary, an end-of-year bonus of 8.3%, and a solid pension scheme;
• A minimum of 232 leave hours in case of full-time employment based on a formal workweek of 38 hours. A full-time employment in practice means 40 hours a week, therefore resulting in 96 extra leave hours on an annual basis;
• Free access to sports facilities on campus;
• A family-friendly institution that offers parental leave (both paid and unpaid).

You will be a part of the Sustainable Electrochemical Engineering and Digitalisation (SEED) lab (https://www.utwente.nl/en/tnw/seed/). SEED is co-hosted by the groups Catalytic Processes and Materials and Inorganic Membranes in the Faculty of Science and Technology at the University of Twente. At SEED, you will join a team of 7 highly motivated PhD and postdoctoral researchers all working to accelerate electrochemical technology development for the low carbon energy and materials transition by bridging nano-scale physics to industrial-scale systems.

Your application should include

• a 1 A4 page cover letter, emphasizing why you would be a good fit for the position,
• a detailed CV including the name and e-mail address for at least two references, and
• a half A4 page summary of your PhD research.

An interview (or two) comprising of a scientific presentation followed by discussion will be part of the selection procedure. Following a pre-selection, short-listed candidates will be invited for interviews 1-2 weeks after the application deadline.
