What will you be doing?

Our near future will rely on sustainable electricity production technologies, such as wind and solar energy. These sources are by nature unpredictable and intermittent - furthermore, the existing grid infrastructure is not yet ready to support the upcoming and fast-growing capacity on green electricity. Stationary electrical energy storage, in particular redox flow batteries, will become key players in this energy transition movement, allowing to fill the gap between the pace, timing and amount of renewable electricity supplied and demanded by the society.

At TNO, the research on redox flow batteries is successfully on-going - this year, the Energy Conversion and Storage group (Sustainable Process and Energy Systems department) will design a dedicated set-up to our battery to be able to study and optimize the performance of our affordable and environmentally benign system. A redox flow battery is a complex multi-component system that can be more simply broke down to a power supply, a cell stack with membrane, electrodes and current collectors, and electrolyte reservoirs. All aspects of its design need to consider its final purpose: create a high capacity battery which can provide highly efficient charging/discharging cycles during a long life cycle.

The group is looking for an enthusiastic BSc./MSc. student for a graduation project under the tittle "Set-up up design and performance optimization of an affordable and environmentally benign redox flow battery", for a period of time of 6 to 9 months. The following research questions should be covered:
  • What are the fundamental parameters to be considered into the design of a redox flow battery system?
  • How to re-design a standard redox flow battery configuration to our specific redox pair and electrolyte of choice?
  • What are the strategies to maximize the energy output out of a redox flow battery?
  • How could such a system be connected to an external realistic energy supply?

What do we require of you?

We are looking for a motivated student in the final stages either a bachelor or a master studies in Chemical Engineering, Process Technology, Mechanical Engineering or Chemistry, but with a preferred interest in Electrochemistry Processes. You want to develop technology that will shape the energy transition and help building a more sustainable society. You are comfortable with literature review and eager to understand the fundamentals of the technology through carrying experiments in the lab. You are safety-oriented and responsible.

What can you expect of your work situation?

TNO is an independent research organisation whose expertise and research make an important contribution to the competitiveness of companies and organisations, to the economy and to the quality of society as a whole. Innovation with purpose is what TNO stands for. With 3000 people we develop knowledge not for its own sake but for practical application. To create new products that make life more pleasant and valuable and help companies innovate. To find creative answers to the questions posed by society. We work for a variety of customers: governments, companies, service providers and non-governmental organisations. Working together on new knowledge, better products and clear recommendations for policy and processes. In everything we do, impact is the key. Our product and process innovations and recommendations are only worth something if our customers can use them to boost their competitiveness. 

You will be a team member of the enthusiastic Energy Conversion and Storage group, working side by side with experienced and creative engineers and scientists. You will be located in Delft, in the middle of the bustling TU campus, in a department which focuses in many topics around energy transition. You will be able to make important connections for your professional network, with people developing technology not only for electricity storage, but also heat storage, CO2 capture, storage and utilization, electrochemistry and circularity.

What can TNO offer you?

You want to work on the precursor of your career; a work placement gives you an opportunity to take a good look at your prospective future employer. TNO goes a step further. It’s not just looking that interests us; you and your knowledge are essential to our innovation. That’s why we attach a great deal of value to your personal and professional development. You will, of course, be properly supervised during your work placement and be given the scope for you to get the best out of yourself. Naturally, we provide suitable work placement compensation.
