EPSRC DTP Studentship - Hydrogen Production through Wastewater Reuse and Integration

This project seeks to develop a process model for the reuse of wastewater streams for hydrogen production and direct integration into industrial feedstocks, and to use techno-economic analysis to evaluate the feasibility of doing so, using real facility data as case studies. 

Currently, nearly all hydrogen is produced from fossil fuels. Industries which use hydrogen as a feedstock could reduce their carbon footprint by using renewable energy to electrolyse water. 

This work will identify where this would be feasible, considering cost, hydrogen need, and wastewater makeup. It will identify industries which might benefit from this type of process intensification, and then will extend to gather specific data about the wastewater constituency from various industries. It will develop case studies identifying the specific makeup of the wastewater, the current disposal method, the current source of hydrogen, specific constituents of concern for electrolyzers, and specific constituents which are of environmental concern. 

This project will then develop an appropriate process train using unit operations and process modelling for the purification and electrolysis for hydrogen production of wastewater for specific industries. This will be supported by a techno-economic analysis to understand the economic implications of implementing such a system. This will be extended by optimizing the process train and operating point to maximize financial viability or minimize the environmental load. 

Outcomes from this work include a set of case studies of industries which benefit most from reusing wastewater to produce hydrogen; a set of process models to describe the energy, additive, material and equipment needs of the process; and a techno-economic analysis model to optimize process designs for financial cost or environmental burden. 

This project encourages the circular resource economy and identifies strategies for decarbonizing feedstocks from critical industries through process integration of wastes and feedstocks. It will provide specific recommendations and pathways to reduce carbon dioxide emissions, and the environmental load from wastewater releases. 

EPSRC DTP studentships are fully-funded (fees and maintenance) for eligible UK students. Full eligibility criteria can be found via the following link; https://www.postgraduate.study.cam.ac.uk/finance/fees/what-my-fee-status 

Applicants should have (or expect to obtain by the start date) at least a good 2.1 degree in engineering, or similar. Background knowledge of electrochemistry, water chemistry, or computational methods is beneficial. 

Applications should be submitted via the University of Cambridge Applicant Portal https://www.postgraduate.study.cam.ac.uk/courses/directory/egegpdpeg/finance, with Dr. Nathanial Cooper identified as the potential supervisor by 9 April. Applications may close early if the position is filled before the advertised date. 

The University actively supports equality, diversity and inclusion and encourages applications from all sections of society.
