PhD studentship in Green hydrogen from electrolysis of biowaste at University of Strathclyde

Biomass electrolysis is a novel process that can cost-effectively turn untreated biowaste into green hydrogen through two steps: (i) Thermal Digestion to abstract protons from biomass using a redox active catalyst at mild temperatures; (ii) Electrolysis of the reduced catalyst solution using a proton exchange membrane (PEM) flow cell to produce H2. This process has the potential to produce hydrogen of equivalent purity and pressure to state-of-the-art water electrolysis technology, with less than half the electrical energy input required. We have previously trialled the utilisation of biowaste from the Whisky distillery industry for this process [1] and aim to build a modular biomass electrolyser at the capacity of up to 1kW for processing liquid and/or solid biowaste.

The PhD project will design, build and test a modular biomass electrolyser that integrates the separation and recirculation of acid catalysts for continuous operations, to be instrumented for measurements of the temporal evolution of the relevant quantities (i.e. hydrogen yield, cell voltages, temperature, pressure, catalyst usage/recycling, etc, plus uniquely, catalyst/redox mediator state of charge). Support from NMIS will contribute to design and prototyping of the electrolysis flow cell stack. The PhD project will also conduct process modelling to help optimise a scalable integrated design for continuous redox cycling of the catalyst with biomass input and output of products. 

In addition to undertaking cutting edge research, students are also registered for the Postgraduate Certificate in Researcher Development (PGCert), which is a supplementary qualification that develops a student’s skills, networks and career prospects.

Funding Notes

Studentship funding covers UK Fees and Stipend. To be eligible for this funding, applicants must be classified as a home student. We require that applicants are under no restrictions regarding how long they can stay in the UK. Eligible candidates will be selected on the basis of an interview.  Students applying should have (or expect to achieve) a minimum 2.1 undergraduate degree in a relevant engineering/science discipline, and be highly motivated to undertake multidisciplinary research.
