The chemical industry is among the largest sectors in the UK, contributing nearly £25 billion to the economy. However, it is also a major source of industrial greenhouse gas emissions, releasing 8.8 million tonnes of CO2 equivalent annually. This accounts for 19% of the UK's industrial emissions and 2% of the country's total emissions. In the transition towards NetZero, there is significant interest in phasing out fossil fuels as both the energy source and precursors in the chemical sector. With a circular economy mindset, one attractive solution is acquiring the fossil fuel alternatives from the accumulated waste stream. Therefore, in this project, we aim to develop an alternative electrolysis process, that utilises ethylene glycol derived from waste polyethylene terephthalate (PET) to produce hydrogen and value-added chemicals towards decarbonisation of the chemical sector. Au-based catalyst has previously been demonstrated to show good reactivity, high chemical stability and poison tolerance towards ethylene glycol electrooxidation (EGOR). Herein, we will develop a high-performance Au-alloyed thin film electrode using a magnetron sputtering technique that can produce nanoscale thin film catalysts with precise structure control. Furthermore, the economic and environmental sustainability of this novel electrolysis process will be evaluated at larger scale through a comprehensive techno-economic and life-cycle assessment and benchmarked against state-of-the-art water electrolysis, to guide further technology development. The innovation lies in the >50% reduced energy input required for hydrogen production in this process compared to standard water electrolysis, along with the high-value product stream generated on the anode, which directly contributes to decreasing the cost of green hydrogen, strongly aligning with the £2.8/kgH2 UK government's target for 2050. By utilising green hydrogen as an energy carrier in chemical production and replacing fossil fuels with plastic waste for producing high-value chemicals, our novel solution can improve waste management and help reduce the 8.8 million tonnes of CO2 emitted annually by the UK chemical industry. Our project aligns with UKRI's vision for a greener future, and the UK's net-zero research framework. The project's interdisciplinary approach spans from material science, electrochemistry, operando spectroscopy and chemical engineering. The implementation of this ambitious research project is strengthened by a broad collaborative network, including the UK chemical industry (Johnson Matthey), national institute (National Physical Laboratory), and cross disciplinary academics from the University of Surrey, Manchester Metropolitan University, and the University of Nottingham. This network will foster future collaboration and expand the project's scope beyond the initial proof-of-concept.
