About the Project

Annual growth in World’s population results in a higher energy demand and a steady increase in CO2 emissions released into the environment, which are mainly originated from fossil fuel sources. In this context, green hydrogen stands as a clean fuel with a high energy content that provides an attractive option to move towards a low carbon energy supply. Green hydrogen is produced from pure water in an electrolyzer operated with electricity from renewable sources. In the process, water is split into oxygen and hydrogen that can be used as fuel. Green hydrogen presents technology challenges for its sustainable implementation, such as low electrolysis efficiencies, high costs, and high water consumption.

The research will focus in increasing the efficiency of green hydrogen production and to assess the viability of operation with alternative water sources to pure water. An experimental assessment of highly active electrode materials will be performed in a custom-built electrolysis cell. The potential of replacing pure water with pretreated wastewater or seawater will be assessed. The project is in line with the Faculty of Engineering and Informatics research theme on Sustainable Environments and will be supervised by an experienced multidisciplinary group with expertise in experimental work, renewable energy, and design of reaction systems.

The successful applicant will be a self-driven and motivated student with a passion about research in the field of renewable energy. Students with a background in chemical engineering or closely related field are encouraged to apply.
