The project:MotivationThe development of hydrogen energy technologies is central to the UK government's ten-point plan for a green industrial revolution, targeting a 40% reduction in gas consumption by 2030 and carbon-zero emissions by 2050. Ensuring the safe, sustainable operation of hydrogen storage and delivery systems, including the integrity of storage containers and pipelines, is essential to achieving these goals. However, as this transition is still in its early stages, there is a shortage of technologies specifically designed to detect and monitor hydrogen-induced defects. These defects, which can initiate at the microstructural level, pose significant risks, as they can lead to catastrophic failures in critical components, compromising safety and performance across hydrogen-related industries and impacting the aerospace, energy, and automotive sectors. Advanced detection and characterization of these early-stage defects are therefore crucial to supporting both industrial safety and the broader green energy transition.AimThe project aims to develop an ultrasonic array technique to detect issues in high-value hydrogen storage containers and pipelines, and, based on these results and structural integrity assessments, potentially monitor their health in situ if needed. The focus will be on detecting, characterising, and monitoring hydrogen-induced defects, such as blistering, embrittlement, and cracks. This will be achieved by integrating ultrasonic arrays with inverse modelling methods to interpret historical data. Additionally, the project will explore the failure mechanisms of these defects to better understand their development and impact on structural integrity.As a PhD student, you will collaborate with academics from the UNDT group at the University of Bristol and have the opportunity to work with engineering teams at the Manufacturing Technology Centre (MTC). This will provide you with valuable real-world experience within an industrial setting, allowing you to engage directly with workplace practices and culture.How to apply:Prior to submitting an online application, you will need to contact the project supervisor to discuss.Online applications are made at . Please select Mechanical Engineering (PhD) on the Programme Choice page. You will be prompted to enter details of the studentship in the Funding and Research Details sections of the form.Candidate requirements:Applicants must hold/achieve a minimum of a merit at master's degree level (or international equivalent) in a science, mathematics or engineering discipline.
