[School of Engineering PhD Scholarships] Investigating heat transfer in advanced geothermal systems; integration to different sources of demand

About the project

About the Project The transition to a low-carbon energy system requires new solutions that can simultaneously address climate change and energy security. Geothermal energy offers a significant opportunity as a reliable, low-carbon source of heat that can complement intermittent renewable energy technologies. However, conventional open-loop geothermal systems can involve significant geological uncertainty and risks associated with fluid circulation, including induced seismicity, fluid losses and uncertainty in reservoir performance. Advanced Geothermal Systems (AGS), which circulate fluid through closed-loop systems deep within the subsurface, offer a promising approach to mitigating these risks. However, AGS remain relatively untested at real-world scale, and significant questions remain regarding their heat-transfer performance, optimal design and integration with energy demand. This project will investigate heat transfer in AGS and their integration into wider energy systems. The research will develop numerical models to simulate subsurface heat transfer across low- to high-temperature geothermal settings, incorporating geological characterisation and operational conditions. The project will explore new AGS configurations that can be optimised for different geological environments and investigate how these systems can be operated flexibly to match variable heating and cooling demand. University campuses, with their significant and diverse thermal demands, will provide real-world case studies through which the potential of AGS to provide reliable and flexible low-carbon energy can be assessed. The project will deliver new understanding of heat transfer in closed-loop geothermal systems and establish how AGS design and operation can be optimised according to geological conditions and energy demand. The research will contribute new numerical modelling approaches and potentially novel AGS configurations, while providing practical evidence for their deployment in real-world settings. Ultimately, the project aims to help establish whether AGS can provide a scalable, low-risk and flexible source of low-carbon heat, supporting both decarbonisation and energy security. The student will receive training in state-of-the-art numerical modelling and simulation software, alongside developing their own mathematical and computational models to address research questions that cannot be captured by existing tools. The project will involve close collaboration with researchers and colleagues at the University of Manchester and Keele University, providing access to expertise across geothermal engineering, geology, geophysics, numerical modelling and energy systems. The student will benefit from working within a multidisciplinary research environment and will develop transferable skills in computational modelling, geological characterisation, model development and energy-system integration.
