Dr Julien Mouli-Castillo

  • Lecturer in Geo-Energy Systems (Systems Power & Energy)

Biography

I am driven by my contributions to making the world we live in a cleaner, safer and pleasant place to live. I strive to do so by researching how to achieve a rapid and fair energy transition to help us mitigate the worst impacts of climate change.

I have a BSc in Environmental Geosciences from UCL, an MSc in Carbon Capture and Storage from the University of Edinburgh and PhD in Geology and Geophysics also from the University of Edinburgh. 

Research interests

  • Geo-Energy: My work in geological energy explores the potential of geological formations, such as saline aquifers and hydrocarbon fields, for energy and carbon storage. I assess their capacity and suitability for these purposes, contributing to the development of geologically-based energy solutions.
  • Energy Storage: My work in energy storage includes conducting scoping studies on inter-seasonal compressed-air energy storage systems and underground hydrogen. I also have an interest in other energy storage technologies, such as using disused mines as thermal storage solutions.
  • CCUS (Carbon Capture, Utilisation, and Storage): My research involves investigating safe and useful uses for long-term carbon storage in geological formations. These efforts are crucial for mitigating greenhouse gas emissions and combating climate change.
  • Hydrogen: Regarding hydrogen, I have been actively involved in projects related to assessing hydrogen storage capacities in various geological formations, and evaluating the feasibility of hydrogen as a clean and versatile energy carrier for various applications, including transportation and industry.
  • Renewable Energy: My research in renewable energy integration focuses on innovative approaches to integrating offshore wind energy with underground hydrogen storage systems. This synergy aims to provide reliable and sustainable energy solutions while addressing intermittency challenges associated with renewable sources.
  • Energy Policy and Infrastructure: I have an interest in examining energy policy and infrastructure to identify regulatory and commercial barriers to the adoption of geo-energy systems.
  • Geothermal Energy: In the field of geothermal energy, I explore the extraction of heat from abandoned mines, a sustainable approach to utilising low-enthalpy geothermal resources for heating and other applications, contributing to the decarbonization of heating systems using secure local resources.

In summary, my research spans a wide spectrum of technologies, each with a specific focus on advancing their efficiency, safety, and sustainability. These efforts collectively contribute to the broader goal of transitioning to a more environmentally friendly and sustainable energy landscape.
