Bio

Mustafa Perdawood is a Doctoral Candidate at the University of Lille within the GENIUS Marie Skłodowska-Curie Actions Doctoral Network. His PhD research focuses on energy recovery from underground quarries using geothermal energy storage, with particular attention to the thermal performance, safety, and design of backfilled underground cavities.

He holds an MSc in Mining and Geology from Wrocław University of Science and Technology in Poland, where he studied under the EIT RawMaterials TIMREX programme and also completed an exchange period at Luleå University of Technology in Sweden. He holds a BSc in Geology from Salahaddin University-Erbil in Iraq, where he ranked second in his department and third across the university.

He also has strong IT and programming skills, with experience in Python development.
His research interests include engineering geology, geotechnical engineering, geothermal energy, underground thermal energy storage, numerical modelling, and the sustainable use of underground space. Through GENIUS, he aims to contribute to the development of safe and efficient underground energy storage systems for future low-carbon cities.

Aim

Numerous underground quarries have exploited the subsoil of Lille metropolitan area, mainly in the Chalk layer, at shallow depths, which threaten the stability of adjacent buildings and infrastructures. These cavities are generally filled by cement grout for stabilization depending on the urban needs. The aim is to study the feasibility of exploiting these cavities for seasonal thermal energy storage.

Specific Objectives
  1. Assess the thermal capacity of a backfilled cavity, using prototyping, physical and numerical modelling.
  2. Perform short- and long-term risk analysis (backfill stability, environmental impact, influence of/on the water table).
  3. Design the energy storage system, in particular the ground heat exchanger.
  4. Instrument and monitor an in-situ installation in a cavity in terms of thermal exchange process.
