Sub-surface storage
Master Sciences de la Terre et des planètes, environnementParcours Geosciences for the energy system transition


This course is focused on underground storage concerning CO2, methan and heat. Key elements would be given to students to consider geologic storage as a viable technology for reducing atmospheric emissions. An overview of storage capacity in Europe would be addressed. In this framework, it would be necessary to address concerns related to leakage from the primary storage reservoir and demonstrate that gas can be injected and stored safely in the geological formations. Risks and hazards associated with geological storage would also be addressed. Finally, active and passive monitoring methods will also be discussed through applied cases, in addition to the seismic methods already covered in the Monitoring teaching unit.

Compétences visées

At the end of this unit, the student will be able to:

  • Describe the main types of storage and associated issues (geological nature, petrophysical characteristics, ...)
  • Identify suitable storage sites using geological prospecting tools and data
  • Describe the qualification process of a storage site and its life cycle
  • Define modelling tools to optimise site management (injected volumes, recovered volumes, transfer time, etc.)
