Energy, Storage, Conversion

Lecturer(s): Jean-Pierre CLOAREC
Course ⋅ 16 hStudy ⋅ 12 h


This course is a synthesis of all the physical phenomena used for energy storage and conversion. For every 2 hours lecture, a specialist from ECL presents the fundamental phenomena of a field: batteries, thermal solar, solar photovoltaic, electromechanical conversion, energy and radiation, combustion, bioenergy. Matter stores energy in various forms. Energy density, capacity to store and dispense energy depends on the nature of the energy conversion implemented: weak, nuclear, electromagnetic, gravitation... The cycles and transformation processes allowing the conversions and exchanges of energy will be studied emphasizing the engineering linked to the particularly renewable energies (solar, wind, biomass). This course provides a better vision of the scientific challenges about energy storage and conversion. Students work on mini-projects of their choice, to practice technico-economic dimensionning of energy systems dedicated to concrete cases with final users.

Learning Outcomes

  • Systemic approach: model an energy system based on several disciplines, identifying the couplings between disciplines.
  • Systemic approach: argue and discuss the choices made to design a complete energy system. Question the relevance of the validation criteria.
  • Implement positive interactions within the mini-project team
  • Carry out a state-of-the-art study on an open problem on technical-scientific-economic issues related to an energy need. Formalize the outcome. Demonstrate a broad vision taking into account technological, economic, human and environmental issues.
