Study 29: Cogeneration / trigeneration: opportunities to improve the performance of waste heat recovery systems

The rational use of energy, a key concern in the context of the energy transition and the fight against climate change, has also become a major geopolitical issue in recent years.

Among the solutions for reducing energy consumption, the recovery of waste heat from industrial processes (which would otherwise be lost) is a key factor. To maximise this recovery, multi-energy-vector utilisation via cogeneration and trigeneration (the simultaneous production of electricity, heat, cooling or mechanical energy) may be of particular interest.

The aim of this ALLICE study is to explore opportunities for improving the performance of waste heat recovery systems, with a focus on technologies (ORC, thermal compression cooling and heating), and to investigate the associated financing solutions.
