Discover the 33rd IIR Informatory Note on "Cogeneration/Trigeneration"
Energy is a major challenge for the future.
It is a concern connected to environmental issues: global warming in particular is a key issue that has to be addressed by the cooling sector, whose energy demand increases constantly.
As such, a more reasonable use of energy and the development of new technologies for the production of energy are necessary.
Cogeneration and trigeneration: Alternative technologies for energy production
Offering high efficiency through the recovery of thermal waste, cogeneration and trigeneration are valuable alternative technologies for energy production.
The development of cogeneration, which consists of the production of two energies simultaneously, is a viable option for raising the effectiveness of energy use.
Generally, power and heat are produced, and in this case the cogeneration is called Combined Heat and Power (CHP). Trigeneration, also called Combined Cold Heat and Power (CCHP), adds a third energy: cooling.
These technological solutions offer many environmental and economic benefits.
This Informatory Note discusses the operating principles of cogeneration and trigeneration as well as their advantages and challenges.
It was prepared by Michel Feidt (Secretary of IIR Commission E2), Jean-Luc Dupont (Head of the Scientific and Technical Information Department) and Alexis Oger (Informatory Note writer), and was reviewed by several IIR experts.
