Research and development on cogeneration
Cogeneration has been applied for more than a century and, consequently, it can be considered a mature technology. However, new challenges, such as increased awareness of the depletion of fuels and other natural resources, the pollution of the environment beyond acceptable limits and the scarcity of water in many areas on earth, give the impetus for a continuous research and development (R&D) on cogeneration systems. Samples of this activity are given in this chapter, arranged by the focus subjects of R&D. The reference list cannot be exhaustive; it is indicative only.
