The project uses the hybrid cooling, heating and power (HCHP) concept developed for military expeditionary applications to recover engine exhaust heat of every sizable diesel generator for microgrid applications. The recovered waste energy is converted to cooling, heating and/or power through a combined power and cooling cycle. This can reduce diesel fuel consumption by 30% for the targeted military application. The same technology can also be useful for industrial waste heat recovery to convert the vast amount low-grade waste heat to usable energy. When integrating concentrated solar thermal energy during daytime operation, significantly more fossil fuel can be saved leading to greater greenhouse gas emission reduction.
