Cement factories, electric thermal power plants, steel factories etc where an exhaust energy is lost. In the field of renewables can be also cited: Geothermal power plant: ORC can be applied to the exhaust of Geothermal plants with output temperatures from 100ºC to 400º C.

The fuel cell produces a power output of 1198 W at a current of 24A. It has 50% efficiency and hence produces an equal amount of waste heat. That waste heat is used to drive an organic Rankine cycle (ORC), which in turn produces an additional 428 W of power at 35% efficiency.

Organic Rankine Cycles (ORC) are systems that can effectively recover low-grade heat for electric power generation. For ORC to be a viable technology, it should operate safely and efficiently under variable operating conditions due to exogenous and operating specifications changes.

ORC's can recover heat from waste streams at lower temperatures than is possible with conventional steam Rankine systems, and because ORCs operate at relatively low pressure, they can operate unattended and fully automated in most locations.
