ORC stands for Organic Rankine Cycle.

The Rankine Cycle, firstly described by William John Macquorn Rankine in 1859 and more commonly known as the steam cycle, is a thermodynamic cycle used to convert heat into work.

The ‘old-fashioned’ Rankine cycle is used in most steam power plants and uses water that is evaporated into steam to power a turbine, which is connected to a generator. The same principle is held for ORC, but organic fluids or refrigerants are used instead of water.

In spite of highly efficient processes, there is still a vast amount of energy lost as waste heat.

By using an organic fluid with a molecular mass higher than and a boiling point lower than that of water, an ORC machine can convert this low temperature waste heat into work. This mechanical energy is then transformed into green electricity using a generator.

Limited resources and volatile prices for fossil fuel, combined with the effects of global warming, have urged engineers to speed up the further development of this clean energy technology.
