The Organic Rankine Cycle (ORC) technology is a way to convert heat into electricity. Its main applications are distributed electricity generation from renewable heat sources (geothermal, biomass, solar) and industrial energy efficiency (heat recovery from industrial processes).
The ORC World Map aims to monitor the progress of the Organic Rankine Cycle technology over the world.
The objective is to provide an overview of the ORC market, at the industrial level. This means that small ORC plants at the lab scale or that are not connected to the grid have been ignored. An exception has been made for demo plants that are not connected to the grid but have a significant power output of several hundreds kilowatts / several megawatts.
Some manufacturers do not publish their list of references and declined to take part to that survey. Therefore, this database is not 100% exhaustive. As of September 2017, we can consider that the remaining references do not represent more than 20 MW of installed capacity.
The ORC technology is not very well-known and and the number of power plants that are based on that technology is underestimated. Combining all the known references onto one map can increase public awareness and motivate new motions and incentives favorable to ORC.
Most of the data used is publicly available on manufacturers' websites, through press articles or scientific papers. When possible, multiple sources have been used in order to cross-reference the information. The author thanks all the manufacturers that have taken part to that survey by sending their list of references.
Even if a lot of time and rigour has been spent trying to list all the ORC references, some information may be wrong or missing. Feel free to contact the author (see below) and changes will be made as quick as possible.

Thank you to the ORC manufacturers that have taken part to the survey by sending their list of references :
Special thanks to Tianhang Qi from Enertime for helping to get the data from Chinese manufacturers.
