Welcome to the website of the Knowledge Center on Organic Rankine Cycle technology! 



Organic Rankine Cycle (ORC) power systems are an efficient and reliable option for the generation of electricity in the small to medium power range (from few kWe up to tens of MWe). They are especially suitable for waste-heat to power and renewable energy sources like solar radiation, biomass thermal conversion, geothermal heat exploitation. A very promising application is waste heat recovery from mobile engines (internal combustion engines, gas turbines, etc) on board of trucks, ships, trains, and aircraft.



We have released a position paper on the proposal to ban the use and production of PFAS (Per- and polyfluoroalkyl subtances) in the EU, which was recently submitted by five European authorities to the European Chemical Agency. You can read our position paper by clicking here.







ORC 2023: 4-6th September 2023






Registration is currently open for the 7th international Seminar on ORC power systems (ORC2023) will take place in Seville from 4 to 6 September 2023.

The is the leading conference relating to ORC power cycles and is supported by the KCORC. The seminar provides an exciting opportunity for scientists from industry and academia to discuss the latest advances in research & development, applications and demonstration projects related to ORC power cycles, and related technologies.

It will be a real pleasure to meet again in person to discover the latest advances of the ORC community in the beautiful city of Seville!

You can find more information about the event on the conference website.

The Thermal Energy Harvesting Advocacy Group (TEHAG) is extremely pleased to announce the release of the white paper titled "Thermal Energy Harvesting - the Path to Tapping into a Large CO2-free European Power Source".

This report aims to help foster general public knowledge / awareness and policy and regulation regarding the enormous potential of waste-heat-to-power technologies, and therefore the use of ORC power plants and systems for both stationary and mobile applications.
