The research project has as main objective the development and the optimum design of an Organic Rankine Cycle (ORC), for the waste heat recovery of the marine engines’ cooling system and its conversion in electricity in order to cover the ship’s needs. Main objective of the project is to focus on shipping, while the main benefit of the proposed technology is the reduction of the ship’s fuel consumption up to 3-4%, but also the reduction of the CO2 and other harmful emissions (NOx, SOx, etc).

   The project goals to be achieved are:

•      The system development covering the spatial, operating and connection limitations.

•      Optimum control and full incorporation of the innovative technology in the ship’s energy management system.

•      Construction of the prototype ORC of power 15kWe.

•      Pilot operation onboard for six months.

•      Business plan development and wide dissemination of the project’s results.


   The project’s innovations are:


•      ORC design for shipping.

•      Conservation of the system’s high efficiency for full and part load, depending on the gases’ thermal load.

•      Use of 4th generation organic fluid for the ORC, of type hydrofluoroether (HFE), with a very low Global Warming Potential (GWP  ̴4).

•      Plug in-plug out design for easy, fast and low-cost establishment.
