Cargo Ship at Sea


The project focuses on the development and optimal design of a heat-to-power system based on the organic Rankine cycle (ORC) technology, for recovering the waste heat from the cooling circuit of ships’ engines and converting it into electricity.

The benefit of the shipping companies that will adopt this technology is to reduce the fuel consumption of their fleet by 3-4%. At the same time, this new solution contributes to the enhancement of the ship's energy efficiency and to the reduction of pollutant emissions, which are subjected to strict regulations by the IMO.

  • 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 hydrofluoroolefin (HFO), with a very low GlobalWarming Potential (GWP  ̴4).

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