The newly developed waste heat recovery system "HydrocurrentTM Organic Rankine Cycle (ORC) Module 125EJW (Hydrocurrent is a trademark of Calnetix Technologies) by Mitsubishi Heavy Industries Marine Machinery & Engine Co., Ltd. (MHI-MME) has begun operation on the vessel named Arnold Maersk belonging to Maersk Line, MHI-MME said in its press release.

The ORC system enables the utilization of extremely low temperature heat sources to generate electrical power at low-cost and high-efficiency in marine applications. In concrete terms, the system generates electricity using the waste heat of the main engine jacket cooling water (approx. 85°C), and by reducing the load on the vessel's main generator, cuts CO2 emissions and improves the efficiency of the vessel's plant.
The ORC has an output of 125 kW and is fitted to the Arnold Maersk. Prior to this, a pilot ORC machine completed performance testing at the factory of Calnetix Technologies who is a partner of MHI-MME, gaining the approval of ClassNK and Lloyd's Register of Shipping in 2015.
