First reference installation of Opcon Waste Heat Recovery technology for ships; potential for 5–10% fuel savings

Green Car Congress

Opcon, in collaboration with Wallenius Marine, recently completed the first reference installation of its Waste Heat Recovery technology for ocean-going vessels in a project supported by the Swedish Energy Agency. Waste heat is used by a heat exchanger to vaporize a working fluid with a boiling point lower than water. The MV Figaro.
