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.

New composite reduces rare earth element usage in three-way catalytic converters

Green Car Congress

The TWC reduces NO x to nitrogen and oxygen; oxidizes CO to CO 2 , and oxidizes unburnt hydrocarbons to carbon CO 2 and water. This function is crucial in current TWC, in which the oxygen partial pressure in the exhaust must be regulated to be near the ideal air-to-fule ration (A/F = 14.6). —Machida et al. Click to enlarge.
