Echogen Efficient Exhaust System

GE to be exclusive provider of marine exhaust system, enhancing its own propulsion systems

Posted on February 8, 2013

GE Marine has signed an agreement with Echogen Power Systems, Akron, Ohio, U.S.A., to be the exclusive provider of Echogen’s heat-to-power system for use on commercial and military marine vessels worldwide. Echogen’s product enhances GE Marine’s mechanical, hybrid and all-electric propulsion system solutions.

Echogen’s system, operating across a broad range of exhaust temperatures, captures the exhaust heat energy that typically vents to atmosphere from gas turbines and/or diesel engines and converts it to useful power. While this concept is not new, Echogen said its technology uses supercritical CO2 (sCO2) as its working fluid, which allows for a more compact, lighter and economical configuration than traditional steam systems.

In the first quarter of 2013, Echogen said it will be testing a 7 MW sCO2 engine system.
