GE is offering hybrid propulsion systems for military and commercial applications based on its LM series gas turbines using electric motors and drives, to reduce noise and emissions through improved fuel economy. GE has a wide experience of hybrid systems, acting as systems integrator, GE is able to team with other industry suppliers to provide all electric propulsion solutions. A particularly successful combination with gas turbines is the CODAG or CODOG arrangement where diesel engines are employed at low output with the gas turbine(s) only used to produce boost power. As the cost of fuel increases, such solutions are not limited to newbuilds, repowering of existing vessels can also provide tangible financial benefits. In the future wider use of fuel cells can replace diesel engines to provide further reductions in exhaust, noise and vibration emissions. [More]
