Two world-leading European marine engine manufacturers, MAN Diesel & Turbo and Wärtsilä Corporation, have agreed to pursue a large joint research project, the HERCULES-C project, as a continuation of the very successful HERCULES programs for the research and development of marine engine technology. The overall vision of the HERCULES research program is for sustainable and safe energy production from marine power plants. The technological themes of the HERCULES initiative have, since its inception in 2002, been higher efficiency, reduced emissions, and increased reliability for marine engines. However, for taking marine engine technology a step further towards improved sustainability in energy production and total energy economy…
