Prospects and Challenges for the Future of Marine Power Systems

抄録

Marine power systems are facing the need for bringing an innovation to the recent regulatory requirements for greener transportation. The reduction of greenhouse gas emission is the most crucial challenge. Improvement in thermal efficiency of engine systems, without an increase in NO_X emission rate, is strongly encouraged for lowering the CO₂ emission. The use of low carbon fuels such as natural gas would be of great interest to reduce CO₂ and NO_X/SO_X emissions. In the near future, a variety of alternative fuels would be within the scope of the marine transportation sector including hydrogen and ammonia, both with zero carbon content. Another important technical trend is information technology. Autonomous ships are now in focus as a future marine transportation to ensure a safer and more economical voyage, where power systems are required more controllable and with less maintenance. The presentation provides an overview of the urgent challenges to respond the requirements of the environmental regulations and to introduce advanced technologies.
