Innovative Energy Systems: Motivations, Challenges and Possible Solutions in the Cruise Ship Arena



Primary authors



The effort on environmental issue in the maritime field has led to more stringent regulations on greenhouse gas emission (GHG). The International Maritime Organization has developed regulations intended to increase the ship’s efficiency and reduce GHG emissions in a design phase. In this perspective, several approaches and technologies adopted in land-based engineering can also be advantageous for marine applications. This is the case of Distributed Energy Resources (DER) solution applied in land electrical solutions, based on microgrids, which increases both the system’s efficiency and reliability. In fact, also shipboard power systems are microgrids with large centralized generation units and distributed loads. This work is primarily focused on methodological aspects of a DER solution on-board cruise ships, with the aim to permit the integration of different energy sources.(e.g. fuel cells, micro-turbines and energy storage systems) pursuing more flexible, reliable and sustainable ships. At the same time, as another land-base engineering best practice further investigated in the paper, the thermal energy recovery issue on board is going to be revisited. This issue can be in fact be better studied and implemented thanks to the DER solution.
