Maritime fuel cell applications: A tool for conceptual decision making

Abstract

The environmental impact of ships needs to be reduced by using more sustainable and cleaner solutions for power generation on board to meet the increasing amount of regulations. Fuel cells are seen as one of the most promising solutions to address this challenge. There are various fuel cell technologies which can be combined with different fuel types, resulting in a large number of options. In order to find the best prospect, a review of the fuel and fuel cell technologies is performed to get an understanding of the possibilities and applicability of fuel cells on superyachts. Various systems were compared on the following characteristics: density, storage type, maturity, safety, and emissions. Based on these characteristics a decision-making tool was developed to assist in the decision-making process considering of many variables. Using this tool, it has become clear that a fuel cell solution should be specifically selected for any different type of application. The required applications or required usage of a fuel cell could lead to the selection of a completely different type of technology.
