Energy Efficient Hull Form Design for A Pleasure Boat Powered by A Solar-Hydrogen Energy System

摘要

Throughout the history many energy devices are used for ship propulsion purposes. From the earliest ships with manpower to ships driven by nuclear energy, in the 21st century renewable energy technologies are included to the research of energy efficient and environmental friendly propulsion. Fuel cells and photovoltaic solar energy technologies are the most promising renewable energy sources for land, sea or air vehicles. In this study the design of a convenient hull form for limited power supply and suitable general arrangement is investigated for a pleasure boat powered by a 8.5 kW fuel cell. In addition as an auxiliary energy source solar panels depending on the usable surface area are included. For energy efficient hull form and sufficient space requirements of solar panels, monohull, catamaran and trimaran forms are analyzed in terms of required power. The effect of the side hull positions are investigated and compared in the case of trimaran in longitudinal and transversal directions to optimize the appropriate location of the side hulls for low resistance.
