An Undergraduate Research Project: The Design and Development of an Environment Friendly Hybrid BoatAs the concern for environmental protection of the Earth rises, the renewable energy resources asa clean energy sources attracts more attention. The technical developments of renewable energysuch as solar energy, wind energy, wave energy, kinetic energy (human power) are beingpursued on a ever growing basis.One example of a renewable energy source used for everyday living is to examine the possibilityof a propulsion system that combines renewable energy sources (wind, solar, and human power)with the hydrogen fuel cell system for a kind-to-the-environment hybrid boat. Boats which runon battery power have existed for some time. However, the low energy-density in batteries, aswell as the unreliability due to the evaluation of the residual battery energy, has made it difficultfor application to a larger ship. Accordingly, a system which can be applied to battery-poweredsailing has been developed and the system was named a Hybrid Electric Boat (HEB). It is hopedthat development of the HEB will contribute to the knowledge concerning environmental issuesand will reduce the use of oil. An 18 ft-length boat was converted to be completely batterypowered with the batteries are charged by renewable energy systems such as solar, wind, humanpower, and hydrogen fuel cell system. Hydrogen fuel cells might be the next revolution intransportation, because it is a low cost, zero emissions solution to our dependency on oil.Essentially, hydrogen fuel cells work by converting compressed hydrogen gas into electricityusing a polymer electrolyte membrane, with only byproducts of heat and water. Hydrogen is alsothe most abundant chemical element in the universe, occupying 75% of all the universe’selemental mass. A new energy storage and conversion system for boat hybrid propulsion hasbeen developed. Some simulation models have been built for initial sizing of the storage systemand testing all of the propulsion system. A reduced scale prototype of the whole HEB system hasbeen developed to verify the results obtained through simulation in number of operatingconditions. Experimental results confirm the validity of the proposed approach. The results of thetests will be provided in the paper.The research is primarily focused on fuel, cost and performance efficiencies. The research beingdone here is truly groundbreaking; there are only a handful of companies worldwide creatingmainly hydrogen powered boats. The project team has confidence that theoretical studies whichdovetail with the project would be beneficial for the students’ scientific knowledge.Experimental studies completed as part of the project would provide contributions to our nationalHEB design.The use of 3D parametric modeling and one-dimensional simulation and analysissoftware tools are applied to create the design and analysis of the HEB. Students are exposed toHEB concepts while participating in this project by using one-dimensional analysis andsimulation, modeling software tools, and hands-on techniques.
