Rigid Wing

When a sailing ship which has large rigid wing sails such as the Wind Challenger Sail runs in a sufficiently windy sea, the thrust by sails is utilized to not only drive the ship at the proper speed but also to rotate an underwater turbine at significant speed and torque. The turbine generates electricity which is used for the electrolysis of water to generate hydrogen. The hydrogen is stored using toluene in the form of methylcyclohexane (MCH), which is in liquid form under normal temperature and pressure. MCH is stored in the ship's tank as hydrogen fuel. In the case of weak winds when the sails cannot generate sufficient thrust, using the hydrogen generated by the dehydrogenation device, the fuel cell works and supplies electricity to the electric motor propeller for the ship's propulsion. Thus, the ship can run at a constant speed regardless of wind speed and direction.

This article focuses on production of a hydrogen fuel system for a DaimlerChrysler fuel cell minivan by Millennium Cell Inc., a developmental-stage company based in Eatontown. Millennium Cell’s hydrogen-on-demand system stores hydrogen in the form of sodium borohydride, a chemical whose chief use today is for bleaching paper. Mixed with water, the chemical makes a fuel that can be stored as a liquid in plastic vessels under ambient temperature and pressure. The mixture is neither flammable nor explosive. Millennium Cell continues its research. It is attempting to drive down catalyst costs. Improving catalyst durability is another constant challenge. The company continues making key changes in the packaging of its hydrogen-on-demand technology to reduce the space it occupies. As for Millennium Cell’s researchers, their desks filled with abundant technical challenges, they undoubtedly have plenty to do besides worrying about the future.

Design And Manufacture

The paper presents the current development of the AOS-H2 electric motor-glider project. The project encompasses the design and manufacture of an electric propulsion system (EPS) and a CF/epoxy airframe to be used as a flying test platform for the designed EPS. A 40-kW electric motor is supplied by a 10-kW PEM fuel cell stack and a Li-ion battery during run-up and ascent and by the fuel cell stack alone during steady flight. The airframe and the EPS have been completed; the results of bench tests of the EPS have proved that it meets the established requirements..

Carbon Based

With an increasing emphasis on emission restrictions and environmental impact of carbon-based energies, transportation industries are rapidly focusing on research, development, and implementation of zero-emission fuels and technologies. In the United States, the maritime industry provides key transportation services for people and goods. Immediate and future legislation at the state and federal levels are beginning to push passenger vessel operators to seek more carbon-neutral propulsion methods and begin the necessary transition towards a zero-emission future. Small high-speed, zero-emission vessel concepts are being introduced in the United States, most notably the SWITCH project of San Francisco. The SWITCH project aims to put the first hydrogen fuel cell e-ferry into service in 2021. To date, the zero-emission fast ferry efforts have focused on smaller passenger vessels. This paper examines the potential design elements and operating conditions required for a large (450 passengers) high-speed vessel to meet zero-emission standards. Key ferry metrics of speed and passenger capacity are studied with this concept hull to compare a zero-emission propulsion system against a more traditional carbon-based system. To account for major project decision factors, the economics/cost and regulatory restrictions of a hydrogen fuel cell system are considered for a high-speed passenger vessel of this scope. A sensitivity analysis is performed to determine the technological and performance gains necessary for fuel cell power to match the current capabilities of carbon-based powers. Future development of zero-emission technologies is discussed to evaluate the continually improving opportunities for such a large high-speed vessel.
