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.

This paper shows the results of an in-depth techno-economic analysis of the public transport sector in a small to midsize city and its surrounding area. Public battery-electric and hydrogen fuel cell buses are comparatively evaluated by means of a total cost of ownership (TCO) model building on historical data and a projection of market prices. Additionally, a structural analysis of the public transport system of a specific city is performed, assessing best fitting bus lines for the use of electric or hydrogen busses, which is supported by a brief acceptance evaluation of the local citizens. The TCO results for electric buses show a strong cost decrease until the year 2030, reaching 23.5% lower TCOs compared to the conventional diesel bus. The optimal electric bus charging system will be the opportunity (pantograph) charging infrastructure. However, the opportunity charging method is applicable under the assumption that several buses share the same station and there is a “hotspot” where as many as possible bus lines converge. In the case of electric buses for the year 2020, the parameter which influenced the most on the TCO was the battery cost, opposite to the year 2030 in where the bus body cost and fuel cost parameters are the ones that dominate the TCO, due to the learning rate of the batteries. For H2 buses, finding a hotspot is not crucial because they have a similar range to the diesel ones as well as a similar refueling time. H2 buses until 2030 still have 15.4% higher TCO than the diesel bus system. Considering the benefits of a hypothetical scaling-up effect of hydrogen infrastructures in the region, the hydrogen cost could drop to 5 €/kg. In this case, the overall TCO of the hydrogen solution would drop to a slightly lower TCO than the diesel solution in 2030. Therefore, hydrogen buses can be competitive in small to midsize cities, even with limited routes. For hydrogen buses, the bus body and fuel cost make up a large part of the TCO. Reducing the fuel cost will be an important aspect to reduce the total TCO of the hydrogen bus.
