This paper evaluates the lifecycle costs and carbon dioxide emissions of different types of city buses. The simulation models of the different powertrains were developed in the Autonomie vehicle simulation software. The carbon dioxide emissions were calculated both for the bus operation and for the fuel and energy pathways from well to tank. Two different operating environment case scenarios were used for the primary energy sources, which were Finland and California (USA). The fuel and energy pathways were selected appropriately in relation to the operating environment. The lifecycle costs...

Partly in response to ongoing environmental and energy security concerns, and with supportive government policies, the total number of electric vehicles (EVs) has been rapidly increasing in the last years worldwide. The growing EV penetration into the electric power system changes the electricity consumption profiles and leads to challenges for different stakeholders such as transmission system operators and electric utilities. Electric utilities benefit from having information of EV charging to forecast any additional load and peaks, to understand temporal and spatial aspects, and to...

Over the last several decades, hydrogen fuel cell vehicles (FCVs) have emerged as a zero tailpipe-emission alternative to the battery electric vehicle (EV). To address questions about consumer reaction to FCVs, this report presents the results of a “ride-and-drive” clinic series (N=182) held in 2007 with a Mercedes-Benz A-Class “F-Cell” hydrogen FCV. The clinic evaluated participant reactions to driving and riding in an FCV, as well as vehicle refueling. Pre-and post-clinic surveys assessed consumer response. More than 80% left with a positive overall impression of hydrogen. The majority...

The "hydrogen energy station" is one method of hydrogen production at small and medium scales. Unlike more conventional hydrogen station designs where hydrogen is simply delivered or produced on-site with a fuel "reformer" or water electrolyzer and then compressed and dispensed, energy stations would provide multiple functions in the same facility. They would integrate systems for production of electricity for 1) local uses and/or the utility grid, 2) re-use of thermal energy "waste heat" for building heating/cooling needs, and 3) purified hydrogen for refueling vehicles.Hydrogen energy...
