This chapter is a continuation of ultracapacitor application case studies with focus on heavy transportation. Public transportation systems and vehicles in particular are becoming more of a focus by regulatory agencies as a sector to promote energy efficiency. Energy efficiency now has the connotation of energy security, offsetting of imported oil, and moderation of climate change through reduced emissions. All of these reasons mesh well with the trend to hybridize heavy transportation. Consider for the moment transit buses, the type we are most familiar with as a city bus, and one that is typically powered by a large CIDI engine burning diesel fuel.
