Airport Vehicles are all fleet vehicles. This would eliminate the Diesel pollution from airports such as Los Angeles' and open the door for fleet use of hydrogen. Indian Reservations are another possible application, as large portions often do not have electric power. The cost of line extensions to serve individual customers or villages is prohibitive. Hydrogen energy systems provide a means of supplying reliable power and bringing an improved quality of life to native peoples in remote locations.
Buses represent a major early market for hydrogen.
Many U.S. urban Diesel buses service communities in non-attainment areas for particulates. Diesel exhaust is a major contributor to small particulate emissions which EPA has identified as the most hazardous to human health. Hydrogen power conversion systems are contributors to a solution. In addition to these applications, there is the need to consider hydrogen vehicles in the context of zero-emission vehicle requirements on the 2003 time frame, and fleet vehicles for major corporations, utilities, and governments at all levels. C orridors develop out of the need to connect clusters either to provide chemical feedstocks or a desire for hydrogen transportation between clusters.
