The Western Australian State Government conducted a trial of three hydrogen fuel cell buses between 2004 and 2007. The trial was run in conjuction with similar trials in Europe under the banner of the Clean Urban Transport for Europe (CUTE) project. The aim of these trials was to develop and demonstrate an emission free and low noise transport system that would contribute to cleaner environmental conditions, increase public knowledge and acceptance of hydrogen and fuel cell technology and to build a strong foundation for regulation and certification of fuel cell technology.

The Western Australian trial, undertaken in the capital city of Perth, successfully demonstrated the technical feasibility and public acceptance of the operation of hydrogen fuel cell buses in Western Australia. Considerable hurdles remain, however, in achieving commerical viability and in developing low greenhouse emissions sources of hydrogen supply.

The Western Australian government is currently exploring opportunites for further trials of hydrogen vehicles and associated refuelling infrastructure
