1. Stand-alone projects with restricted access (like depots for hydrogen-fueled buses)
2. Second generation sites, with public access, but separate from existing gasoline stations (e.g. the facility Shell opened in Iceland in April, 2003 which supplies hydrogen made from water to three city buses)
3. Fully integrated fuel stations (traditional fuels and hydrogen)
4. Within the next five years, mini-network Lighthouse Projects (semi-commercial, public-private partnerships involving multiple energy companies, governments, and fleets of 100 or more vehicles)
5. 2010-2020 connecting the mini-networks with corridors and filling in the white spaces
6. ???
