The California Fuel Cell Partnership has published “A California Roadmap: Bringing Hydrogen Fuel Cell Vehicles to the Golden State,” a report that describes the infrastructure necessary to successfully launch commercial fuel cell electric vehicles (FCEV). The report was put together by stakeholders from industry, academia, non-governmental organisations and government aiming to outline the necessary steps for the vehicle and infrastructure market as it progresses through pre-commercial (2012-2014) and early commercialisation (2015-2017).
The roadmap identifies 68 station locations throughout the state that will serve the first 20,000 FCEV customers with enough hydrogen. Enough stations will give them the confidence that they can choose a FCEV instead of a conventional gasoline vehicle.  The total cost to expand to 68 stations, and provide operations and maintenance support until the stations become profitable is estimated at $65 million.

It also incorporates market-based assessments, models, and tools as well as professional experience with launching advanced vehicles and new infrastructure.
