California's Hydrogen Transportation Initiatives

This page last reviewed December 7, 2015


As zero emission vehicles (ZEVs), hydrogen fuel cells play a significant role in reducing California's greenhouse gas and smog emissions. The California Air Resources Board's most recent Advanced Clean Cars Program builds upon the ZEV Regulation in place since 1990, and rapidly increases numbers of ZEV technologies, such as hydrogen fuel cell and battery electric vehicles. By mid-century, 87% of cars on the road will need to be full ZEVs. This will place California on a path to reducing greenhouse gas emissions by 80% by 2050, a goal adopted by many nations and believed necessary to stabilize climate temperature.

Hydrogen Stations


Hydrogen Cars & Buses







California has 13 research hydrogen fueling stations, 9 public stations and an additional 18 that have been funded and are expected to be operational in the next few years. Some of these stations have been co-funded by the State of California.

The California Fuel Cell Partnership's (CaFCP) hydrogen fueling station map provides details and status of all hydrogen fueling stations in the State.

Their California Road Map describes the infrastructure that will be needed to successfully launch the commercial fuel cell electric vehicle (FCEV) market.

Under AB 8, ARB annually reports on an evaluation of the deployment of Fuel Cell EVs and hydrogen fueling stations in CA. In order to identify areas of greatest need for fueling infrastructure, ARB has developed the CA Hydrogen Infrastructure Tool (CHIT).

Policy & Funding


Other Hydrogen Resources & Programs




The State's actions to fund hydrogen stations, cars, shuttle buses and transit buses include: Initial Hydrogen Vehicle Infrastructure funding provided over $25 million for hydrogen transit buses, light duty passenger vehicles, and hydrogen stations. The State has provided co-funding for 9 stations. Assembly Bill 118 (Nuñez Statutes of 2007) directs the California Energy Commission (CEC) to prepare periodic Investment Plans for the Alternative and Renewable Fuel and Vehicle Technology Program. The program currently makes available approximately $100 million to co-fund alternative fuels projects, a portion of which has been set aside for hydrogen infrastructure.

The California Hydrogen Highway Network (CaH2Net) was initiated in April of 2004 by Executive Order S-07-04. The mission was to support and catalyze a rapid transition to a clean, hydrogen transportation economy in California.

The CaH2Net was a public-private partnership directed by the California Air Resources Board (ARB), using the California Hydrogen Highway Blueprint Plan (May 2005) as its guiding document. Learn more about the CaH2Net.
