California's Hydrogen Transportation Initiatives

This page last reviewed December 12, 2018


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


AB 8 Annual Evaluations







Through its AB 8 program, the State of California has co-funded 62 hydrogen fueling station projects. Many of these stations are currently open. ARB's latest analysis projects that all funded station projects will be open for retail hydrogen sale to the public by 2020.

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).

Staff from the Air Resources Board (ARB), California Energy Commission (Energy Commission), and Governor’s Office of Business and Economic Development (GO-Biz), along with other state agencies, closely coordinate and work with other government and industry stakeholders to implement actions that support the development of a robust hydrogen and FCEV market.

Assembly Bill 8 (AB 8; Perea, Chapter 401, Statutes of 2013) remains a crucial driver to ensure California is prepared for commercial launch of FCEVs by providing a specific focus on development of the state’s hydrogen fueling station network. AB 8 dedicates up to $20 million per year to support continued construction of at least 100 hydrogen fuel stations. This focus will enable hydrogen FCEVs, along with other zero emission vehicle (ZEV) technologies, to play a significant role in meeting multiple policy objectives established by Governor Brown and the Legislature.

In addition to AB 8 and ARB’s Scoping Plan, Governor Brown’s Executive Order B-16-201211 provides another strong policy driver for accelerating commercialization of FCEVs and their associated hydrogen fuel station network. These policy drivers give clear direction for the ARB and CEC to plan and fund the state’s hydrogen fuel station network for its growing FCEV market.

The State of California is co-funding the initial network of hydrogen fueling stations, in advance of vehicle launches, through the Energy Commission’s Alternative and Renewable Fuel and Vehicle Technology Program (ARFVTP).

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.
