As of August 2020[update], there were 42 publicly accessible hydrogen refueling stations in California.
[1] The California Hydrogen Highway Network (CaH2Net) was initiated in April 2004 by Executive Order (EO) S-07-04 under Governor Arnold Schwarzenegger with the purpose of promoting hydrogen refueling stations in California.
[2] In September 2006, California Senate Bill 1505 required 33% of hydrogen to come from renewable energy sources,[3][4] and other initiatives followed.
[6] Some of these hydrogen fueling stations completed the terms of their government-funded research demonstration project and were decommissioned.
[9][10] In 2013 Governor Brown signed AB 8, a bill to fund $20 million a year for up to 100 stations.
