In Northern California, VTA in San Jose carries hundreds of daily riders on its three hydrogen fuel cell buses. In Oakland and Berkeley, AC Transit carries over 1,000 riders daily on its three hydrogen buses that are plug-in hydrogen hybrids with an added 90kW of batteries per bus. AC Transit supervisors’ fleet of Kia and Hyundai vehicles is growing to ten vehicles. More buses are on order. Other hydrogen stations are coming online in San Carlos, SF Airport, San Francisco and Emeryville.

Next stop is West Sacramento, home of the California Fuel Cell Partnership where the latest exciting vehicles are constantly being driven. The State of California often fuels its fleet of hydrogen vehicles at this station, or at nearby U.C. Davis.

From here we can head north into magnificent mountains, redwood forests, and then dramatic cliffs over the ocean as we head towards Oregon. Before reaching the next state, we arrive at California’s northern most hydrogen station at the Schatz Research Center at Humboldt State University. Station funding was the result of an student team’s national award-winning proposal for of an energy park. Longer term, nearby Diversified Energy and Evergreen Pulp are seeking funding for biomass energy with hydrogen byproduct.

In Canada, Vancouver continues to expand its own hydrogen highway in anticipation of the 2010 Winter Olympics. We will see if Portland and Seattle develop hydrogen stations that would extend a West Coast hydrogen highway over 2,000 miles in length to Whistler, Canada.

Hydrogen transportation continues to grow in California for several reasons including falling vehicle costs, falling fuel price costs, state law to reduce greenhouse gas emissions, and state law to reduce petroleum dependence. California leads the nation in use of solar power, wind power and hydrogen transportation.

Skeptics have valid reasons to doubt hydrogen’s long-term success. The idea of a hydrogen highway was over hyped. A number of stations have hydrogen brought in on diesel trucks from remote reformation of natural gas to hydrogen. This approach offers no source-to-wheels greenhouse gas advantages over gasoline.

Many of the leading hydrogen stations are achieving major source-to-wheels advantages with renewable electrolysis, onsite reformation of natural gas, and use of byproduct and waste hydrogen. Hydrogen fuel cells also extend the range and “recharging speed” of electric vehicles without adding internal combustion engines and the use of petroleum. Hydrogen may be displacing 100 million gallons of gasoline and reducing 500,000 metric tons of CO2 emissions in California by 2020.
