California already boasts 23 hydrogen fueling stations (14 more are slated to be built this year) and has put 137 hydrogen-powered passenger cars and 9 buses on the road, more than any region in the world, according to Chris White of the California Fuel Cell Partnership. Although the partnership is still operating in a “demonstration phase,” notes White, several of its members (many of which are automotive companies) expect to make hydrogen-powered commercial vehicles as early as 2010, and to have showroom cars by 2015. According to White, this is the same way hybrid-electric cars were introduced to the market in the 1990s. Hydrogen is coming!
