GM is developing fuel cell-powered vehicles running on hydrogen and emit only water vapor. Fuel cell vehicles are being touted as a way to reduce greenhouse gas emissions and reduce the United States' dependency on pricey crude oil.

General Motors Corp is partnering with Clean Energy Fuels Corp on a new hydrogen refueling station in Los Angeles, which the first station will be near the Los Angeles International Airport and will be the start of hydrogen station network.

The new fueling station will be used by drivers taking part in GM's Los Angeles-area test of its Chevy Equinox fuel-cell-powered car and aims to have 1,000 hydrogen fuel cell vehicles in California between 2012 and 2014 to comply with the state's goal to put thousands of cleaner cars on its roads.

A problem with fuel cells is the lack of an infrastructure for refueling. California currently has only a handful of refueling stations.
