The National Renewable Energy Labs are researching a new way to store renewable energy: in hydrogen. Wind and solar energy are used to create hydrogen and stored in tanks that can be used to power the grid or your car.
While no single alternative to today’s cars and trucks can meet all our needs, fuel cell electric vehicles (FCEVs) are poised to play an important role in America’s portfolio of sustainable transportation options. FCEVs offer long ranges and fast refueling, and emit only water vapor.
Several studies from the U.S. Department of Energy (DOE) indicate that the cost of producing and distributing hydrogen could fall to a cost roughly equivalent to gasoline on a per-mile basis. These studies also conclude that a hydrogen fueling infrastructure for FCEVs is economically viable, requiring an investment comparable to that of the Alaskan oil pipeline to make hydrogen available to 70% of Americans living in the 100 largest U.S. cities.
