Hydrogen & Fuel Cells

Watch this video to find out how fuel cell technology generates clean electricity from hydrogen to power our buildings and transportation—while emitting nothing but water. Learn more about hydrogen and fuel cell technology basics.

Fuel cells produce electricity from a number of domestic fuels, including hydrogen and renewables, and can provide power for virtually any application -- from cars and buses to commercial buildings. This technology, which is similar to a battery, has the potential to revolutionize the way we power the nation while reducing carbon pollution and oil consumption.

The Energy Department is working to increase fuel cell deployment by supporting research into cheaper, longer-lasting fuel cells and increasing the production of hydrogen from domestic energy sources.

Top 9 Things You Didn’t Know about Carbon Fiber
The Energy Department’s Carbon Fiber Technology Facility at Oak Ridge National Laboratory provides clean energy companies and researchers with the opportunity to develop less expensive, better-performing carbon fiber materials and manufacturing processes. Pictured here is the carbon fiber conversion line with the in-line melt spinner. The melt-spinner will be used to produce new precursor fibers that will then be converted to carbon fiber. In collaboration with industrial partners, these fibers will be used to produce prototype composite parts for applications, such as automotive parts, wind turbine blades and thermal insulation. | Photo courtesy of Oak Ridge National Laboratory.
