As the nation's energy system evolves, hydrogen is expected to play a critical role in revolutionizing the grid, supporting the deployment of renewables by providing demand flexibility, as well as partially offsetting intermittency issues on the supply side.

U.S. demand for hydrogen could reach 17 million metric tons by 2030 and 63 million metric tons by 2050, roughly equivalent to 14 percent of final energy demand, according to a recent report.

The heart of a fuel cell is a device called a stack, which takes air and hydrogen and converts it to electricity. The stack extends the life cycle for on-road applications and accelerates the adoption of zero emission HFC electric vehicles (HFCVs).
