DOE projects the demand for oil in the U.S. to increase by nearly 50% by 2025. Petroleum imports already supply more than 55% of U.S. domestic needs, and those imports are projected to increase to more than 68% by 2025. This dilemma has driven the U.S. hydrogen fuel initiative aimed at reversing America's growing dependence on foreign oil by developing the technology for commercially viable hydrogen-powered fuel cells to power cars and trucks, as well as homes and businesses with no pollution or greenhouse gases. Funding for the hydrogen fuel initiative over the next 5 years is targeted at $1.7 billion to develop the technologies and infrastructure to produce, store, and distribute hydrogen for use in fuel cell vehicles and electricity generation.
As one might expect, the projected success of and the estimated time to reach commercialization of hydrogen as the primary fuel source varies considerably.
