Pathways to a Hydrogen Future

Hydrogen offers a possible solution to such problems as energy security, resource availability, and environmental concerns. The supply is unlimited. No one country or group of countries controls access to it. And it has the potential to be a carbon-free source, unless produced from hydrocarbons. While hydrogen is the most abundant element in nature, it must be stripped from either hydrocarbons (coal, oil, or natural gas) or water. The separated hydrogen can be used in fuel cells to generate electricity or can be combusted in modified engines. [Pg.10]

By stacking several fuel cells together, enough electricity can be generated to power a car or a bus. Fuel cells also can be used as stationary power and heat sources in residential and commercial settings. There are several hurdles to the commercial deployment of fuel cells in vehicles and for stationary sources cost (vehicle, fuel, and operating), fuel cell durability, safety issues, customer acceptance, and infrastructure development. [Pg.11]
