2. What is this hydrogen you speak of? Most basic element One proton & one electron Most plentiful element Natural is never by itself Always bonded to other elements (Ex. H2O) P N E Hydrogen Atom

3. How does hydrogen work for energy? Must be separated from other elements Two common processes: Steam Reforming Electrolysis

4. Steam Reformation Most commonly used Least Expensive Makes 95% of Hydrogen Separates hydrogen from carbon in Methane Creates greenhouse gases Developing methods Expensive Separates hydrogen from oxygen in water Emission free Two Common Processes Electrolysis

5. Where is it stored and how is it used? Stored in fuel cells Expensive to build Very Efficient Hydrogen can be used in a variety of ways Cars Household Electricity Space Shuttles

6. Though hydrogen powered cars are not ready for primetime for consumers yet, many manufacturers are showing off their concept cars and prototypes to get consumers excited about the future. Hydrogen Powered Cars Photo Credit: http://www.mwerks.com/artman/publish/bmw_ne ws/printer_845.shtml

7. NASA has used liquid hydrogen since the 1970s to propel the space shuttle and other rockets into orbit. Hydrogen fuel cells power the shuttle's electrical systems, producing a clean byproduct - pure water, which the crew drinks.

8. Pros Widely Available Only Emission is Water Twice as Efficient as Gasoline Cheapest Source is Natural Gas, a Nonrenewable No Standardized Method of Storage Still in Experimental Stage Pros and Cons of Hydrogen Cons
