Introduction

As you learned in my presentation, hydrogen is the simplest of all elements, consisting of a single proton and an electron.  Hydrogen is useful as an energy source when in its gaseous diatomic form (H2).  It can be used as an energy source either when directly combusted or to drive electrochemical reactions.  It is most commonly used as a fuel source to propel space vehicles, and is now being viewed as a fuel for cars, trucks, buses, and even watercraft and airplanes. Unlike coal, oil, nuclear, solar, or wind, hydrogen is not a primary energy source.  Instead, it is a high-energy intermediate that can be generated by chemical reactions of organic molecules (including fossil fuels) or by electrical-based hydrolysis of water.  Vehicles that are powered by hydrogen do not emit carbon dioxide, as do conventional gasoline or diesel-powered vehicles.  Thus, if the hydrogen is generated by carbon-free processes like nuclear, solar, hydro, or wind, vehicles can be propelled using systems that do not emit greenhouse gasses.  Conversely, if the hydrogen is generated by processing of organic molecules - such as through coal gasification, carbon dioxide will be produced.  However, advocates argue that such carbon can be sequestered and placed deep into the ocean or underground where it would not act as a greenhouse gas.
