  2. What is hydrogen all about? • 9% of your body is made up of hydrogen • Greater than 90% of all matter is hydrogen • Hydrogen is 4 times lighter than air • Hydrogen can power a car with a non-polluting fuel and an electric motor • The combustion of hydrogen produces no carbon dioxide (CO2), particulate, or sulfur emissions. It can only produce nitrous oxide (NOX) emissions under some conditions. (DOE) • The amount of energy produced by hydrogen per unit weight of fuel is about 3 times the amount of energy contained in an equal weight of gasoline, and almost 7 times that of coal. (FSEC)

  3. Why hydrogen? To have an energy source be made from unlimited, renewable, & sustainable resources • Solve air pollution problems • Eliminate dependence on oil • Eliminate oil spills • Create domestic jobs

  4. Advantages • High safety • Self-ignition = 550 • vs gas at 228-501 • Disperses quickly in atmosphere • Cleans air • Completes combustion of the unburned hydrocarbons that surround us • Stores safely • Can be used to replace anything using fossil fuels unless carbon is specifically needed

  5. History of Hydrogen Hydrogen fuel cells power the shuttle's electrical systems, producing a clean byproduct—pure water, which the crew drinks. You can think of a fuel cell as a battery that is constantly replenished by adding fuel to it—it never loses its charge. • NASA 1st to experiment • Apollo & Gemini • By 1965 hydrogen fuel cells were standard equipment in spacecraft • Fuel cell price change • NASA used niobium plated with gold as a catalyst & expensive electrolyte • Today platinum is used as catalyst • $30,000 to $500

  6. -First Road Legal Hydrogen Car- • In the 1960s a man named Karl Kordesch used pressurized hydrogen gas to run a car, which was stored on the roof. The remodeled Austin reached a peak power of 20 kW and a maximum speed of 80 km/h. The range was 300 km. • The only requirement by the licensing board was a warning sign on the roof and a strict smoking prohibition in the passenger room.

  7. What hydrogen can do… • Fuel today’s internal combustion engine vehicles and tomorrow’s fuel-cell vehicles • Replace natural gas for heating and cooling homes and hot water heaters • Wind and hydroelectric plants can produce hydrogen and store energy during off-peak hours • Hydrogen production from hydrocarbons can produce carbon • This carbon can be made into carbon fiber which is 10 times the strength of steel….used for auto bodies

  8. Today • hydrogen fuel cell driven car manufactured by the Daimler-Chrysler company. • Prototype hydrogen fuel cell attached to a bicycle. • brake system powered by a fuel cell, the fuel source being hydrogen stored in a pressure tank

  9. Hydrogen in your car • Hydrogen Cycle • Hydrogen is infinitely recyclable and is converted back into water • The only waste in hydrogen powered cars

  10. Where does Hydrogen come from? You must make it…. • Electrolysis • using electricity to split water molecules into hydrogen and oxygen • Can do it anywhere • Reforming fossil fuels • Using a fuel processor or a reformer to split hydrocarbons into a useful hydrogen and a harmful carbon using heat • Used today with fossil fuels

  11. Electricity for electrolysis? • Nuclear Power • Hydroelectric dams • Solar power • Wind turbines • Geothermal power • Wave and tidal power • Co-generation • a sawmill might burn bark to create power, or a landfill might burn methane that the rotting trash produces

  12. 4 Ways to Make Hydrogen • ThermochemicalA steam reforming process is currently used to produce hydrogen from such fuels as natural gas, coal, methanol, or even gasoline. To draw on renewable energy sources, the gasification or pyrolysis of biomass—organic material—can be used to generate a fuel gas that can be reformed into hydrogen. • ElectrochemicalThe electrolysis of water produces hydrogen by passing an electrical current through it. • PhotoelectrochemicalThe photoelectrochemical (PEC) process produces hydrogen in one step, splitting water by illuminating a water-immersed semiconductor with sunlight. • PhotobiologicalPhotobiological systems generally use the natural photosynthetic activity of bacteria and green algae to produce hydrogen.
