  1. Beyond Gasoline: Concept Cars

  2. Plug-In Hybrid (PHEV)

  3. EV • Electric Cars have not been successful. • Large heavy batteries • Short driving range • Slow refueling (recharging) process.

  4. GM EV-1 • Produced by GM from 1996-199.

  5. Tesla • Tesla Roadster may represent a new direction. • Uses new lighter batteries. • Expensive.

  6. GM Volt • Li-Ion batteries and a gasoline engine. • The gasoline engine will run a generator to recharge the batteries, but will not directly power the vehicle. (no gasoline motor)

  7. Fuel Cell Vehicles

  8. Internal Combustion Engine • Engine – 20% efficient • Only 20% of gasoline energy is converted to motion.

  9. Fuel Cells and the Hydrogen Economy • Fuels Cells use hydrogen to produce electrical energy. They do not burn hydrogen. • 2H2 +O2 2H2O + energy • Fuel cells could be used to power cars with hydrogen as the fuel. • Clean fuel

  10. Barriers to Hydrogen Cars • Still in development • Expensive • On-vehicle storage of hydrogen fuel • Availability of hydrogen fuel • Infrastructure

  11. Fuel Cells • In development stage. • Currently very expensive. • Are not a source of energy. • Hydrogen must be supplied.

  12. FuelCell Energy • Based in Danbury • Produces Direct Fuel Cells • Stationary not mobile • Distributed Generation Eastern is considering a 1 MW unit similar to this.

  13. UTC Power • Based in Hartford • Produces Fuel Cells • Both Stationary and mobile • Car engines are very expensive

  14. Connecticut Global Fuel Cell Center • Engineering research center at UConn

  15. Hydrogen Sources • Steam reforming of natural gas: CH4 +2H2O  CO2 + 4H2 • Electrolysis: 2H2O + energy 2H2+ O2

  16. Energy Source for Electrolyzer • Electrolysis requires energy. • Energy could come from Solar, Nuclear, or Wind. • In the short term, it would probably come from coal.

  17. Vehicle Carbon Emission(grams per mile)
