  1. The Home Energy Station - More than a distributed Hydrogen refueling solution Dr. Jim Winkelman Plug Power Inc. International Conference on Automotive Technology November 13-14, 2008 Istanbul, Turkey

  2. Hydrogen Refueling Infrastructure The Energy Distribution System in North America Consists of Primarily Three Networks • Gasoline/Diesel • Electricity • Natural Gas

  3. Electricity – Electrolysis (solar, wind, nuclear, …) Fuel Cell Vehicle Hydrogen Refueling Station Natural gas - Reforming Hydrogen Infrastructure Multiple manufacturing paths for Hydrogen

  4. Transportation Home Energy Station Residential Family Energy Needs

  5. Design Concept Home-size combined system, which provides Hydrogen to FCV while supplying Electricity and Heat to household

  6. Specifications Specification Natural Gas 13 kW 1455mm 50 H2 Flow Rate SLM H2 Purity SAE J2719 Eq. Filling Pressure 35 MPaG Specification Max Power Output kW 4 Start Up Time 10 min 705mm 1330mm 54 dB Noise H2 Mode 40 % Efficiency Power Mode 30 %

  7. ～ ～ ～ System Flow Inverter ～ Electricity Grid Heating Reforming PSA FCV DMS (FC or H2 Pump) Natural Gas Hydrogen Compressor

  8. Operation Mode Typical Operation Pattern Power Mode 12 h H2 Mode 6 h Operation Thermal Demand Time 6 12 18 24 6

  9. ～ ～ ～ Operation Mode Inverter ～ Electricity Grid Heating Reforming PSA FCV DMS (H2 Pump) Natural Gas Hydrogen Compressor Hydrogen Mode ➤Generating Hydrogen ➤Charge Compressed H2 to FCV ➤Perform Overnight Fill

  10. ～ ～ ～ Operation Mode Inverter ～ Electricity Grid Heating Reforming PSA FCV DMS (Fuel Cell) Natural Gas Hydrogen Compressor Power Mode ➤Generating Electricity ➤Export Electricity to Grid

  11. Dual Mode Stack Fuel Cell Technology e- Exhaust ➤ Fuel Cell and H2 Pump Combined stack ➤ Hydrogen purify and pressurize (H2 Pump) Anode Reformate H+ Air Cathode Specification Max Power 5.5 kW Hydrogen Pump Exhaust H2 Flow Rate 65 SLM MPaG Discharge Press. 0.8 Anode Power Supply Reformate H+ H2.H2O Cathode

  12. Typical Customer in the LA Area • Electricity usage – 15,230 kWhr/year • Heat usage – 13,827 kWhr/year • Vehicle - 4 cylinder “C/D” class • 24,000 kilometers/year • 1924 liters/year

  13. How Does One Compare Systems? • Today • Centralized Generation • Conventional Car • Furnace • Hot Water Heater • Tomorrow • Decentralized Generation • Fuel Cell Car • Combined Heat and • Power

  14. Fuel Utilization Overall Efficiency Common Ground Minimize Waste

  15. Fuel Utilization ~10% Increase in Utilization The Home Energy Station provides about a 10% improvement in fuel utilizationper year

  16. CO2 Emissions ~28% Decrease in CO2 The Home Energy Station provides a 28% reduction in CO2 per year

  17. Conclusion Home Energy Station Concept • Offers a convenient Hydrogen refueling means • for FCV at home • Contribute to the deployment of FCVs • Reduction of CO2 emissions • Save on energy costs Ongoing Validation Test • Ongoing at Torrance, CA • Provides real world operational experience • Refueling for FCV and supplying electricity • to building
