  1. Advanced Energy ProductionSt. Joseph Hospital 2010 Sustainable Solutions Research TeamJune 2010

  2. Project Objective • Shall St. Joseph Hospital generate energy? • Distributed Generation – what is it? • Benefits of Distributed Generation to the Hospital • 3 Systems Comparison, Case Study for each: • Fuel Cell with Combined Heat and Power • Combined Heat and Power • Photovoltaic • Conclusion

  3. Distributed Generation From PSE: 6% BTU loss 65% BTU loss Your Own System: 25% BTU loss

  4. Benefits to Hospital • Minimize risk associated with price volatility • Reliable power • Reductions in energy cost improve operating margins • Moves PeaceHealth towards a cleaner hospital • Good corporate citizenship

  5. Energy Systems • Fuel Cell CHP • Combined Heat and Power using Hydrogen and Natural Gas • Combined Heat and Power • A Power Plant – uses Natural Gas • Photovoltaic – It’s Solar Power!

  6. Fuel Cell • It’s Combined Heat and Power! • Uses Natural Gas and Hydrogen • Clean electro-chemical process • Hydrogen produced by subjecting hydrocarbon (natural gas) to steam under pressure • Emissions are low

  7. Fuel Cell Case Study • St. Francis Hospital and Medical Center, Hanford CT • 200 kW of electricity • $7,000 per kW • Installed Cost: $1.4 M • 22.3 year payback

  8. Combined Heat and Power • Simultaneous production of electricity and heat • Reliable power • Waste heat recovery for heating, cooling, dehumidification

  9. CHP Case Study • Resurrection Medical Center, Chicago • (2) 725 kW natural gas engine generators • $1,200 per kW • Installed Cost: $1.74 M • 14.5 year payback

  10. Photovoltaic System • It’s Solar Power! • East Tower installation will produce 147 kW • Passive system • No moving parts • 25 year warranty available • Wide usage in Hospitals

  11. St. Joseph Hospital East Tower EAST TOWER

  12. Photovoltaic Case Study • Jerry L. Pettis Memorial Medical Center, Loma Linda CA • 309 kW • $6,000 per kW • Installed Cost: $1.85 M • 30.9 year payback

  13. Costs and Emissions

  14. Conclusions
