4/14/2017November 20, 2008 Participants + + Orange Co. Sanitation District (OCSD) ---Host site/utilities/digester gas U.S. Department of Energy (DOE) – Cost sharing Air Products and Chemicals (APCI) – Engineering/Operation Fuel Cell Energy (FCE) – Fuel Cell Power Plant National Fuel Cell Research Center (UCI) – Data acquisition/validation South Coast Air Quality Management District (SCAQMD) – Grant funding

8 12-Month Study Determine quantity and quality of hydrogen
Maximize electricity and hydrogen Optimize process efficiency Establish a hydrogen fueling station Analyze data to determine economic and environmental benefits

9 Environmental Goals Create an alternative to gasoline
Governor’s “Hydrogen Highway” Emissions reduction from digester gas combustion Clean / renewable energy source


11 Renewable H2 Energy Station Vision
Treatment Plant Heat Power Fuel Cell Biogas Heat Solids Treatment Assume 1.5 – 1.7 Cars per Household (US = 1.7, Britain = 1.5) The system we are demonstrating could easily support a 100 home community with electricity and hydrogen for fueling. Fuel Cell Energy’s larger product the DFC-1500 could support a 500 home community. One thing you should note about this program is that we are harnassing the knowledge and efficiencies that reside in elements of existing technology. There is no fundamental novel advance in any one technology required but rather a combining of technologies, ideas, and people in a way that hopefully results in a technological breakthrough. Robert Fulton combined a steam engine with a sailing ship to radically alter global commerce. He didn’t invent the steamship so much as bring together the right technical components, business ideas, people to make it work. We haven’t invented the coproduction system but I do believe that we are bringing together the right technologies, the right people, and the right experiences that like the way Robert Fulton radically altered global commerce, we are hoping to radically alter global energy by advancing the development of a viable solution for hydrogen fueling infrastructure.

13 Digester Gas Fed DFC® Power Plants Sierra Nevada Brewery, CA
Wastewater Treatment, Santa Barbara, CA Sierra Nevada Brewery, CA Kirin Brewery, Japan This is a photo of two power plants in California. As you can see, they don’t take up a lot of room but they are kicking out a total of 500 kWs of power. They are using what’s called anaerobic digester gas (produced when wastewater is treated) to generate the electricity that Santa Barbara uses to run the plant and the excess can be sold back to the electric company.

14 Fuel Cells can contribute to reducing targeted emissions
Industrial Environmental Coalition of Orange County 4/14/2017November 20, 2008 Fuel Cells can contribute to reducing targeted emissions Target Reduction Fuel Cell Reduction VOCs – 250 to 30 ppm (88%) VOC – ND NOx – 40 to 11 ppm (73%) NOx – 0.3 ppm CO – 600 to 200 ppm (67%) CO – 10 ppm SCAQMD Rule on CGS 14
