Pipeline-Quality Biogas Benefits
• California has 1.7 million cows in 2,100 dairies– 75% in Northern California– 50% in San Joaquin Valley
• Methane normally escapes to atmosphere from open lagoons at dairies
• Methane and other reactive organic gases (ROGs) cause air non-attainment status for San Joaquin Valley
• Methane is 21 times as potent as CO2 as a Greenhouse Gas
• Central generating plants are cleaner and more efficient than small, distributed generators that would be used at dairies
• Pipeline transport to cleanest, most efficient central plant cleans up valley air and destroys a potent greenhouse gas
• PG&E will produce more renewable energy without the need for electric transmission reinforcements

Promising Technology: Great Point Energy’s Catalytic Methanation
• Claims to produce $2.50-$3.50/MMbtu methane from coal without subsidies or tax credits
• Key to process is proprietary catalyst that allows low temperature gasification/methanation process with steam
– Large avoided capital infrastructure
– Significant reduction in operating costs from operating at lower temperatures
– Lower maintenance requirements
• Demo project at O’Hare airport
• Investor backing includes Draper Firsher Jurvelson, Kleiner Perkins
• Management team includes serial entrepreneurs, gasification and refining veterans
