Vision – Easy Cogen
l l

80% total system efficiency Cogen is all-in-one. No separate air-to-water heat exchanger 125°F water. One million tons in place supplies about 110 gallons per minute Perfect for space heating (garages, offices, greenhouses) Pre-heat for higher temperature processes Landfill revenues increased. At $5.00 per MCF of natural gas, value of heat is about $165,000 per year per 1 million tons in place at 50% methane
Greenhouse applications are one possible cogen application

Vision - Solar Hybrid on Landfill Gas
l l l l l l

Solar power during the day LFG power at night Higher solar electric rates Solar buy down Turn landfills into solar parks Landfill revenues increased. Assuming 1 million tons in place, premium of 4?/kWh would generate about $150,000 additional annual revenue Super green credits

STM engine in series hybrid bus Compressed LFG for biogas fuel CARB 2003 NOx compliant Landfills as metro bus garages Sanitary vehicle refueling stations Landfill revenues increased. Assuming 1 million tons in place, 50% methane would have a comparable CNG price of about $3.00 per mcf based on today’s $5.00 per mcf for natural gas.
