  • This is about the size needed for the 200 to 600 cow operations specifically designed for the MA farms. This is a 300K gallon tank, with organics arriving on the site in a 6K gallon tanker truck, pumped into a storage tank, and blended with the animal waste. No organic sees the light of day. Permits are under the composting rules of the DEP. There also need to be positive rules from the net metering — allowing for the new virtual metering interpretation where behind the meter and for the excess the farms receive the retail price. The MA Green Communities Act passed in July 2008 provides for this. The contemplated revisions to the MA composting rules will also recognize digesters as a form capable of taking organic waste onto the farm in the quantities needed.
  • We welcome comments and suggestions.

    5. 6. Anaerobic Digestion – GHG Reduction and Energy <ul><li>Combustion of Methane: </li></ul><ul><li>CH 4 + 2O 2  CO 2 + 2H 2 O </li></ul><ul><li>Transforms methane (Global Warming Potential of 21-25) to carbon dioxide (GWP of 1) </li></ul><ul><li>Replaces fossil fuel use for electricity generation and local heating </li></ul>300kW GenSet 92.5% Uptime X = 2,430,900kWh per year 2,430,900kWh per year / 7,620 kWh per household = 319 Renewable Massachusetts Households per AD
    6. 7. Benefits of Anaerobic Digestion Deployment Host Farm - Reduced energy cost (electricity and heat) - Reduced manure odor/pathogen load w/ increased inorganic nitrogen content - Recycled nutrients for field fertilization - Animal bedding - New Farm Income Local Community - Renewable power produced for export at high efficiency - Preservation and creation of local jobs - Reduced manure spreading odor - Recycled nutrients available for local agriculture - Preservation of agricultural heritage The Commonwealth - Diversion of organic materials from landfills - Helps meet state renewable power goals - Attracts clean tech technology development Our World Community - Reduces greenhouse gas emissions
    7. 8. Challenges – Juggling Many Parties Farms Organics Energy Funding Utilities Attributes Workable net metering or feed-in tariff Sale of excess electricity at close to retail Short turn around for equity Not bundled with energy Cash Market Scrape facilities Use, or willing to switch to organic bedding Truck Access (25 ton loads) 3 phase power service Existing heat demand and waste heat user 350-1,000 cows, or ability to aggregate Existing waste hauler Allowances and incentives for organic waste diversion Market size and current Cost of disposal Fields with slight or no slope Desire to control odor or environmental challenge Proximity Grant Programs Equipment/ Construction Equity and Loans Interconnection requirement Bonds Equity Sources Long term utility contract Co-products Organic fertilizer market Soil amendment market
