Advancing Utilization of Manure Methane Digester on Haubenschild Dairy Farm

  1. 1. Advancing Utilization of Manure Methane Digester Funding for this project was recommended by the Legislative Commission on Minnesota Resources from the Minnesota Environment and Natural Resources Trust Fund ($204, 375)
  2. 2. Haubenschild Dairy Farm Energy Production Princeton, Minnesota Milk Production + Crop Production + Electrical Production + Future Hydrogen Production = Farm Income Diversification
  3. 3. Challenges to using biogas for a fuel cell Hydrogen sulfide removal Initial concentration 3000-5000 ppm Need concentration < 25 ppb Moisture removal Need dry gas Dewpoint < -30 degrees Celsius Carbon dioxide removal Need concentration < 5 ppm
  4. 4. Emissions from Haubenschild Generator Compared to Plug Power™ Proton Exchange Membrane (PEM) Fuel Cell Fuel Cell Engine Generator CO ( <1 ppmv) 0.014 g/kWh ( 799ppmv) 4.18 g/kWh NOx (<1 ppmv) <.0023 g/kWh (2963 ppmv) 25.5 g/kWh (277 ppmv) 3.34 g/kWh SOX (<1 ppmv) <0.030 g/kWh (2.46 %) 53 g/kWh C X HY (<1%) 14.5 g/kWh
