  1. Dane County CNG Efforts April 25, 2013 John Welch, PE Solid Waste Manager Dane County

  2. Dane County’s CNG History • Experience with landfill gas and digesters • Pipeline quality gas project • Continued to evaluate options • Pilot bioCNG project • Funding from SEO and WCTP • CNG station, bioCNG station, and vehicles

  3. What’s Driving Fleet Conversions • Fuel Savings • Proven Technology – engines • Emissions regulations • Capital Cost • O&M Costs • Payload • Available Fuel Stations (Chicken & Egg) • Contract Requirements • Image / Marketing

  4. Environmental Benefits http://www.arb.ca.gov/fuels/lcfs/121409lcfs_lutables.pdf

  5. Vehicles • 24 vehicles in fleet • All Dual-fuel • F150s, F250s, F350s, Ford Fusion, Transit Connect • 7 Departments • Will add 15-20 in 2013 • Some dedicated CNG • Plow Trucks, van, pickups, passenger car • Conversion cost • $10,000 - $12,000 each

  6. Vehicle Conversion Options • Dedicated, bi-fuel, or dual fuel • Available options & intended use • Range • Typical route (return to shop?) • Direct from manufacturer or OEM conversion • Available models • Warranty / service • Cost

  7. Vehicle ROI • Variables • Initial Conversion Cost • Dedicated or Dual-fuel • Miles driven per year • MPG • Fuel Savings ~$2.00/gal

  10. Dane County’s CNG Station • Natural gas only • 2 hoses • Fast-fill • 100 GGE storage • 30 GGE/hr from compressor • Funding • ~$280,000 grant from SEO and WCTP • ~$42,000 from County funds

  11. Fueling Station ROI Results *Based on 1600-2000 GGE/month

  12. What if we increase CNG Usage?

  13. Pilot System Biogas from landfill 5 GGE/hr 1 hose Fast-fill 40 GGE storage Funding All Dane County New System Biogas from landfill 10 GGE/hr Pipeline gas backup 2 fast-fill hoses 4 slow-fill hoses 200 GGE storage Funding $150,000 from SEO Dane County’s BioCNG Station

  14. Old System New System

  15. BioCNG Differences • Extra Capitol • Extra O&M Costs • Cheaper Gas? • Other revenue potential for gas? • RINs

  16. CNG vs BioCNG ROI Results *2000 GGE/month. Breaks even at ~4000-5000 GGE/month

  17. Hurdles • Vehicle Procurement • EPA Certifications • Limited options • Delays • Fueling Stations • Training • Infrastructure & vehicle maintenance • Learning Curve • Permitting, codes, regulatory agencies, taxes, maintenance, etc
