Transcript

  • 1. Biogas to Vehicle CNG Wisconsin Clean Cities November 5, 2013
  • 2. Biogas/Vehicle Fuel Benefits • “Home grown” Fuels – Lock in your future fuel cost long term • Green Fuel- RNG has the smallest carbon footprint of any commercial vehicle fuel • Complies with CNG fuel specs and engine warranties 2
  • 3. BioCNG Is…. A Patent pending system to convert biogas from an anaerobic digester or a landfill to a gaseous vehicle fuel.
  • 4. CNG Terms and Definitions  CNG - Compressed Natural Gas  LNG - Liquid Natural Gas  RNG - Renewable Natural Gas (BioCNG™)  GGE - Gasoline Gallon Equivalent, 116,000 BTU/Gal  DGE - Diesel Gallon Equivalent, 130,000 BTU/Gal  Biogas - Methane (CH4) and carbon dioxide (CO2) produced from the breakdown of waste by bacteria in wastewater treatment facilities and landfills  RIN - A Renewable Identification Number is a serial number assigned to a batch of biofuel for the purpose of tracking its production, use, and trading
  • 5. Things to Consider  CNG vehicles on site or in future budget?     How many vehicles? What type of vehicles? How often do they need to fill up? Time or fast fill?  Is suitable biogas available?  Is natural gas available on site?  Existing infrastructure  CNG infrastructure  Biogas Conditioning System

  • 29. The CNG Revolution • Gasoline and diesel costs continue to rise • Natural gas is abundant and has a lower unit energy cost than petroleum fuels. • Fleets are converting to CNG for cost savings • Natural Gas / CNG will play a role in our nation’s energy security and independence • CNG has environmental benefits over Gasoline and Diesel 31
  • 30. What is CNG? • Natural gas compressed to 3,000-5,000 psi • CNG is used worldwide as a vehicle fuel – 15,000,000 vehicles worldwide – Approx. 200,000 vehicles in US growing rapidly – Powers small and large vehicles (scooters to semis) • Renewable Natural Gas (RNG) fuel is from renewable biogas sources – Landfills, WWTP digesters, Organic waste /food waste digesters, dairy/ agricultural digesters 32
  • 31. Today’s Presentation • CNG overview • Biogas/vehicle fuel opportunities • BioCNG in Wisconsin 33
  • 32. Efficiency of BioCNG to Convert Methane into Vehicle Fuel • Methane efficiency of the BioCNG system varies depending on the concentration of methane the raw biogas. • Methane not converted to vehicle fuel is routed with the carbon dioxide waste gas to be destroyed in a boiler, flare or micro turbine. • If the waste gas is routed to a boiler, micro turbine, or other recovery system the methane efficiency may approach 100%.
