  • CNG AND LNG: WHAT’S BEST FOR YOUR FLEET? Wisconsin Clean Cities and Clean Energy Webinar October 8, 2013 www.cleanenergyfuels.com cleanenergyfuels.com 1
  • Today’s Discussion Topics  The case for natural gas as a vehicle fuel  7 factors to consider in choosing the right fuel  CNG / LNG comparison  Application considerations  Infrastructure  Payback analysis cleanenergyfuels.com 2
  • CNG or LNG? It All Depends Natural Gas Heavy Duty Market cleanenergyfuels.com 3
  • Natural Gas: It’s Abundant, Domestic & Clean Natural Gas Supplied From US and Canada Imported 98%  200+ year supply  Renewable sources available   NGVs offer best solution to reducing foreign oil dependency < 1% of NG used for transportation in U.S. – 150,000 NGV's on road in U.S. today – 400,000 NG Trucks consuming 20,000 gallons/year each will use < 5% of our Nation’s Demand cleanenergyfuels.com 4
  • Energy Security: Who Provides Our Energy? Crude Oil & Refined Product Sources for US Consumption Natural Gas Sources for US Consumption Mexico 0.2% Others 19% US 28% OPEC 32% Canada 13% Others 3.3% Canada 16.4% US 80.0% Mexico 8% Powering the US Heavy-duty Truck and Bus fleet with natural gas could displace 3 billion gallons of diesel per day which is roughly more than half of the imports from OPEC and could shave $100 billion off the annual trade deficit at current oil prices.

  • Cost of Natural Gas versus Crude Oil $3.51 x 5.8 = $20.36 Natural Gas Equals $23.08 per Barrel of Oil (energy equivalent ) Commodities Market October 04, 2013 $109.46 Price as of 10.04.13 cleanenergyfuels.com 7
  • What Makes Up a Gallon of Fuel? DIESEL LNG 12% TAXES 19% DISTRIBUTION & MARKETING 11% REFINEMENT 28% CNG 16% 7% 6% 46% 58% COMMODITY 55% 20% 22% cleanenergyfuels.com 8
  • 7 Factors for an Informed Fuel Decision 1. Vehicle Type and Application – LNG / CNG differences and advantages 5. Fuel Cost – Savings vs. diesel and gasoline 2. Duty Cycle – Range, speed, idle time 6. Fleet Fueling Needs – Refueling cycles 3. Combined Weight – Payload, storage tank weight 7. 4. Hours of Service – Drive, idle, down time Fueling Infrastructure – Availability on your routes cleanenergyfuels.com 9
  • CNG / LNG – the Distinction   CNG and LNG are simply two different ways natural gas is stored There is no such thing as an “LNG engine” or a “CNG engine” – It’s not engine type that differentiates LNG and CNG, it’s how the fuel is stored and supplied to the engine – Both are delivered to the engine as a gas cleanenergyfuels.com 10
  • LNG / CNG – Energy Density  Relative to one gallon of diesel: – LNG = 1.7 DGE – CNG = 3.8 DGE  7 6 Energy density is an important factor you need to consider when choosing a natural gas vehicle 5 CNG 4 3 2 1 LNG DIESEL 0 One DGE cleanenergyfuels.com 11
  • CNG and LNG FUELING CONSIDERATIONS cleanenergyfuels.com 12
  • Compressed Natural Gas (CNG) Basics  Light, medium, and some heavy duty applications – <50 DGE/Truck/Day   NG delivered by gas co pipeline to fueling station Dried, compressed & stored at 4,500 psi and dispensed to vehicle at 3,600 psi  Dispensed at similar speed (gpm) to gasoline  Stored in cylinders onboard the vehicle cleanenergyfuels.com 13
  • CNG Time Fill  Complete fill because we can dissipate heat – Three to six hour fill period – Increase Range  Lowest cost installation – Best value cleanenergyfuels.com 14
  • CNG Fast Fill  Large capital investment – >2X compared to LNG – $5+ million for four lanes dispensing at 12 gpm at the same time – 0.5 acre for CNG compound & electrical equipment  High heat gain during fueling – >30% loss of storage  Industrial Utility Services – NG, both pressure & flow – >2 MW electrical demand cleanenergyfuels.com 15
  • CNG Station Reality  The majority are not “truck friendly”! cleanenergyfuels.com 16
  • Liquefied Natural Gas (LNG) Basics  Pipeline gas cooled to -260F  Produced at LNG plants  Delivered in trailers to fuel stations  Rapid fueling at 12+ DGE per minute  Ideal for heavy duty vehicles – Storage volume is half of CNG – System weight is less than CNG – Consistent fuel range vs. CNG cleanenergyfuels.com 17
  • LNG Fast Fill Fueling  Transparent to diesel fueling – Typically, not site constrained  LNG storage reduces truck weight & increases range compared to heavier/multiple CNG HP vessels cleanenergyfuels.com 18
  • CNG / LNG APPLICATIONS cleanenergyfuels.com 19
  • Consider Your Application  Choosing between LNG and CNG is really about the spectrum - at either end the choice is relatively fixed light-duty automotive & industrial bus & vocational trucks heavy-haul transport CNG LNG cleanenergyfuels.com 20
  • Fueling Options Widen in the Middle bus &vocational trucks CNG  CNG is a good option for:  Refuse and transit using fast or time fill  Medium duty applications < 300 miles per fill LNG  LNG is a good option for:  Long driving range requirements  8.9L to 12L engines hauling up to 80,000 lbs cleanenergyfuels.com 21
  • Your Fleet’s Duty Cycle is Important  Helps you evaluate: – How much energy your vehicles require – How often vehicles will need to be refueled  Consider: – Number of hours a vehicle is in use per day – Number of hours a vehicle is driven per day 7 DAYS LNG NEEDS TO BE USED WITHIN 7 DAYS TO AVOID TANK VENTING cleanenergyfuels.com 22
  • Consider Your Fleet’s Fueling Needs  Return to base fleets are good candidates for CNG – You can install infrastructure to fuel at base using fast fill or time fill  Time fill is an attractive fueling method that is less costly and complex – Does not require a storage system – Compressor is smaller and less expensive – Attractive option for fleets that are idle overnight, like refuse and school buses  Fleets that operate around the clock need a fast fill option – Public or private cleanenergyfuels.com 23
  • Payload and Storage Tank Weight Count  The weight difference between CNG and LNG is dependent on the amount of fuel being stored Diesel 15 Gal. LNG CNG 26 Gal. 58 Gal. cleanenergyfuels.com 24
  • Ask Yourself…  How much tank weight can you afford? – A Westport LNG tank providing 60 DGE’s of storage capacity weighs 1,100 lbs when full – CNG tank packages providing 60 DGE of fast fill storage capacity typically weighs 1,600 lbs  How much space will the tank require? – LNG tanks are typically mounted with standard diesel tank brackets – CNG pressure vessels are typically packaged in steel racks cleanenergyfuels.com 25
  • CNG Advantages  Greater infrastructure than LNG – Light and medium duty  Considerations   Simple fuel systems – Easy to fuel like gasoline    No diesel, DPF, or SCR to manage (SI engines) Gas/Vapor instead of cryogenic  Less CNG infrastructure for trucks than LNG Fuel storage tanks – Heat of compression – Weight of storage tanks – Range limitations Limited to 9L and 12L spark ignited engines – Cummins 15L in 2016 No fuel loss if parked for an extended period of time cleanenergyfuels.com 26
  • LNG Advantages  Greater fuel density/volume – Greater range then CNG – Lower weight of storage  Faster fueling – Fuels like diesel – No impact to HOS   Growing “Truck Friendly” infrastructure No diesel, DPF, or SCR to manage (SI engines) Considerations     Cryogenic tanks Special handling when fueling Pressure and temperature management of fuel to engine Potential boil off (use it or lose it) if vehicles are parked for extended period cleanenergyfuels.com 27
  • NATURAL GAS FUELING INFRASTRUCTURE cleanenergyfuels.com 28
  • Clean Energy Vertically Integrated Fuel Partner cleanenergyfuels.com 29
  • North American Infrastructure  CNG is more publicly available than LNG  CNG stations must be near a pipeline network – Concentrated in California, New York, Utah, Oklahoma, Arizona, Texas, Colorado   LNG can be hauled long distances from the liquefier while remaining economical About 150 LNG stations would provide fueling coverage along all of the major interstate trucking routes – At 250 mile intervals cleanenergyfuels.com 30
