Hythane - Low Carbon Fuels Conference Series

Hythane ® – Facilitating theTransition to Hydrogen Proven technology 5 - 7 % by Energy of H 2 /Natural gas blend (20% by volume) Up to 50% NOx emission reductions Piggybacks on existing CNG/LNG infrastructure Provides tremendous strategic flexibility: Can be calibratedto reduce NOx by up to 30% without decrease in range orincrease range up to 10% with no decrease in NOx Reduces emissions of greenhouse gases by 7% Roll out of Hythane ® infrastructure (NG reformation &blending) most cost effective 1 st step toward Hydrogeninfrastructure development. Clean H 2 Enriched NG Fuel is available TODAY!

Hythane ® LeverageHHNOMost Cost-effective Use of H 2

What is the best use of 7%Hydrogen Energy?Case 1: Convert 7 CNG Vehicles to HydrogenHydrogen VehicleCNG VehicleHythane VehicleResult: 7% NOx reduction, 7% hydrogen energyCase 2: Convert 100 CNG Vehicles to Hythane ®Result: 50% NOx reduction, 7% hydrogen energy

Hythane ® and ZBus MandateHythane ® - only technology that can deliver on most ofCARB’s ZBus goals today Proven technology is ready for implementation today Hythane ® reduces NOx emissions by 50% over NGbaseline Reduce fleet emissions by NOx 50% upon implementation Utilizes existing NG infrastructure and adds hydrogen withminimum impact Best known available leverage of hydrogen

Hythane ® and Heavy Duty ServiceHythane® - Best available technology to deliver extended positivebenefits on every technologyProven technology for Heavy Duty Lean Burn Engines Reduce fleet NOx emissions by 50% upon implementation Lowest cost retrofit available Impartial to engine Make and ModelBenefits in Dual-fuel applications when used in place of Natural gas greatly reduced HC & NOx emissions at all load levels increased efficiency compared to NG fumigation extension of knock limited power with pilot injection of diesel reduced consumption of diesel fuel because of 2) and 3) above

Hythane ® and Heavy Duty Service Continued Stoichiometric Engines with EGR and 3-Way Cat Emissions with the catalyst and stoichiometric operation will beextremely low with either NG or Hythane(any improvements may be academic at these low levels) Hythane can still improve efficiency by about 10% to 15%by enabling more EGR tolerance, just like extending the lean limit.

Existing Natural GasInfrastructure Eases TransitionVia Time to Market No longer experimental - over 3 million NGVs on the globe nowEasy Transition Near-term Objective Existing CNG vehicles can easily be converted to operate on Hythane ®Hythane ® can be deployed at existing CNG & LCNG stationsCustomer base already accustomed to using a gaseous fuel Medium-term Objective Hythane Company is currently developing LNG/Cryogenic Hythane ®LNG/Cryogenic Hythane ® to be deployed at existing LNG stations

Hythane ®can Accelerate theIntroduction of Hydrogen into Fleet Use Most cost effective use of Hydrogen that isavailable today Infrastructure that builds on and co-exists withNatural Gas stations Infrastructure that will continue to be useful intothe Hydrogen economy Pre-Approval of “Hythane ®” as means to fulfill theZBus requirements
