USAF Alternative Fuel Goals

Early 2011 Certification Goal

Certify entire AF Fleet to use a 50/50 SynFuel blend

2016 Acquisition Goal

Cost competitively acquire 50% of Air Force's domestic aviation fuel requirement via alternative fuel blends in which the alternative

component is derived from domestic sources produced in a manner that is greener than fuels produced from conventional

petroleum

400 million gallons of “Alternative” Fuel3

FT-Blend Assessment Conclusions

No materials compatibility issues determined Engine test performance & operability equivalent to

JP-8 baseline No in-flight performance or operability differences

noted by aircrews No impacts to toxicity or infrastructure Most USAF systems tested; all USAF systems certified ASTM specification approved authorizing FT-blend for

all commercially certified systems – 1 Sep 09 JP-8 Specification (MIL-DTL-83133G) revised

authorizing FT-blend for all USAF systems - 30 Apr 10 Program complete

HRJ-Blend Certification Status

Hydro-Processed Renewable Jet (HRJ) Blend “Pathfinder” Strategy – Evaluate only fleet-wide representative,

or most challenging systems Certify remaining fleet by similarity

A-10, F-15, C-17, F-16, MQ-9, RQ-4, C-130 & F-22 demonstrated HRJ blend ops

No significant performance of functional differences noted relative to JP-8

90% of the fleet certified Certification activities on-track for FY13 completion Field Service Evaluation completed for the F-16 to evaluate

longer term impacts of HRJ-blend use (~100Kgal of blend)

Alt Fuels CertificationATJ Strategy

Phase 1 – Approved Feasibility Demonstration Validate ATJ as viable pathway; bridge “producibility” gap

Perform materials & sub-system evaluationsDedicated engine test completedA-10 aircraft flight test scheduled for Jun 2012

Phase 2 – Follow up w/accelerated USAF certification

Decision to proceed depends on success of Phase 1 Similar to HRJ effort Dedicated “Pathfinders” & engine testing Majority of fleet by similarity

Summary JP-8/SPK (Fischer Tropsch) Certification Program

FT fuel blend performs just like JP-8 MIL-DTL-83133G revision allows unrestricted usage for USAF

“Drop-in” primary fuel for aircraft, engines, GSE, & infrastructure

Biomass-Derived Fuel (HRJ) Program A-10, F-15, C-17, F-16, MQ-9, RQ-4, C-130 & F-22 successfully

demonstrated operations 90% of the fleet fully certified HRJ fuel blend performs just like JP-8

Alcohol-to-Jet (ATJ) Program- Feasibility Demo approved; FY11/12 effort underway

On Track to Meet USAF Synthetic Fuel Goals

Gaining efficiencies through interaction with DoD, inter-agency, industry, academia, and allied efforts

Contact Issue

Individual Producers Contacting Bases Bases do not have authority to contract fuel

purchases. DLA Energy is the Executive Agency for purchasing fuel for USAF use.
