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” Fuel

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)

ATJ Strategy
 Phase 1 – Approved Feasibility Demonstration

Validate ATJ as viable pathway; bridge “producibility” gap
 Perform materials & sub-system evaluations
 Dedicated engine test completed
 A-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.
