APPENDIX J Transportation and Logistics of Alternative Fuels Drop-in alternative jet fuels will be able to share the same transportation, storage, and han- dling infrastructure as conventional jet fuel. Thus, from a logistical point of view, there should be no difference between alternative and conventional jet fuel. However, since jet fuel infrastruc- ture is typically a shared resource serving many customers, all users must agree to the alternative jet fuel being present in the distribution chain. The main options for transporting alternative or conventional jet fuel to the airport are listed in the following: Pipeline: This is the most cost-effective option for transporting the finished fuel, especially if the processing plant and the airport already have pipeline access. Rail or barge: Rail or barges are the next most cost-effective options for transporting finished fuel. As in the case of pipelines, the maximum benefit is achieved if both the processing plant and the airport already have access to rail or barges. Truck: This is the least cost-effective option for transporting the finished fuel; however, truck transportation provides the most flexibility because it does not require the existence of expen- sive infrastructure such as pipelines or railways. Thus, in the absence of pipelines or railways, truck transportation may be the most practical option. One important consideration that should be highlighted is the potential need for blending infrastructure. Since thus far alternative jet fuels have only been certified as a blend (up to 50% in the case of FT), there will have to be a place in the supply chain, prior to reaching the wing of the aircraft, where alternative and petroleum-based jet fuels are blended. This will most likely consist of separate storage for conventional jet fuel, alternative jet fuel, and the blend. Logical locations for blending facilities are points along the supply chain where alternative and conven- tional fuel would intersect. For example, injection points at pipelines that transport jet fuel and airport fuel farms are likely locations. 111
