18 C h a p t e r 3 3.1 Introduction As discussed in Chapter 2, the most common approaches for tracking alternative fuels are physical segregation, mass-balance, and book-and-claim. In addition, hybrid approaches combining these mechanisms are possible.

Detailed Discussion of tracking Mechanisms 19 Figure 8 shows the downstream movement of fuel from the fuel producer to the wing of the aircraft and the corresponding flow of information from the fuel producer to the blender, fuel transporter, fuel farm operator, airport fuel service provider, and the airlines. Gray areas indicate facilities on airport property; boxes with thicker lines indicate new infrastructure.

20 tracking alternative Jet Fuel The fuel farm operator takes receipt of the alternative fuel and any associated documentation, including the PoS form, if available. This information is then forwarded to the airline along with fuel inventory and consumption information.

22 tracking alternative Jet Fuel Roles and Responsibilities The main roles and responsibilities associated with implementing a tracking mechanism based on physical segregation are shown in Table 4. Some fuel farm stakeholders feel that physical tracking of the alternative fuel molecules should cease upon arrival of the fuel at the airport fuel farm.

Detailed Discussion of tracking Mechanisms 23 fuel at the airport fuel farm is not necessary from a safety or quality perspective since the fuel must conform to ASTM D1655 just like 100% conventional fuel, meaning that it is as safe as conventional fuel to be transported, stored, and dispensed using common airport fuel-farm infrastructure and equipment. 3.2.2 Mass-Balance Overview In the mass-balance approach, the fuel producer documents the physical mass (e.g., metric tons or volume convertible to mass)
|
From page 24... ...
24 tracking alternative Jet Fuel receives information about the mass (or volume convertible to mass) of alternative fuel received at that airport location but is no longer able to follow the molecules into the wings of its aircraft or those of any other aircraft operator receiving fuel from common fuel-farm tanks.

Detailed Discussion of tracking Mechanisms 25 preservation to a final dispensing tank is desired, the need to keep the fuel segregated until delivery favors fuel deliveries by truck, rail, or barge. Pipeline delivery of segregated fuel would be more difficult to achieve with identity preservation unless there were dedicated pipeline access to the airport from a refinery or terminal and the ability to physically ship and keep batches of alternative jet fuel separated.

Detailed Discussion of tracking Mechanisms 27 – Sustainability standard to which the alternative fuel complies; – Name of the third-party certification body; – Applicable on-product claim of sustainability; and – If desired, credits associated with the alternative fuel (e.g., RIN numbers)

28 tracking alternative Jet Fuel 3.2.3 Book-and-Claim Overview The defining element of the book-and-claim CoC method is the use of credits representing sustainability attributes. "Credit" relates to an accounting unit within a third-party–administered book-and-claim system.

Detailed Discussion of tracking Mechanisms 29 takes title to all the attributes of alternative fuel but without the obligation to take physical delivery of it. Instead, the fuel produced in this system is commingled with conventional fuel and is treated as such in the supply chain.

30 tracking alternative Jet Fuel – Alternative fuel pathway ID or production facility name; – Alternative fuel feedstock type and production process; – CoC method; and – Price. Alternatively, a PoS form with the sustainability information listed here can be attached to invoices regularly used for conventional jet fuel.

Detailed Discussion of tracking Mechanisms 31 local conditions. Beyond the control point, sustainability information is not expected to be transmitted further downstream with the alternative jet fuel.

From page 32... ...
32 tracking alternative Jet Fuel information from the third-party certification entity. The fuel and sustainability data are sent along the supply chain until they reach the control point, which is identical to what is done in the mass-balance CoC method.

Detailed Discussion of tracking Mechanisms 33 Infrastructure and Functional Elements The main infrastructure and functional elements required to implement this tracking mechanism are: 1. Fuel delivery mechanism: Up to the control point, similar conditions as for mass-balance apply; thus, unless the option of identity preservation to the control point is selected, massbalance batch shipments may use any fuel delivery mechanism.

From page 34... ...
34 tracking alternative Jet Fuel Data Items The main data elements necessary for implementing a hybrid tracking mechanism based on mass-balance and book-and-claim are: 1. Physical supply: For transportation of the alternative fuel to the control point, the same documentation used for mass-balance applies.

Detailed Discussion of tracking Mechanisms 35 – For blends of alternative fuel with conventional fuel: blend ratio, blending location and date, and any other relevant information so that the mass of the alternative fuel component can be computed; – Alternative fuel pathway ID or production facility name; and – Alternative fuel feedstock type and production process.
