As President Biden kicks off a sequence of occasions centered on rural funding, 70 business leaders masking practically the whole provide chain for sustainable aviation gas (SAF) – together with main airways – known as on the Biden Administration to unleash progress in de-carbonizing aviation by recognizing the U.S. Division of Power’s Argonne GREET mannequin underneath Part 40B(e) of the Inflation Discount Act.
In an open letter to Treasury Secretary Janet Yellen, the authors clarify that “our skill to draw funding and construct out U.S. SAF capability will rely on how this system determines credit score eligibility and valuation.” The default mannequin for evaluating SAF misses key points of de-carbonization, together with “local weather good and regenerative feedstock practices” supported by the IRA.
Fortuitously, the IRA explicitly permits for the usage of “any comparable methodology” for figuring out SAF credit score eligibility and valuation. Because the letter explains, the Argonne GREET mannequin “incorporates the most recent biorefining and feedstock manufacturing efficiencies.” It accounts for “each facet of the ‘full gas lifecycle’” — from “land use adjustments” to “all levels of gas and feedstock manufacturing and distribution.” Argonne GREET clearly meets statutory necessities, and in contrast to any new method that will invite additional delay, it’s well-settled, sturdy, and up to date recurrently.
The authors observe: “With the suitable market indicators, we will de-carbonize aviation and spur a brand new wave of U.S. innovation and clear vitality jobs. Nevertheless, modeling uncertainty as we speak is a multiyear growth downside because of the buildout schedules of SAF manufacturing amenities.” Part 40B of the IRA can’t be carried out or used successfully if bio-innovators don’t urgently obtain readability and certainty on this situation.
The administration ought to instantly acknowledge Argonne GREET and supply the knowledge that may assist long-term planning and funding in a extra sustainable future for aviation.
