Study shows full decarbonization of U.S. aviation sector is within grasp

Nov. 16, 2022
An Arizona State team first identified and assessed where optimal marginal agriculture lands already existed in the U.S. They then assessed whether one could grow the right energy crops on the land without using additional water, reports.

TEMPE, Ariz., - Everyday, 45,000 planes fly across the United States, carrying some 1.7 million passengers. Aviation dominates a frequent traveler's individual contribution to climate change, and yet is one of the most challenging sectors to decarbonize, reports. Continue reading original article.

The Military & Aerospace Electronics take:

16 November 2022 - New research published today in the journal Nature Sustainability shows a pathway toward full decarbonization of U.S. aviation fuel use by substituting conventional jet fuel with sustainably produced biofuels.

The study, led by a team of Arizona State University researchers, found that planting the grass miscanthus on 23.2 million hectares of existing marginal agricultural lands — land that often lies fallow or is poor in soil quality — across the United States would provide enough biomass feedstock to meet the liquid fuel demands of the U.S. aviation sector fully from biofuels, an amount expected to reach 30 billion gallons per year by 2040.

“We demonstrate that it is within reach for the United States to decarbonize the fuel used by commercial aviation, without having to wait for electrification of aircraft propulsion,” said Nazli Uludere Aragon, co-corresponding author on the study and a recent ASU geography PhD graduate.
