Sustainable Aviation Fuels: The challenge of decarbonization
Open accessAbstract
Aviation is steadily growing worldwide as well as in the European Union (EU). Overall, EU transports increased their GreenHouse Gas (GHG) Emissions since 1990, while the other energy sectors succeeded in achieving a constant reduction over the same period. In this context, air transport is the most critical area to decarbonize, given the limited number of options that can be implemented, such as optimization of flight routes, increase of jet engine energy efficiency, and few others. Switching to renewable or low carbon fuels is thus the main opportunity for aviation. Large scale deployment of Sustainable Aviation Fuels (SAF) is however a real challenge, as it requires large investments in new production facilities, strong reduction in production costs (over the entire value chain, i.e. including feedstock production, collection and delivery), and considerable investments in ASTM certification. The present work shortly reviews the perspectives of aviation fuel in terms of demand and GHG emission trends, possible routes to jet fuel production, and the status of ASTM certified routes to jet fuel as of today.

The demand for conventional aviation fuels will continue to grow to 860 Mt/year by 2050, which is more than 4 times the demand observed in 2010.
“It is currently estimated that the demand for conventional aviation fuels (CAF), such as Jet A and Jet A-1 (comprise of 20% naphthalene, 20% paraffins, 40% iso-paraffins and 20% aromatic compounds from the crude distillate), will continue to grow to 860 Mt/year by 2050, which is more than 4 times the demand observed in 2010 [115].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
