IATA: SAF production doubled in 2023, expected to triple in 2024

The International Air Transport Association announced Dec. 6 estimates for sustainable aviation fuel (SAF) production.

In 2023, SAF volumes reached over 600 million liters (158.5 million gallons), double the 300 million liters (79.25 million gallons) produced in 2022.

SAF accounted for 3 percent of all renewable fuels produced, with 97 percent of renewable fuel production going to other sectors.

In 2024, SAF production is expected to triple to 1.875 billion liters (495.3 million gallons), accounting for 0.53 percent of aviation’s fuel need, and 6 percent of renewable fuel capacity.

The small percentage of SAF output as a proportion of overall renewable fuel is primarily due to the new capacity coming online in 2023 being allocated to other renewable fuels.

“The doubling of SAF production in 2023 was encouraging as is the expected tripling of production expected in 2024,” said Willie Walsh, director general of IATA. “But even with that impressive growth, SAF as a portion of all renewable fuel production will only grow from 3 percent this year to 6 percent in 2024. This allocation limits SAF supply and keeps prices high. Aviation needs between 25 percent and 30 percent of renewable fuel production capacity for SAF. At those levels aviation will be on the trajectory needed to reach net-zero carbon emissions by 2050. Until such levels are reached, we will continue missing huge opportunities to advance aviation’s decarbonization. It is government policy that will make the difference. Governments must prioritize policies to incentivize the scaling up of SAF production and to diversify feedstocks with those available locally.”

CAAF/3 outcome

The third Conference on Aviation Alternative Fuels (CAAF/3) hosted by the International Civil Aviation Organization agreed a global framework to promote SAF production in all geographies for fuels used in international aviation to be 5 percent less carbon intensive by 2030.

To reach this level, about 17.5 billion liters (4.62 billion gallons) of SAF need to be produced.

“Governments want aviation to be net zero by 2050,” Walsh said. “Having set an interim target in the CAAF process they now need to deliver policy measures that can achieve the needed exponential increase in SAF production.”

Demand is not the issue: Every drop of SAF produced has been bought and used.

In fact, SAF added $756 million to a record-high fuel bill in 2023.

At least 43 airlines have already committed to use some 16.25 billion liters (4.29 billion gallons) of SAF in 2030, with more agreements being announced regularly.

Unlocking supply to meet demand is the challenge that needs to be solved.

Projections are for over 78 billion liters (20.6 billion gallons) of renewable fuels to be produced in 2029.

“Governments must set a policy framework that incentivizes renewable fuel producers to allocate 25 percent to 30 percent of their output to SAF to meet the CAAF/3 ambition, existing regional and national policies as well as airline commitments,” IATA stated.

Policy objectives

According to IATA, effective production incentives for SAF should support the following objectives:

• Accelerating investments in SAF by traditional oil companies

• Ensuring renewable fuel production incentives encourage sufficient SAF quantities

• Focusing stakeholders on regional diversification of feedstock and SAF production

• Identifying and prioritizing high-potential production projects for investment support

• Delivering a global SAF Accounting Framework

Unlocking diversification

Approximately 85 percent of SAF facilities coming online over the next five years will use hydrotreatment production technology, which relies on inedible animal fats (tallow), used cooking oil and industrial grease as feedstock.

According to IATA, limited quantities of these necessitate policies to:

• Diversify SAF manufacturing by increasing production through pathways already certified, in particular the alcohol-to-jet (ATJ) and Fischer-Tropsch, which use bio/agricultural wastes and residue

• Promote investments in, and the fast-tracking of certification for, new SAF production pathways currently in the developmental phase

• Identify more potential feedstocks to leverage all SAF technologies to provide diversification and regional options, including those with side benefits such as environmental restoration

Passenger support

A recent IATA survey revealed significant public support for SAF.

Some 86 percent of travelers agreed that governments should provide production incentives for airlines to be able to access SAF.

In addition, 86 percent agreed that it should be a priority for oil companies to supply SAF to airlines.
