Airlines for America (A4A) has applauded the approval and publication of a new sustainable aviation fuel (SAF) specification to enable environmentally friendly jet fuels for use by US airlines, the company said.
The specification was approved and published by ASTM International, a standards-development organizations, with support from the Commercial Aviation Alternative Fuels Initiative® (CAAFI), which A4A co-founded in 2006.
The new annex to the SAF specification, D7566, establishes criteria for the production and use of what is referred to as catalytic hydrothermolysis jet fuel (CHJ), a type of synthetic kerosene. The standard provides that CHJ fuel, which was developed by Applied Research Associates (ARA), may be blended at up to 50 percent by volume with conventional jet fuel. It represents the sixth approved pathway for the production of SAF.
A4A is an industry trade organization for the leading US airlines. A4A works collaboratively with the airlines, labor, Congress, the Administration and other groups to improve aviation for the traveling and shipping public.
