And to make things even more complicated there are plans in the works to use bio fuel jet fuel which naturally carries more water for various reasons.firstly: no, that is NOT the very definition of Geoengineering - additives in Jet fuel are just part of the jet fuel!
Secondly - patents for additives are pretty much irrelevant. The makeup of Jet A1 is set by Def Std 91-91, which is currently at Rev 7 - only the additives allowed in that are permitted in Jet A1 - adding anything else without approval is actually a crime in at least most civil societies.
I am surprised that no one has gone off the deep end about JP-7 which was used for very specific aircraft and pretty much all of them in a spy/secret category.
The fuel alone had some additives but they also needed to carry ignition inducer for use of afterburners because the JP-7 would not ignite in the afterburner stream without help.
