The use of so-called alternative jet fuel - produced from plant material - will not lead to any significant reduction in greenhouse gas emissions. This is evidenced by results of a study of the international organization International Council of Clean Transportation (ICCT).
Firstly, ICCT experts say in their report, the combined emissions of agricultural machinery in the production of vegetable raw materials for alternative jet fuel negate the effects of its use. Secondly, because plants specially modified for use in industry, produced from this raw material alternative fuel becomes more "dirty".
And finally, thirdly, the raw material is simply not enough to cover all the needs of jet aircraft, given that the demand for biofuels is high enough and in other transport sectors.
ICCT emphasizes: "Assessment of the dynamics of alternative fuel production in the period up to 2050 years indicates that it would be impossible to completely replace conventional jet fuel and to reduce emissions CO2. Estimated demand for jet fuel will be in the year 2050 24-37 EJ (exajoules). The absolute maximum of biofuels that will be available reactive Civil Aviation, is not more than 4 EJ ".
In addition, alternative fuel production cost is high enough, said resource Clean Technica. And ICCT analysis shows that biofuels based on its delivery to the consumer spending is not competitive in relation to conventional hydrocarbon. After all, the issue of fuel costs for airlines is much more sensitive than, say, the automotive sector.
Thus bet on a full transition to alternative fuels civil aviation is simply meaningless, experts conclude ICCT. More or less promising is only the creation of hybrid aircrafts, or fully electrical motors. But that means the return of mass transit sector in the era of the screw, it is unlikely that someone will suit.
