Rising jet fuel prices are putting severe pressure on airline companies creating an incentive for aviation bio-fuel research.
If the aviation sector were a country,it would be the eighth-largest
emitter of greenhouse gases (GHGin the world, at 2% of the humaninduced total. In 2010, carbondioxide (CO2) emissions from international aviation amounted to 448 megatonnes (Mt), with forecasts of increased emissions ranging from 682 Mt to 755 Mt by 2020, and as high as 2 700 Mt by 2050 if no action is taken (ICAO,2016).1
Airlines carried nearly 3.6 billion (bln) passengers in 2015.

Production of renewable aviation fuel range alkanes from algae oil
http://pubs.rsc.org/-/content/articlelanding/2016/ra/c5ra23145k#!divAbstract
Assuming that land transportation heads towards primarily battery powerred vehicles, the challenge is then to use the remaining oil wisely. You cannot beat Jet fuel for (non- nuclear) energy density, safety, ease of management etc. It it becomes economic to use bio-derived jet fuel I will be delighted, but I am not holding my breath.. As for pollution, keeping gas guzzlers out of town and cities, and a coherent freight policy so more goes by rail, and a change in the personal transport market... ie rental/UBer / based reduction in onwership,,, Once a ll that s resoved, then lets look at Air transport..
With the discovery and development of much more efficient algal strains, commercial-scale production of biofuel from algae may finally be a realistic promise.Research reported in this news release was supported by National Science Foundation (NSF) Emerging Frontiers in Research and Innovation (EFRI) Grant #1240478.
