Our editor, Louise Poirier, author of our recent Special Report on Bio-derived Alternative Jet Fuels, opines on what she learned in the course of preparing the report for the GBC membership:
For years now, ethanol and biodiesel have successfully wiggled their way into mainstream fuel mixes around the world - yet no alternative fuels have really had the same kind of success in aviation. Granted, jet fuels are significantly harder to develop alternatives for because of the need for a very low freeze point and very high energy content, but alternative jet fuels are still in research and testing stages.
In my discussions with members of the industry, it seems like things are heading in the right direction though. I’ve heard that the only alternative jet fuel that is viable on any kind of scale is Sasol’s synthetic coal-to-liquids jet fuel that is currently available in South Africa. We’ve also got UOP and the University of North Dakota amongst the wide range of folks researching and developing renewable biojet fuel, and ASTM is even in the process of creating a whole new specification just for synthetic and biojet alternatives. These are all great signs for the aviation industry.
But it still seems like these fuels are not really getting the attention they need when it comes to getting policymakers and other stakeholders to take serious interest. Sure, you’ve got organizations like CAAFI, ATA and IATA paving the way with some of those folks, but the fact remains that nowhere in government policy today is there any kind of requirement specifically for alternative jet. And this is a shame. Alternative jet offers the same kind benefits that other alternative fuels aim to provide for other modes of transportation. Joe Kocal, head of renewable jet fuel program from the research and development [R&D] department at UOP pointed out that “One is just to increase the volume of fuel available to keep prices steady; and second, just getting away from petroleum dependence; and lastly, the energy security issue.”
An article from USA Today back in January stated that “The U.S. government, environmentalists and even the big oil companies are working together to develop alternative fuels from these and other sources. Their goal: to replace a significant portion of the 19 billion gal of kerosene that U.S. carriers burn in their planes each year and to do it by the end of the next decade. If they succeed, airlines will reduce their carbon footprint - and save big money that could possibly help hold down fares.”
So although we’re hearing great things about alternative jet, it still seems to me like it’s the next ‘always five years away’ kind of thing, sort of like hydrogen. If the certification process manages to go through without a snag over at ASTM, alternative jet would definitely be ready for fleet usage as soon as the end of this year. But where are these fuels going to be made? Who will make them? And where are the feedstocks and resources and policy measures that will help get these fuels made on a commercial scale? They’re definitely not around right now. And besides that, the aviation industry uses a staggering amount of fuel every year - in 2007, 5.1 million barrels of jet fuel were used per day, according to ATA’s Web site - so it’s going to take a lot of alternatives to make a dent on those kinds of numbers. This kind of transition would require a tremendous movement by industry and government around the world to truly take off.
Yes, I absolutely agree that it’s possible that alternative jet fuels will be viable in the next five years or so, but I don’t think that we’ll really be coasting around the world in planes fueled entirely by things like algae and chicken fat for a while beyond that. Even with all the fantastic research, brilliant processes and passionate advocators out there on alternative jet’s side, we just don’t have the means to do it yet - but we need to get there and it looks like we definitely will (given some more time, of course).
