Airlines Could Be Flying on Biofuel Within 5 Years

Industry Hopes for Significant Market Share For Algae and Jatropha by Mid-Decade

By Dave Levitan

Mar 18, 2010

Just a few years ago, the idea of replacing kerosene-based jet fuel with renewable fuel from plants seemed out of the question. The cost of producing such alternative fuels dwarfed that of traditional jet A-grade fuel, and moving a severely carbon-intensive industry toward cleaner fuels would only happen if the economics worked out.

A 2008 spike in oil prices and a global economic slowdown later, and suddenly bio-jet fuel isn’t just back on the table, it might be in your airplane’s engines in the next four or five years.

“Generally speaking, three years ago I think many people felt that it was something on paper and it was a bit of a pipe dream,” said Steve Lott, the head of corporate communications for the airline industry group International Air Transport Association, or . “The tests we’ve seen in the past two years or so have definitely moved the ball forward and accelerated the process forward toward certification.”

The tests Lott mentioned are a series of flights by various airlines around the world demonstrating the capability of so-called “drop-in” biofuels. These fuels, derived from second-generation biomass sources like algae and the plant, can power a jet engine with no modification to the engine or plane, saving the industry from the economic impossibility of upgrading the worldwide airplane fleet.

Continental Airlines, for example, has already flown a using a 50-50 blend of kerosene and algae-based fuel in one engine of a Boeing 737, and Lott said there was even some indication that of the plane’s two engines the biofuel-powered one performed slightly better than the kerosene engine.

Bullish on Algae

Algae — yes, the green stuff you see on ponds — has emerged as the most promising biomass source that could eventually be scaled up to commercial production levels. It can grow in brackish water and in areas that don’t compete with food crops, and it has among the best energy-per-unit-area of growth of any biomass feedstock.

Although no large-scale production of algae-derived jet fuel has begun, there are indications that this will soon change. The U.S. Defense Advanced Research Project Agency, or , has an algae-to-jet fuel project that will begin testing this year, and it to begin mass production by 2013. The agency hopes to demonstrate that production of algae triglyceride — which can then be converted into jet fuel — can come down in cost toward $1 per gallon, making it commercially viable. Only a few years ago, the cost was upwards of $100 per gallon.

Several companies in the U.S. are also attempting to move this field forward, including and , two California-based companies that shared in $100 million in DOE announced in December for innovators working on renewable jet fuel. Solazyme said it is delivering of algae-derived jet fuel to the U.S. Navy, which plans to test the fuel this year.

Jim Proulx, a spokesperson for Boeing Commercial Airplanes, said his company is involved in several biofuel-related projects as well, although for the moment they are largely aimed at testing the feasibility of new types of fuels than actually pushing for a scale-up of commercial production.

“What we hope to see is something in the area of 10 percent [biofuel] use by 2015,” he said. “It doesn’t sound like much, but it is much. It is a couple billion gallons.”

anybody in the industry had expected, she said, and that interest has not died away now
that the oil price has come down from its record highs of last year.

great post

I never found such a great and amazing content and fabulous solution to my problem.......really giving a different idea in applying ideas in planning a systematic way. thank you !

The replacement of

The replacement of Kerosine-based jet fuel by renewable fuel from plant will drive the economy to a higher position. The conversion of organic waste into jet fuel by the help of a plant will help a lot .The proper cultivation of algae and Jatrofa also will help in jet fuel production.If process of obtaining jet fuel from biomass get succeed then we can get our pristine earth that once had.

Your post will be rather good, and I’m sure some will find it interesting because it’s about a topic that’s as widely discussed as others. Some may even find it useful.Thanks so much for your post.

It would be great if this

It would be great if this actually occured, but are biofuels really a long term vaibale alternative, it's possible they could be, but personally I think it's still up in the air as to whether biofuels are part of the long term solution. But nice article!

Jamie -

Its the economics...

It may be technically feasible to grow algae for use as biofuels - but (imho) there is stil a way to go until economically feasible production at an industrial scale...

Biomass, Wind, Solar,

Biomass, Wind, Solar, Alternative, Conventional: our Nation needs ALL these things more than ever. The United States government needs to put priority in supporting long term development and research of all emerging areas of energy. Domestic energy production is key to the economic fruition of America. Instead of spending our wealth abroad for foreign resources, we have a chance to strengthen America’s energy portfolio with our own.

We can already do it now in full scale why wait

We at Green Power Inc for now over 2 Years built and operate a Full Scale System converting all forms of Waste which have Hydro Carbons in it, so nearly everything you throw away with the exception of Metal, Glass and stones into High Quality Fossil Free Fuels. The Fuel can be straight filed into cars and engines, Airplanes etc. no modifications needed. Now you will ask why is this not all over, because of one Beaurocrat in Spokane Washington Ecology Office as he stops us all the way. Other Countries are contracting with us, but in US we are still not allowed to operate full time. We had to lay people off and are asked to move manufacturing overseas, we don’t want to but the local Government actions may force us to do so, so we would lose here in US cheap local Fuel out of waste and the Jobs as well. It feels very bad as we did not take any Government funding to build our system. Our system is ready at full scale and can be implemented anywhere in the world it can give countries fuel and energy independence out of local resources at a much lower price than regular fuel on the Market.
• We have the solution we believe check us out at or on our website .
We did it without Government help and we have it working to prove our claim, on full scale not just lab scale ideas. Why spend Billions of Government funding to develop something when we already have it.
Your Green Power Inc Team
And Garbage we have all over the world enough to do it!
