Airlines could soon be using biofuels in their commercial jets
Final specification for biofuel could be here this summer

When most people think of alternative fuels, they often look towards the automotive industry. Modern cars and trucks are already available that can be powered by hydrogen, batteries, and other fuel sources such as biofuel derived from corn and other materials. The aviation industry is also looking to “green” biofuels to power commercial flights.

The Air Transport Association (ATA) has announced that the ASTM International Committee on Petroleum Products and Lubricants has given the green light for a new jet fuel specification to push aviation biofuels. ATA President and CEO Nicholas Calio remarks, "The committee endorsement of this specification is significant for all consumers of jet fuel, bringing the airline industry one step closer to widespread production of cleaner, alternative fuels that will help meet our environmental goals while enhancing the security and competitiveness of our energy supply."

The FAA is also pleased that the new biofuel specification has been approved. FAA administrator Randy Babbitt said, "This is a significant step toward a new era of greener and more energy-independent air travel. We anticipate publication of a standard in the next few weeks will open the door for production of commercial aviation biofuels that can be used without changing aircraft systems or airport fueling infrastructure." 

The new biofuel specification will allow for blends of up to a 50 percent mixture of traditional jet fuel and 50 percent of the new biofuel produced by feedstocks like camelina, jatropha, or algae. The ATA said in a statement, "[The ATA has] voted to approve the addition of a new bio-derived jet fuel annex to the alternative jet fuel specification D7566. This effectively concludes the technical review process, allowing for final issuance of the revised specification by August of this year."

NASA has been researching biofuels that are made from a type of rendered animal fat.

The USAF has also been working to certify biofuels for military aircraft as well. The USAF Globemaster III is the first military aircraft certified for biofuel use. The Air Force noted that its 50 percent mixture of JP-8 and 50 percent HRJ biofuel had no discernible effects on engine performance.

Full speed ahead on the road to hydrogen powered commercial flight... :-)

hopefully your joking..

else given a standard 747, once the space needed for the hydrogen fuel is taken into account, there will be space out on the wing for you

LOL

I'm totally serious! :P

why so serial?

Totally serious.

There are more ways of storing H2 than having it in as a cryogenic liquid a bog-standard high pressure tank.

hydrocarbons are still one of the best fuels w.r.t. energy density (energy/weight)


No corn no corn no corn no corn....

Please, sweet merciful God. Make sure they don't use any corn. It's less efficient and gives worse emissions.

Plus then cereal will be more expensive because demand will grow

"I'm super-cereal." Sorry had to do that little man-bear-pig reference.

Uh was that sarcasm about cereal? Not sure...

In any case, ethanol isn't as viable as jet fuel. I think they closer to using butanol.

I didn't see any mention of ethanol/corn in the article. . . this is biodiesel from algae and certain plants (Jathropa and Camelina). I'm not familiar with either of these plants but as long as it's not ethanol which really doesn't have the energy density to be economical (among other issues) for airplanes, I'm all for it.

Maybe the airlines can use used cooking oil.

“green” biofuels

Why not just use that old organic rag paper we call money. It's green and plentiful these days with the presses running full bore.
