Boeing Wins FAA Certification for 747-8 Freighter – Bloomberg   1 comment

Big planes are big business. Innovation and different market needs for paasenger and freight keep this sector of the global economy  bouyant.

“Boeing Co. (BA)’s new 747-8 freighter won certification from the U.S. Federal Aviation Administration to enter commercial service, capping a two-year, $2.04 billion delay for the company’s biggest plane ever.

Luxembourg’s Cargolux Airlines International SA will receive the first of the jumbo jets early next month, Boeing said today in a statement. The European Aviation Safety Agency also gave its approval to the new plane, Boeing said.”

High on Pond Scum: When Will Aviation Biofuels Justify the Hype? | Txchnologist   Leave a comment

A further analysis of the development of  aviation fuel from renweable sources such as algae. Sustainable aviation fuel can be produced ….scability and affordability are part of the limiting factors. Self – sufficientcy also has to be factored in…national secutrity definitely is an influencing factor.

“Despite the obvious appeal of biofuels for energy security and environmental sustainability, analysts, researchers and even some within the industry remain skeptical that large numbers of passengers will be kept aloft by pond scum and scrub plants anytime soon. Scalability an issue The issue isn’t whether biofuels can power jets – that’s largely been proven.The question is whether biofuels can be produced at a large enough scale to offset petroleum use – some 19 million barrels per day, according to RAND.Yields from camelina, jatropha and other seed oils are so low that they could only provide a fraction of a percent of oil’s production, according to Bartis.”

As Jet Fuel Prices Soar, a Green Option Nears the Runway   Leave a comment

Aviation biofuel…avant garde and a positive direction in curbing costs and ensuring sustainability.

 

“But aviation is making an important step in breaking free of its petroleum dependence through biofuel.

The ethanol that is typically used in cars—fuel alcohol refined from grain or sugar cane—would not work in aviation, at least with today’s jet engines, because its energy density (the power it packs per gallon or liter) is too low. But numerous start-up companies around the world have been working with a very different fuel derived from oils that have been extracted from plants, animal fat, or grease. The oils are treated with hydrogen to produce HRJ, synthetic kerosene that is chemically the same as jet fuel. Only carbon dating would reveal that it is not made from fossil fuel.”

KLM, First Commercial Biofuel Flight   Leave a comment

KLM, First Commercial Biofuel Flight

By Glenn Pew, Contributing Editor, Video Editor

“A Boeing 737-800 carrying 171 passengers out of Amsterdam for Paris Wednesday moved KLM to say it was “the first airline in the world” to operate a commercial flight on biokerosene (a used cooking oil, Jet-A mix), with more to come. KLM said that by September, 2011, it will begin 200 more flights, flying the same route, and using the same 50-50 blend of fuel. Details regarding regulatory issues are not yet clear. The biofuel portion of the fuel mixture that KLM used for this latest flight was not derived from the camonila or jatropha plants. (The plants have earned attention for their high oil content and low agricultural impact.) KLM used a cooking-oil-based fuel produced by Dynamic Fuels, a joint venture between Syntroleum and Tyson Foods.”

KLM’s biokerosene was created from non-food grade animal fat supplied as a byproduct of Tyson Food’s meat processing plants. That product was refined into biofuel by dynamic Fuel at that company’s facility in Louisiana. KLM first made a biofuel-powered flight roughly 18 months ago, taking forty VIP’s on a 90-minute flight. That particular trip only fed the biofuel mix to one engine. Virgin Atlantic, Birtish Airways and Continental have all flown commercial airliners fueled, at least in part, with biofuels. European airlines are particularly motivated to find a fossil fuel alternative due to a limit set by the European Union. That limit calls for airlines to cut their carbon emissions by three percent in 2012. The flights show progress for biofuels, but according to KLM managing director Camiel Eurlings, “The costs of biofuels need to come down substantially and permanently.” Said Eurlings, “This can be achieved through innovation, collaboration and the right legislation that stimulates biofuel in the airline industry, but with an eye on honest competition.”

Gulfstream G450 crosses the Atlantic on 50/50 biofuel-jetfuel blend   Leave a comment

The use of biofuel in aerospace is reaching viability. The ideal situation will be when biofuel feedstock does not have to complete with foodstock.

 

Honeywell’s biofuel is derived from camelina, a dedicated energy crop that grows in rotation with wheat, which reduces competition with the food market. According to Honeywell, the biofuel offers up to an 85 percent reduction in net emissions compared to petroleum-based fuels. Additionally, it is manufactured using the same hydro-processing technology already used for the manufacture of today’s transportation fuels, and can be mixed with petroleum-based fuel. Furthermore, tests have shown that it can be used for military or commercial applications without need for aircraft or engine modification.

The initial technology was driven by a 2007 contract from the U.S. Defense Advanced Research Projects Agency (DARPA) to produce renewable military jet fuel. Honeywell has experimented with biofuels made from camelina, jatropha and algae in sixteen biofuel test flights so far, and have produced more than 700,000 U.S. gallons (264,979 liters) of Honeywell Green Jet Fuel to date. The feedstock for the transatlantic flight was grown and harvested by Sustainable Oils, a U.S.-based producer of camelina-based technology.
