Carburant alternatif au sol

A l'aéroport de L.A. ( LAX ) huit compagnies ont signé un accord avec Rentech ( pétrole ) et Aircraft Services Itl Group
pour l'utilisation de carburants issus de la biomasse dans les véhicules de "ramp"

Eight airline members of the Air Transport Association (ATA) have signed a first-of-its-kind deal to purchase renewable fuel made out of urban green waste for use in ground service equipment.

The eight airlines have signed an agreement with Rentech Inc and Aircraft Services International Group (ASIG) to purchase up to 1.5 million gallons per year of renewable synthetic diesel fuel (RenDiesel) for use in ground service equipment at Los Angeles International Airport.
The agreement will take effect in late 2012 when Rentech’s fuel-producing plant is scheduled to start operations.

The eight airlines are: Alaska Airlines, American Airlines, Continental Airlines, Delta Air Lines, Southwest Airlines, United Airlines, UPS Airlines and US Airways.

Bonjour, chers tous.

LH vient de commencer un service quotidien en faisant voler un A321 ("Legacy", ... bien évidemment) au bio-fuel !

Lufthansa commences daily biofuel flights with A321

[Vous devez être inscrit et connecté pour voir ce lien] has launched the world's first regular scheduled commercial flights powered by biofuel.
For six months, a Lufthansa [Vous devez être inscrit et connecté pour voir ce lien] A321 will fly four rotations a day on its normal Frankfurt-Hamburg scheduled service with 25% of the aircraft's power provided by biofuel.

LH ! Encore une 'première' pour Lufthansa !

Lufthansa says it intends this to be a carefully controlled trial for its biofuel operations as well as a commercial venture.
The aircraft flying the route for the trial period is airframe D-AIDG, a recently-delivered A321 powered by new International Aero Engines V2500s.

Voilà le choix de moteurs ! Il convient de réfléchir !

For all these flights its right engine will be fed a 50:50 mix of ordinary kerosene and synthetic fuel derived from sustainably produced biomass, and the left engine will be powered by normal jet fuel.
The purpose will be to monitor the relative engine performance, fuel consumption throughout the trial, and to be able to observe whether, after six months, there is any difference in the condition of the two engines.
Airbus and IAE are partnering Lufthansa in this venture, as is Finnish fuel manufacturer Neste Oil. The fuel itself was certificated for commercial use on 1 July, and has been approved both by the European Aviation Safety Agency and the US FAA.

Excellent !

The biofuel is based on jatropha, camelina and animal fat. Airbus explains that it is a biomass-to-liquid blend of hydro-processed esters and fatty acids, and Lufthansa says the source is a combination of "plant oils and animal waste" the origins and production of which have also been researched for sustainability.
At present the maximum permitted biofuel mix for commercial flights is 50%, and that is what Lufthansa is using for the trials.

De la discipline, donc ! Normal !

The airline says that the present price of the biofuel is twice that of ordinary aviation kerosene, but it is necessary for aviation to start down the sustainable fuels route for climate change reasons, but also because mineral oil is a finite resource that will become more expensive while biofuel will become relatively less costly.

Voilà un bon point ! Point essentiel !

The carrier estimates the cost of the trial will be €6.6 million ($9.3 million), of which €2.5 million is being supplied by the German ministry of economics as part of a programme known as FAIR (future aircraft research), which is examining biofuel compatibility and the uses of liquefied natural gas in aviation among other projects.
Lufthansa's first flight departed as LH013. Using biofuel for the trial period will cut carbon dioxide emissions by up to 1,500t, the airline claims.

Dossier très intéressant ! A suivre !
