Qatari515, all of what you have said makes excellent sense, the thing that surprises me is that Mr. Al-Baker makes it sound like from a technology and certification point of view this is not going to be a big deal. Maybe he is right, the news just got me by surprise.
The question is whether it will happen on such an ambitious schedule, and what will the logistics be for QR aircraft "downroute" (will they need the same type of Petroleum fuel or can they also use Jet A)?
From an environmental and profit point of view, of course it makes sense. Many countries are looking at alternative energy sources. Just read in my newspaper a few days ago that in my home country our president signed an international agreement to begin mass-producing ethanol. The problem with this is that with sugar cane being redirected to your fuel tanks, rum will be going up in price.
