So Virgin has tested biofuel on a B744, 20% on one engine, made of coconut oil and palmoil. If you use 20% on all engines it´s 48 thousand liters, which is a fair bit.

I don't understand why Greenpeace aren't happy with this move by Brason.
Are they not happy with anything!?
Greenpeace get on my nerves! They should be tougher punishments for breaching security like that at Heathrow  Angry

Sure they love to hate aviation, the root to all evil in their world.
This could be good for farmers in 3rd world, whom make better living by increased price in coconut oil.

So Branson has run turbine engine with something other than pure Jet-A. It hasn't solved anything. The engine manufactures have know for decades that they can run on alternate fuels. I recall the Garrett 331 MM had a chart showing the spec gravity settings for other fuels. I'm pretty sure the Army has the same for their turbine powered tanks.

The real issue is not can it run on coconut oil or grain alcohol, but can those fuels give the range for volume that is acceptable and the cost factor. Also distribution in aviation is a big problem. All airlines at most airports share common fuel. They would all have to certified and willing to use a blend.

Branson's fuel is at least 10 years away from use om passenger aircraft.

What is happening is JetA1 made from Coal and Gas.
SASOL in South Africa is near approval for 100pc JetA1 made from Coal.
Shell in Doha are a year away from JetA1 made from gas. (Qatar has unlimited supplies of gas)

Well, this is something that should´ve started long ago, I think Russian aircraft got a good market in Cuba, Vietnam
and India, all three big coconut producers, countries that have operated many Russian aircraft in the past.

That's exactly my concern. I really don't want to see the price of food products going threw the roof because its also a fuel source. Not to mention, I seriously doubt we can produce enough biofuel to sustain airline operations around the globe.

I forsee a return to airships and sailboats in the next couple of centuries.  frown

This is promising. Its my understanding that the US has coal deposits that made Saudi Arabia's oil reserves look small.

OK perhaps not the right word, but more than they know what to do with. It comes out the ground for free when they look for oil so using it through a Fisher Tropic process to make aircraft fuel is a good idea.

Fischer-Tropf fuels (what SASOL is using) are a great alternative for dwindling hydrocarbons, but their carbon footprint is enormous (much bigger than the equivalent hydrocarbons) so they don't fix any of the environmental issues. They actually make them worse.

Because "Biofuel" poses a threat to the rainforest and because concerns mount over fuel-versus-food competition?

As said before, Bio-fuels diversify the use of natural substances away from more local and more conventional uses such as food. In the VS tests, the biofuel came from a particular plant in South America; this is significant because again, as said by NoUFO, this will mean that rainforest is likely to be replaced with land used to produce these fuels. Trees act as Carbon syncs, and if you take these away, then you really defeat the object.

However, although I do not want to see bio-fuels become more frequently used in commercial aviation, at least VS are trying something out, a slight step in the right direction.

Well, I think farmers in the 3rd world should get a better price for their produce. With biofuel "refuelstops" I think
also infrastructure in some of the 3rd world countries could benefit.
