Mr. Eddie Wilson:

It is all about whether energy companies will be incentivised to produce that. It is three times more expensive than standard Jet A-1 aviation fuel. There is no joined-up thinking on this in Europe. Individual governments are mandating that airlines take so much, but nobody has put any thought into who will produce it.

One of the biggest plants producing at the moment is in southern Spain by one of the oil companies there. What they would produce in a year, however, we would use in one month. We need that type of volume.
