Bloomberg had United Airline's head of sustainability on this weekend, and she said these renewable fuels are 4X as much as jet-A. Ever the green optimist though...(she didn't get that position for no reason I guess), she was quick to add "but if fuel costs keep rising, these become more and more competitive."
4X the price Stoney. >>>> Not the discovery of a lifetime. But that patent might be worth something down the road.
-- We are down to about 2X the price. But that is irrelevant the airlines have to buy to get near their goals for Carbon & in Europe they will be forced to buy and eventually here as well. This is why so many millions of gallons of green air fuel have been sold already and pledged already for the next 4 years- it's happening.
Also Rolls Royce is testing a hydrogen plane.
And electric for small planes,
All on the come.
