A normal Boeing 787 passenger plane 
will next year jet from London to New York
 in a bid to prove long haul flights 
can be fuelled using only
 sustainable aviation fuel (SAF).
[How is sustainable aviation fuel SAF made?
SAF is made from hydrocarbon molecules
 through a process called hydrodeoxygenation.
 Oxygen originating from renewable
 raw materials is removed with the 
help of additional hydrogen. 
Other impurities, like sulphur and nitrogen, 
are also removed during this process.]

[Guilt free flying is one step closer to reality,
 the government has said,
 as it awarded Virgin Atlantic up to £1m
 to test the first transatlantic commercial flight
 powered by green fuel.]
