First of all it is NOT the same thing as in a refinery. At all.
And secondly, there is NO LOGIC to the govt trying to mandate all of this 'green' cr*p so I hope we all don't try to make sense out of any of it. And the answer is still yes - you can make jet from renewable sources same as biodiesel. Animal fat, cooking grease, etc. You just have to have reactors capable of making the kerosene range hydrocarbons. Or as in this article, you use ethanol or biomass (

https://www.energy.gov/eere/articles/renewable-jet-fuel-taking-flightThere are multiple pathways. It is called "renewable" because they are NOT USING OIL. Ethanol from corn or biomass from dead trees/bushes in the forests are considered 'renewable'. Now to make the fuel consumes energy, yes, but stupid Liberals don't know a thing about that. Some reason they think a Tesla is EMISSION FREE. Or there lights turn on at their home, because of MAGIC. They are clueless where ENERGY comes from and trying to argue with them is like talking to a stump.
But I digress. What stocks should be we play if we are forced into more renewable fuels.
