A Menu of Sustainable Feedstocks for Producing SAF
An estimated 1 billion dry tons of biomass can be collected sustainably each year in the United States, enough to produce 50–60 billion gallons of low-carbon biofuels. These resources include:
Corn grain
Oil seeds
Algae
Other fats, oils, and greases
Agricultural residues
Forestry residues
Wood mill waste
Municipal solid waste streams
Wet wastes (manures, wastewater treatment sludge)
Dedicated energy crops.
This vast resource contains enough feedstock to meet the projected fuel demand of the U.S. aviation industry, additional volumes of drop-in low carbon fuels for use in other modes of transportation, and produce high-value bioproducts and renewable chemicals.
unicorn farts not on the list thought
This greenie Jet fuel currently costs 6X what petroleum based jet fuel costs.
Hey, if you are going to lose money, go big!
Well then, maybe it IS true, that the unicorns never got on the Ark. 🤗
I call BS on this technological black hole that endlessly sucks down wasted $$$.
Pick your favorite failure mode…. Capital cost way more than the amount plucked out the air by promoters, online availability much lower than claimed, way excessive maintenance costs, feedstock availability over estimated, etc.
Jimmy Carter style deja vu all over again. A game is being played out.
The supersonic aircraft itself may be an amazingly successful technology - I have no idea, outside my expertise. The trendy hook of sustainable energy is a toss out to secure funding. Reel in a big $$$ sucker.
So no Skittle’s poop as a exhaust product? The millennial crowd will be crushed.
One flight of 5K miles, and how many miles in a car would that fuel? It doesn’t matter if it is magic fuel, it will take a LOT of it.
