I'm curious if Prometheus has considered any options for permanent sequestration. Perhaps buying an old oil rig and pumping electro fuel back into it.

It's obviously hard to find an economic incentive to do this, but maybe carbon credits would make it possible.

How would that be better for the environment though?

Unless we have a way to electrify all planes (we don't currently), this is the next best thing. I think the key is to ensure biofuel never gets cheaper than regular fuel, to avoid incentivizing flying more.

If you sequester what you pull out in some old oil well, while American Airlines is pumping out from the next oil well, it has to be less effective (and thus release more CO2 in the process), than just you sending your oil from captured carbon directly to them.

It would make sense in that we need a net reduction in atmospheric carbon, and not 100% of carbon emissions come from burning fuel.

Though, I do see your point-- This only pencils out once you've captured 100% of the available fuels market, which is quite large.
