Porsche and international partners working with the Chilean operating company Highly Innovative Fuels (HIF) have started the industrial production of synthetic fuels.

Wow, they really dont talk about the fuel do they. What system have they found to convert atmospheric carbon into a liquid form with just electricity? Im more interested in the sequestering potential than immediately returning it to the atmosphere.
The tech has been known for decades. It just needs clean hydrogen. You can either go the hydrogen fuel cell route, or combine it with CO2 to make liquid fuel, but the source of hydrogen is the crux of the problem.
Im bigger on the fan producing enough fuel for the mining and construction of it and the facility and maintenance and upkeep. This has been a re-occuring point of can we create wind and solar panels just from wind and solar panels without digging up oil. As for sequestration. What is the point if we are still digging up oil and refining it into the same fuel??? I could see it being something if we were otherwise not digging up hydrocarbons but I fail to see how sequestration is better than replacement while we are doing that.
I dont know what your first two sentences are about. As for sequestration, just imagine it as an independent effort to reduce greenhouse gases already in the atmosphere.
yes but what I mean is if we are putting in co2 from fuels then usually it will reduce more to just use the fuel and not pull out additional oil over sequestration. simply due to overhead. the fuel from oil produces co2 and the refining produces co2 and the extraction produces co2.
I dont know what you mean by pulling out additional oil over sequestration. sequestering is just taking carbon out of the atmosphere, to be kept away from the atmosphere in some kind of solid form. Plants are the easiest example.
yes. yes. I understand that. but fuel is a fungible commodity and if fuel is created in this process (it is) utilizing it will keep more carbon out of the atmosphere if we are still getting it from oil. If we have completely stopped using oil for fuel then yeah sequestration makes sense, but if its making fuel and we are using fuel (from dug up fossil fuels) the sequestration will result in more overall co2 than using it.
There is biochar which can be scaled by providing cheap pyrolysis retorts and training how to bioactivate it. Incentive is increased agriculture productivity long-term. Capture should be done directly from flue gas since not needing enrichment. There are also carbon-negative concretes which have good potential for capture.
Synfuels from 100% renewable are at least carbon neutral, which is as good as it gets.
that's not taking carbon from the atmosphere, that's just carbon left behind from burning organic materials. That's emitting CO2.
