Carbon sequestration and biofuels that are actually carbon neutral may be similarly implausible.

Carbon sequestration and biofuels that are actually carbon neutral may be similarly implausible.
- guntars 7y agoWhat’s the reasoning behind your statement? I think both are already being done, the economics are just not there yet. Digging up free energy from the ground is just too cheap.
- gameswithgo 7y agoThe scale of co2 that would need to be sequestered is massive, I don't think anyone has a vaguely viable plan of how that would be done. Most attempts at biofuel are not even net positive on energy. if we did get there then the question is how much forest do we have to clear to grow biofuel AND eat, and what net effect does that have on co2. Hard problems all around.

- ars 7y agoIt's not necessary to do that. We could reserve use of hydrocarbon fuel to airplanes, and it would be fine. It's not necessary to go to zero.

These processes have fairly terrible efficiency of course, compared to batteries, but are useful for applications where you absolutely need high energy density fuels.
