FF for carbon sequestration

[rashidas]

Can a focus fusion reactor be designed to fix carbon dioxide from the atmosphere? If such a system could be developed it could reduce global warming and produce marketable products like carbon neutral hydrocarbons. This could provide an alternative way to store energy from fusion reactions.

It could provide electricity and process heat for such a reaction but someone would still have to develop a cost-effective method of atmospheric CO2 sequestration in the gigatons-per-year range … and [em]that’s[/em] the sticking point.

Barring such a breakthrough it would be much simpler and much, much cheaper to just use Focus Fusion units to replace fossil-fuel power plants while humans begin working to reverse deforestation and begin planting trees.

And the increase in the availability of easily distributed carbon-free power enabled by FF units will greatly aid humanity in coping with the Century of Storms.

to use fairly round numbers,
4.4 Gt / yr = 10^14 mol CO2. at -427.4 kJ/mol std enthalpy change of formation, it would cost 4 x 10^8 TJ per year, or 2.7 million of the 5 MW reactors.
kind of a lot

Does sequestration have an inherent problem? When you put all that CO2 some place, it would seem sooner or later it would need to come out. Just like a melt-down or an accidental release of radioactive clouds. If sequestration is a choice, then wouldn’t processing into separate elements be a step to a solution? Just a weird thought.

There is this LLNL research going on that if proven feasible and desirable, Focus Fusion could possibly tie into…

i think my calculation, above, showed that it is impractical to use focus fusion for processing that much CO2 into separate elements

Trees.

Solar-powered and they turn the CO2 into a usable resource that is self-storing until needed.
