Biomass/CO2
Posted: Sun Mar 29, 2020 10:11 pm
What's the most reasonable way to generate these after most of the biomass recipes got moved to the composter?
Previously most of my CO2 came from biomass, either via phytoplankton or wood. Neither of those is particularly workable now. Aiming at a rather conservative 4 HPFs (18k CO2/m), which would feed about 1/3 of the CO2 I really need, is about 600 biomass/m.
Various options I have looked at:
Guar bean seeds: 6 solid separators, 13 1/3 plantations. Reasonable, except it eats 18k CO2/m. Nice that it would be a relatively closed loop, not so nice in that guar is not particularly useful if you aren't drilling.
Wood: 100 composters, eating 40 MW, and eating 3000 wood/m. All of the fast wood options use a lot more CO2 than this would generate, also, it seems a bit absurd for it to take 40MW to make wood into something burnable into CO2.
Logs: only 25 composters, but the non-CO2 recipes would need 187 fastwood forestry to produce it, and the CO2 recipes would all eat as much or more than the biomass would produce
Phytoplankton: 20 composters, but needs 30 phyto farms, and eats more than a yellow belt of iron ore. Flue gas recipe only needs 15, may be vaguely reasonable.
Sorting from soil: no composters, about 12 MW of power running 20 separators and ~23 soil extractors. Generates a pile of excess sand, coarse fraction, and limestone, but those are workable.
I suspect I will end up moving back to using coke->CO2 as the primary source, with the soil approach backing it up. Not the nicest or most compact thing, but it seems reliable.
