I see H2, DC power, and CO2 DAC, costs but no total.

I'm quite curious what their cost is today.
You could produce about 8KG of CH4 with 2KG of H2 and 6KG of C or 22KG of CO2.
At $250/MT would work out to about $5.50 and the 2kg of H2 would be $5 assuming $2.50/kg so lets say $10 for simplicity.
1kg of CH4 at STP is 1,396L (according to GPT since I'm lazy right now) which is about 50cf.
That's not even close to $10kcf (assuming that this means killo-cubic-feet which as a Canadian makes me cringe).
A tonne of CO2 is 12/44 C, or 273kg. So let's call it $1/kg because 250 ~= 273.
A kg of CH4 is 12/16 C and 4/16 H, so a kg is $0.75 for C + $2.50/4 for H = ~$1.40/kg.
https://www.epa.gov/cmop/updated-coal-mine-methane-units-con... says 1000 cubic feet of methane is 19.26 kg. Call it 20 because we're doing it in our head.
$1.40 * 20 = $28 / kcf.
So it was 400cf or 0.4kcf for $10, so yeah you are right. That's actually not terribly far off their white paper actually. It's not as good as current market prices $12/kcf but it is not so far off, particularly if you consider potential subsidies for capturing carbon.
Thanks for that.
Both processes are directly proportional to the cost of electricity and heat so assuming the thesis of decreasing solar costs holds true, it's a question of when not if.
