The article has a numbers problem. It's "$39" to capture a ton of CO2 in the solvent but they don't explain how they extract it. They describe converting it to methanol, but if you're creating an equivalent ton of methanol then that's worth about $7,500 given that 2 lbs (1 gallon) of methanol costs about $15. They also need to get a bunch of hydrogen atoms from somewhere for that conversion (CH3OH) which is not explained.

So we gotta ignore the methanol thing and assume they're just extracting pure CO2 from the solvent. But how? If they're pulling it out as a gas then they'd be better off just using a vacuum to suck on the power plant's exhaust. And if the CO2 is somehow being extracted as a liquid then that's an incredibly exothermic reaction and the article is really burying the lede. Either way, all we have left is a bunch of CO2 with no explanation as to what we're supposed to do with it.
