The idea of seperating the CO2 from the air and making Methanol had been dubed the SeaLand process by another group.

A fine idea.   IF you have excess electromotive force with nothing to do.

That is a big IF.

I spent a day looking into a basic set of Eq. to do the sealand process.   I was looking at over $250,000 to set up with wind generators, no land costs, and a spitballing of the reaction/process cost to make Methonal.  100 Liters a day production.

You might be able to count on selling Nitrogen Gas/Liquid Nitrogen, until there is mass Methonal production (oversupply of N2) or a reduced industrial need for Nitrogen (via recession) You might be able to turn an additional buck splitting water, taking the H2 and combining with your excessive N2.   But that model needs cheap, excessive energy.

Can you give any more details of the reactions proposed?
For those thinking about simply pumping CO2 into the ground, here is a little side reaction you need to think about:
