If you've got a clean, cool supply of CO2, say from an ethanol facility, it is pretty easy to synthesize MeOH (or more EtOH) if you've got hydrogen available. Room temperature one atmosphere CO2 is easily captured and stored, while the harder to handle hydrogen can be generated from wind when conditions are right. Given a little capital investment you can manage $2/gallon MeOH and the market is $4/gallon right now.

If you grind and boil the corn feedstock for the ethanol plant in the ethanol itself you can extract about six gallons of oil for every hundred gallons of ethanol produced. Biodiesel is about 10% methanol by volume. Corn production diesel numbers are all over the board but it would appear that this amount is sufficient to handle all phases of crop production.

Now if only there were a way to make ammonia using wind power :-) We got some interest in this when prices were $700/ton ... and what I heard late last week is that it's now $1,200/ton, and I find myself called away to another meeting that might lead to development funds. I'm glad things are so serious that folks are starting to take the renewable options seriously ... I just worry we're over that stinky ol' remediation event horizon, where we don't have the energy to build the replacements.
