I work in a facility that handles methanol. At any given time we have about 8million gallons on hand with a max capacity of just over 12m. Our tanks and pipes are steel, as long as the product is pure, it will not rust steel. Our load out arms are aluminum, no corrosion there either. The only issue with the stuff, you need to use buna n (nitrile) seals, orings, gaskets.
Also, methanol's stoichiometric is around 7:1 (gas is 14.7:1), so you burn twice as much methanol as you do gas.
Being hygroscopic is another concern. Same as ethanol, and there is a reason we don't want to run e10 in our skis.
