If you've got 100 gals of methanol, get yourself 500 gals of waste egetable oil, a few pounds of lye, and make biodiesel to add to your alternate fuels...
You will end up with a fair bit of glycerine to dispose of (or be creative), but it's a fun job (I only make it in half gal continers, use it as an additive (in engine oil, and fuel of gas/diesel cars)...not that often, only when I get enough dry alcohol.)...there's a couple players who partially esterify the oil, and have a partially thinned ester/glyceriene "fuel", which carries sodium/potassium from the lye...I wouldn't do that without an inline pump, and probably not then.
Or you could get on a biodiesel forum, and swap them the meth for some finished fuel...
