Economics of Hydrogen/Methanol Storage
« on: November 06, 2005, 09:01:11 PM »
I made up a little spreadsheet to calculate the optimum mix of battery/hydrogen/methanol storage for various price points and usage scenarios.  

Basically, the idea is that, while hydrogen and methanol come with large losses, it is cheaper to build more windmills to make up for those losses than it is to buy batteries.  Also, since hydrogen and methanol production have high fixed capital costs, cost-effectiveness goes up with capacity.  Methanol, for instance, can be cost-effective as a long term storage medium when also used for transportation.  With cheaper hydrogen storage methods, hydrogen can be as well.

This calculation makes a couple of assumptions for simplicity, like 100% battery efficiency, dual-fuel (hydrogen/methanol) backup generators, readily available water for hydrogen and CO2 for methanol production, and averaged windmill output.  I'm sure you guys can come up with more realistic prices and usage scenarios than I can, so here it is:
