IMO biodiesel, ethanol made from sugar cane, and possibly even synthetic fuel1 make more sense than corn-based ethanol for energy dense storage.
(1 use excess cheap electricity for electrolysis of water into H2, combine that with sequestered CO2 to make methane, then use the Fischer-Tropsch process to turn that into liquid hydrocarbon fuel)
