I imagine so. The main trouble with the biofuels is that you'd have to get everything else right for it to truly be neutral impact. (i.e. not depleting the soil, making the chemical fertilizer, reactions to convert biomass into ethanol, etc.) Electrolyzing water with wind/solar/nuclear would seem to result in far fewer steps that could go wrong.
