Del, there is much less chemical energy (and chemical energy, technically the specific heat of combustion, places the high boundary on theoretical fuel cell energy yield) in one molecule of methanol than in 2 1/2 dihydrogen molecules. So I suspect that Manhattan Scientifics is engaging in a bit of storytelling. As for the hydride system - do they say how much pressure is required for that storage density, and how much of that 40% more hydrogen can be tapped without improprieties like heating the adsorbent? For cars, low pressure and easy fuel release will both be - if not absolute requirements - strong selling points. What percentage of the weight of the hydride unit is available hydrogen?
