True, but, this method also gives of CO2 as well as the H2. These two together, are precursors for Methanol which is a basic feedstock for many of the common chemicals made / used today, in the petrochemical industry. With the right catalyst, H2 and CO2 can be made into a multitude of different products ( including gasoline ). I know, I said the bad " G " word, but, let's face it, this world is not going to get of it's habit over night.
One thing about this method, is that by altering the metal catalyst a bit, you produce CH4 -- methane, which is another petrochemical feedstock, as well as the H2 and CO2. I think that in the future, that if any petrochemical wants to truly be green, this might be one of the way they will do it, for their raw feedstock. Ethanol has a few things that detract from it as a feedstock, namely a higher carbon to hydrogen ratio, not much, but, enough to cause an increase in cost, of manufacture, because of the need to do something with it, be it getting rid of it or collecting it for other purposes. Another problem with ethanol, is it's affinity for water, the added cost of denaturing, and the denaturing materials themselves, all of which may be unsuitable for feedstock purposes. On the other hand, the CO2 and H2 or the CO2, H2, and CH4 ( depending on the catalyst and what the final product is to be ) would be a good starting feedstock.
