"The reason, Deluga said, is because all water must be removed from ethanol before it can be put into a gas tank. But he said the new process, which strips hydrogen from both ethanol and water, doesn’t require such a pure form of ethanol."

This is a huge point. Anhydrous or 100% ethanol is expensive to produce because it takes alot of heat to get out that last 5% of water. 90-95% ethanol is radically cheaper to produce, far cheaper than gasoline. Add to that the higher conversion ratio, and you should have a winner, if this technology can be proven on a practical scale.

Isn't this discussion originally about getting Hydrogen? Who cares about the Ethanol, why not just use water?
