8. One clear advantage of ethanol over hydrogen is that it is a liquid.

Ethanol is easy to contain. Hydrogen is not as easily contained (because it is the smallest molecule, it tends to sneak out of things.) Ethanol is a physically larger molecule. You can easily pump it from one tank to another just as we do gasoline.

Producing ethanol will likely involve first “splitting water" producing hydrogen and oxygen (just as green plants do.) Then, it will be combined with carbon (just as green plants do.) Just think of it as hydrogen in a more convenient form.
