First off this seems like a really important addition to solar in general. My impression is that hydrogen is easy to make, can be a closed water cycle (uses the same water it generates to when release the energy), and the only downside is the inefficacies of compressing it to store it among the other steps.
Does anyone know if this would be a practical source of heat say at night, considering what I understood to be Hydrogens lower energy density?
For example, I was wondering roughly how big of a tank of (I am assuming) liquid hydrogen would be required to match say 50 a gallon tank of diesel.

Or am I missing something here?
