That sounds very interesting. The cool thing about hydrogen of course is it is so abundant. The splitting is not hard. I have done it at home with a phone charger. The devil in the details was always the storage coz the atom of hydrogen is so small it can leak from anything. An example is how those metallic balloons leak helium over time.
I remember so much talk and so much promise about fuel cells back in the 90's. I hope we can see mass adoption before too long.
