Great! However, the big question that very few people seem to be able

answer (myself included) is where the energy to make the H2 should come
from?

Natural gas. Mix methane (CH4) and very hot steam (H20) to produce Carbon
Dioxide (CO2) and Hydrogen (H2). This is a very well known process, and is
(was?) commonly used in the industrial production of chemicals.


Why not just use the methane directly and not incur
all the losses conversion brings with it ?
