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

But the big problem for the eco-types is all of the C02.

If you're going to make that, you might as well just use gasoline.

Now, if this new algae-based process of making H2 works out, we'll get
H2 with a net *reduction* of C02.
