Hydrogen sources...
Hi All
There are options appearing all the time if we want hydrogen - biomass, reformed natural gas, seafloor clathrates [for the methane], gasifying old coal fields [lots of energy there, just not super clean] and so forth.
As for storing it - there's the possibility of using sodium borohydride which releases its hydrogen with ajust a bit of coaxing, and can then be recycled. Heck we could even use nanotubes once industrial quantities can be made.
Simply put... hydrogen gives us more options than oil.
