Why not both sustainable and cheapest? Hydrogen doesn't compare
well to something like biodiesel when it comes to storing,
transporting, making or using the stuff.


Hydrocarbon fuels are already energy dense, can be sustainable
and exist today and not in fifty years time.

How can they be sustainable if consumption is high and reserves
finite ?

You can grow plants so therefore you can grow biofuels. You can
even grow plants (and therefore biofuels) sustainably.

You can in some parts of the world, but if we go that way, I major
changes to agricultural land use will be needed.

You wouldn't need major changes to agricultural land use if your
fuel crop does not use agricultural land. One of the best candidates
for a fuel crop is algae which can grow in salt water.

By definition, any concept that involves changing the entire worlds
supply of energy is going to be major. :)
