The economics of hydrogen production depend on the efficiency of the
method used. The IS cycle coupled to a modular high temperature
reactor is expected to produce hydrogen at $1.50 to $2.00 per kg. The
oxygen by-product also has value.

For thermochemical processes an overall efficiency of greater than 50%
is projected. Combined cycle plants producing both H2 and electricity
may reach efficiencies of 60%.

The economics also depends on the economics of battery storage
systems, and the cost of fuel for internal combustion engines, and the
cost of fuel cell powered vehicles. Leaving aside ICE's, which we
probably agree are an undesirable long term power source for vehicles,
current battery technology would make all but thermochemical processes
uneconomic, even if someone can produce an economic fuel cell powered
vehicle.

Advances in battery economics will probably make the whole hydrogen
issue irrelevant, event with thermo chemical processes.

In other words, which is more likely:
- The cost of batteries will halve and the performance improve by
about 50%; or
- The cost of fuel cells will fall by 90% and the world will rush to
build high temperature nuclear reactors and a hydrogen production and
distribution capability.
