capacity in the past. A pilot light which goes out could
result in a greater potential safety hazard than methane alone.
Another existing transport mode is the electric transmission
system. The East North Central U.S. has an extensive grid
system which should provide for relatively inexpensive access.
An example of such a grid network was supplied by the American
Electric Power Service Corporation, see Figure 3.8-13. Again,
the use of modular gas turbine combined cycle or co-generation
power systems appears to have certain advantages over other
uses for UCG derived gases.
3.8.2.4 Site Specific Markets
It is evident from the discussion in the previous sub-sections
that a UCG facility located in the East-North-Central region of
the U.S. should not be far from an industrial base. However,
the low economic transportation radius of a low BTU gas may
limit distribution to less than 50 miles. Medium BTU gas,
particularly with the carbon dioxide removed, should be able to
exceed this limit as indicated in the previous section.
In order to try to identify site specific markets a search was
made within a 50 mile radius of each of the fifteen (15)
originally defined potential target areas. Only existing fuel
users in the industrial and utilities categories were
identified. Site specific possibilities of attracting
industries into an industrial park complex or the need for
additional intermediate load power in the future was not
investigated and should be the subject of a future study. The
residential market was not reviewed as it was felt that this is
not a viable market although it will benefit indirectly from
any natural gas tradeoff.
To simplify the analysis only potential markets for low and
medium BTU fuel gas were investigated. The chemical market was
not addressed due to the difficulty of obtaining meaningful
data without investigating each plant in detail to determine
raw material requirement.
Each of the fifteen target areas previously selected on the
basis of geological considerations was tested for market
potential by using available data and applying a marketing
criterion. The criterion requires only that at least one
existing fossil fuel consumer big enough to support a
230 MMBTU/hr UCG facility be located within 50 miles of the
selected target area. This criterion assumes that an existing
industry would be willing to switch or incorporate fuel gas
from a UCG facility when it became available.
A 230 MMBTU/hr facility is roughly equivalent to a 3.5 MM ton
resource utilized over a 20 year period. While the economics
