For the same reason, mine-mouth conversion of coal to solvent-refined coal, methanol, or synthetic crude is usually also favored logistically and economically over transport of coal plus conversion at the destination. However, the cost advantage can be greatly reduced if the cost of constructing a synfuels facility is larger at the source than at the destination. For example, installed-plant costs in Wyoming may be 40% larger than those for a similar plant erected in Texas.
