Abstract : Coal-water slurry fuel is a fuel that is domestic, in large supply, can be handled like a liquid, burns like coal, costs like coal, and has the potential as a near term alternative to No. 6 fuel oil. Unlike the coal gasification and liquefication processes, the capital investment required is modest. While those synthetic fuel processes cost in the order of $4 billion for a 50,000 barrel per day manufacturing facility, a coal-water plant of that size is estimated at abut $80 million (one fiftieth). While the cost of synthetic fuels has been projected at about double that of oil, the costs for coal-water are estimated at 30% to 40% less than oil. Put another way, assuming a 4% energy loss in the coal-water slurry, the resulting fuel cost of the CWM is approximately $3/million BTU. This can be compared to oil at $29/barrel or approximately $5/million BTU. The successful introduction of coal slurry technology into the marketplace as a replacement for oil has very significant potential. The hand-in-hand development of advanced coal cleaning technologies could allow the U.S. to make an economical and rapid transition away from our least abundant resource-oil-to our most abundant resource-coal. Coal-based slurries hold the promise of truly being the fuel of the 80's and beyond.
