The report examines the future supply and demand of low sulfur fuel oil. Of all the fuels, residual oil (resid, No. 6, or 'Bunker C') was the most difficult to study. The currently available predictions on the supply and demand for electricity and fuels were collected and studied. Construction plans of the utilities were obtained. Data on United States and foreign production of residual oil were gathered including the availability of low sulfur fuel. Total demand for residual fuel was predicted along with the demand for low sulfur fuels. The potential supply of low sulfur fuels was predicted. The effects that import regulations have on this supply was studied. The costs of direct desulfurization of resid were estimated along with the costs of oil transportation. The supply and demand quantities for residual oil were compared for the 1970-1980 time period and conclusions were drawn as to what steps must be taken to satisfy the 1980 demand for low sulfur fuels.
