The purpose of this report is to evaluate the final reports prepared for 19 proposed coal gasification plants funded under the Alternative Fuels legislation. These 19 studies represented the best set of publicly available information on commercial-scale coal gasification plants. They encompassed all areas that would be relevant in determining if any of the plants should be constructed: general information business considerations, process information, cost data, and environmental considerations. The performers of the studies were awarded US Department of Energy (DOE) contracts in 1980. Study results, in the form of final reports for the feasibility studies, were returned to the Morgantown Energy Technology Center (METC), the DOE center with lead responsibility for gasification research. Data from the studies were abstracted and entered into the Major Plants Data Base (MPDB), a system developed and used at METC to aid in the analysis of design and operating data from commercial- and demonstration-scale synfuels plants. The MPDB is designed to store and retrieve data in five broad categories: general project information, process and technical information, financial and business data, capital cost information, and EHSS (environmental health, safety, and socioeconomic) data. The MPDB system was used to retrieve data and aid data analysis for this report. The evaluation of the reports was twofold. First, each study was analyzed individually to determine whether the data expected to be in the report were indeed present, and whether they were of the quality expected. Secondly, studies were compared with one another to see what conclusions could be drawn from these data. The individual evaluation of the various studies showed that, in general, the data provided were of high quality. 24 refs., 13 figs., 46 tabs.
