Cogeneration Technology Alternatives Study (CTAS). Volume II. Comparison and evaluation of results
The specific objectives of the overall CTAS effort were: (1) to identify and evaluate the most attractive advanced energy conversion systems, for implementation in industrial cogeneration systems between 1985 and 2000, that could permit increased use of coal or coal-derived fuels, and (2) to quantify and assess the advantages of using advanced systems in industrial cogeneration. CTAS was concerned exclusively with providing technical and economic comparisons and evaluations of advanced systems as applied to industrial cogeneration rather than with evaluating the merits of the cogeneration concept. At the request of DOE, nine types of energy conversion systems were evaluated in CTAS: (1) steam turbines, (2) diesel engines, (3) open-cycle gas turbines, (4) combined gas turbine/steam turbine cycles, (5) Stirling engines, (6) closed-cycle gas turbines, (7) phosphoric acid fuel cells, (8) molten carbonate fuel cells, and (9) thermionics. Each type of system was examined with a variety of fuels and over a range of parameters and levels of technological advancement that could be made available for implementation between 1985 and 2000. In addition, for the steam turbine, diesel engine, open-cycle gas turbine, and combined-cycle systems, cogeneration results for technology levels and fuels representative of current commercially available equipment were estimated in order to serve as a baseline for evaluating the advantages of advanced systems. The systems were examined in cogeneration applications in a wide variety of representative industrial process plants selected from the highest energy-consuming industries.
