Energy and cost savings results for advanced technology systems from the Cogeneration Technology Alternatives Study (CTAS)
An overview of the organization and methodology and a summary of selected results to date of the Cogeneration Technology Alternatives Study (CTAS) are presented. The objectives of the study are to identify the most attractive advanced energy conversion systems for industrial cogeneration applications in the 1985 to 2000 time period and to assess the advantages of advanced technology systems compared to those systems commercially available today. Advanced systems being studied include steam turbines, open and closed cycle gas turbines, combined cycles, diesel engines, Stirling engines, phosphoric acid and molten carbonate fuel cells and thermionics. Steam turbines, open cycle gas turbines, combined cycles, and diesel engines are also being analyzed in versions typical of today's commercially availably technology to provide a base against which to measure the advanced systems. Cogeneration applications in the major energy consuming manufacturing industries are being considered. Results of the study in terms of plant level energy savings, annual energy cost savings and economic attractiveness are presented for the various energy conversion systems considered. Sensitivity of the results to variations in assumed study groundrules such as fuel prices and the price of purchased electricity and the potential effect of regional characteristics are discussed.
