EPRI Studies

Not all of the gas is wasted. About 300 MW of electricity is generated from landfills. A variety of electric generation systems have been employed by a small number of developers. Most projects use simple technology and are small (2—10 MW). However, an EPRI study has estimated that landfill gas resources in the United States could support 6,000 MW of generation if utilized in 2-MW-sized carbonate fuel cells. Constmction on the world s first utihty-scale direct carbonate fuel cell demonstration was begun in California. If successful, EPRI estimates that precommercial 3-MW plants based on this design could become available by the end of this decade at an installed cost of 17,000/kW. 

In the EPRI Study, a bottom-up approach was developed to define sites and applications where distributed generation may piovide high value. Methods first were developed with the cooperation of Ihe Los Angeles Dept, of Water Power (LADWP). These were tested and refined with the assistance of South West Corporation (CSW) and Oglethorpe Power Corporation (OPC). In the OPC study, the methodology used applied not only to fuel cells, but also to distributed diesels and batteries. More detail is given in the D. Rasller reference listed.

EPRI studies estimate that larger optimized plants with General Electric 7F combustion turbines and steam reheat will have a summertime heat rate of about 8,800 Btu/kWh (35). 

EPRI Studies. The Electric Power Research Institute (EPRI) has sponsored a number of engineering and economic studies of the conventional dry ash Lurgi coal gasification process. Economic and technical analyses have been completed for the following applications ... 

EPRI Studies. Except for a char gasification test in Spain (5), EPRI has not sponsored any studies specifically for the K-T technology. Published economic analyses for the K-T gasifier appear in two Tennessee Valley Authority (TVA) studies of fuel gas from coal (6,8). 

EPRI Studies. In 1987, EPRI contracted with Fluor Daniel and Destec to conduct a detailed technical and economic analysis of IGCC power generation based on 400-MW plants for both Texas lignite and Wyoming subbituminous coal (9). Central and South West Services, Houston Lighting and Power, Texas Utilities Electric Company, and the Salt River Project also participated in this analysis. 

EPRI of Skin. - The behaviour of free-radical probes in skin is an ideal target for study by EPRI because (a) the primary focus of interest is the spatial variation through the depth of the skin, so that one-spatial-dimensional EPRI studies can be performed, and (b) the small thickness of the skin ( 1 mm) means... 

Ihe purpose of the EPRI study was to identify any processes (expected to be commercially available around 1997) that might offer such significant benefits over advanced FGD/SCR that they would merit R D support. The project initially developed a list of 70 processes. This list was reduced to about 25 processes in the first screening, and 19 of these were finally selected for more detailed technical and economic evaluation. These 19 have been classified into 6 groups as indicated in Table 10-20 (Cichanowicz el al., 1991).
