Indirectly-Fired Systems

The FE R&D program has supported this technology through two programs: EFCC (externally fired combined-cycle) and HIPPS (high-performance power system). A demonstration of EFCC technology at the 47-MW level is planned for Round V of the CCT program. Continuation of development work on HIPPS is proposed for FY 1995, with a goal of achieving 47 percent thermal efficiency (DOE, 1994b). If the HIPPS technology is to advance to the demonstration phase, the components that will be demonstrated in the CCT EFCC project must prove to be commercially viable. Thus, demonstration of HIPPS technology must await the outcome and economic evaluations of the EFCC demonstration.

Advanced Pulverized Coal Systems

As noted in Chapter 7, the FE R&D program is supporting the development of the low-emission boiler system with the goal of demonstrating a 42 percent efficient system with emissions one-half to one-third of the NSPS by the year 2000. For FY 1995, the FE R&D program has requested $7.6 million to continue engineering development and subsystem testing of this technology.

Fuel Cells

Development and demonstration of fuel cell technology have been transferred from the coal component of the FE R&D program to the gas component, on the basis that technology demonstration and commercialization will likely be accelerated using gas rather than coal. An IGCC demonstration selected in CCT Round V will utilize a portion of the clean coal gas to fuel a 2.5-MW molten carbonate fuel cell.

FUTURE DIRECTIONS

Additional CCT Solicitations

Section 1321 of EPACT requires DOE to conduct additional solicitations for the development of cost-effective, higher-efficiency, low-emission coal utilization technologies for commercialization by 2010. Recommendations for the future of the CCT program have been made by two groups, the CCTC and the NCC.

The CCTC, representing the coal, utility, manufacturing, design, and construction industries and states, advocates the demonstration of clean coal technologies and has made recommendations to DOE regarding the future of the CCT program (CCTC, 1993). The CCTC seeks to ensure that technologies demonstrated in whole or in part through the existing CCT program are also commercially deployed and thereby made ready for ''commercial application" as required
