To fulfill this assignment, GFETC must: (1) identify the properties of low-rank coals that affect the applicability and economics of technologies (2) identify R and D needs unique to low-rank coals, and establish priorities based on potential impact on expanded development and (3) ensure that DOE's coal R and D programs address those needs. The study is being directed by the Grand Forks Energy Technology Center (GFETC), which has the lead mission within the Department of Energy for technology applications for low-rank coals. These properties include high moisture content, dispersed alkaline mineral matter content, high more » reactivity, and low sulfur content. This will require technological improvements and developments to solve unique problems associated with the physical and chemical properties of low-rank coals. Utilization of these fuels has expanded rapidly in recent years and will continue to expand in line with national energy priorities. The primary objective is to propose a comprehensive national R and D program focusing on technology development for enhanced utilization of lignite and subbituminous coal. « lessĪn analysis of the technical, environmental, and economic constraints to expanded development of the US, low-rank coal resource is in progress. EPRI's CoalFleet for Tomorrow program is also preparing a companion RD&D augmentation plan for advanced-combustion-based (i.e., non-gasification) clean coal technologies (Report 1013221). Summaries of ongoing research projects on low-rank coals in the US are presented in an Appendix, and the relationships of these ongoing efforts to the recommended RD and D program are = capture. The recommended RD and D activities are classified into Priority I and Priority II categories, reflecting their relative urgency and potential impact on the advancement of low-rank coal development.

Basic research topics are identified separately, as well as a series of crosscutting research activities addressing environmental, economic, and regulatory issues. RD and D project recommendations are outlined in all applicable technology areas, including extraction, transportation, preparation, handling and storage, conventional combustion and environmental control technology, fluidized bed combustion, gasification, liquefaction, and pyrolysis. A national program is recommended for research, development, and demonstration (RD and D) of improved technologies for the enviromentally acceptable use of low-rank coals.
