and that a sustained program of RDD&C for coal technologies is important for the economic, environmental, and security interests of the United States.
The strategic planning framework identified two priority areas for the DOE coal program: (1) conversion of coal to electricity, representing the principal market for coal for all planning periods, but particularly in the mid- to long-term periods; and (2) conversion of coal to liquid and low- and medium-Btu gaseous fuels, in the mid to long-term. EPACT requirements for coal use emphasize the need for high-efficiency, low environmental impacts, and competitive costs. These needs are generally consistent with DOE's objectives for coal RDD&C, as defined in the most recent planning documents (DOE, 1993a, 1994a). The DOE planning horizon, however, currently extends only to 2010. Specific objectives have been formulated for that period for advanced power systems and advanced fuel systems. These objectives are discussed below in the sections on electric power generation and clean fuels from coal.
Coal preparation—or cleaning—is a widely used commercial process for removing mineral matter from as-mined coal to produce a higher-quality product.
