Economic growth in developing countries can have serious environmental impacts. In such countries as India, the development and commercialization of clean coal technologies for fossil-fuel utilities that generate electric power present a major opportunity to sustain and enhance regional and global development in an environmentally acceptable manner. The major source of power generation in India - into the 21st century - will be coal-fired boilers. Annual power growth is targeted at about 12% every year through the year 2000. This makes the growth of a reliable, economical, and environmentally sound electricity supply a formidable challenge. To meet this anticipated demand, the Indian power sector plans to install more than 100,000 MWe in additional capacity over the next decade. About 65% of these additions will be coal-fired plants, making the potential environmental impact very significant, particularly because the coals used for thermal power in India have an ash content ranging from 40 to 50% - compared with less than 20% ash in US coals. As India increases its mining operations (projected to be 400 millions tons by the year 2000) to meet increasing power-generation demands, the heating value (4,500 to 5,000 kcal/kg) will be even lower than it is today. India uses open-cast mining to access deep coal seams. Typically, there are mineral matter bands between seams. This method produces coals with decreasing calorific value and a higher proportion of dirt and shale. Run-of-mine coal is now used in utility boilers - meaning that coal is not cleaned before it is burned. India will improve its power-generation capacity by using more efficient ways to grade, clean, and burn this abundant resource. Installing and utilizing advanced coal beneficiation and other clean coal technologies will promote large-scale, efficient use of India's indigenous coals.
