hyderabad: experts at a seminar on friday suggested that the country should go in for "supercritical and ultra-supercritical" power plants as they provided many advantages, including reduced costs, and not polluting the environment. they said such plants would reduce by 15 per cent the emissions of carbon dioxide, when compared with the existing sub-critical plants.
in order to adopt the supercritical technology for high ash indian coals, some important issues like development of high temperature creep resistant alloy steels and alternative boiler technology for gasification cycles, need to be thrashed out, they said. prof d n reddy, director of the centre for energy technology,osmania university college of engineering, which organised the seminar, said india had considerable potential for new generation capacity based on coal.
