Dr John Topper, Managing Director of the IEA CCC has recently returned from a trip to India (25 Nov – 2 Dec 2011). The purpose of his trip was three-fold: to support the IEA’s activities in compiling a High Efficiency, Low Emissions (HELE) Coal Roadmap; to give a speech at a coal preparation conference; and to visit and share his expertise with Bharat Heavy Electricals Limited (BHEL), a sponsor member of the IEA CCC. John attended BHEL meetings in several locations, including Delhi, Chennai and Tiruchirapalli.
Against a backdrop of rising global energy demands, carbon capture and storage could enable cutting CO2 emissions by half in 2050 through a combination of existing and new technologies. This could be fulfilled by a large-scale transformation in the way energy is produced, delivered and consumed, Dr John Topper, said as part of his address to a workshop on ‘Supply and Demand of Coal and Power Plant Technology Evolution’.
Demand for coal has been growing faster than any other energy source and is projected to account for more than one-third of the incremental increase in global energy demand. To reduce CO2 emissions and increase efficiency of power generation, supercritical boilers and advanced ultra supercritical boilers are being developed in India, EU, Japan, USA, and China. In India, a date has been set for operation of an 800 MW demonstration plant, Dr John Topper said. The Executive Director of BHEL, Tiruchi, A.V. Krishnan, said the company’s research and development activities were aligned to state-of-the-art technological developments taking place world-wide. R. Kumar, General Manager, Engineering, said BHEL had contracted over 960 boilers capable of generating over 1,36,073 MW of energy, and also exported 21 steam generators. Currently, BHEL has received orders for 14 supercritical units at sizes from 600-800 MWe equivalent.
BHEL Is undertaking the practical test work at Trichy for the Indian A-USC project. The Indira Ghandi Research Institute will contribute expertise on materials. The National Thermal Power Corporation (NTPC) will provide large scale testing opportunities in due course. It is understood that, for the test work, BHEL is looking at several superalloys and at temperatures in excess of 700C and a range of tubing sizes. John Topper visited a new coal testing laboratory, where about €2 million has been invested on test and characterisation equipment. He also met a group from the Trec-Step team fron the Indian Science and Technology Entrepeneurs Parks and Business Incubators Association. They are part of an EC funded capacity building project related to Clean Coal Technologies and CCS.
