Clean coal technology development in China

Coal is found in huge amounts throughout the world and is expected to play a crucial role as an abundant energy source. However, one critical issue in promoting coal utilization is controlling environmental pollution. Clean coal technologies are needed to utilize coal in an environmentally acceptable way and to improve coal utilization efficiency. This paper describes coal's role in China's energy system and the environmental issues related to coal use. Coal is responsible for 90% of the SO₂ emissions, 70% of the dust emissions, 67% of the NO_x emissions, and 70% of the CO₂ emissions. But as the most abundant energy resource, it will continue to be the dominant energy supply for a long time. Therefore, the development and deployment of clean coal technologies are crucial to promote sustainable development in China. Clean coal technologies currently being developed in China are described including high efficiency combustion and advanced power generation technologies, coal transformation technologies, IGCC (integrated gasification combined cycle) and carbon capture and storage (CCS). Although China only recently began developing clean coal technologies, there have been many successes. Most recent orders of coal-fired power plants are units larger than 600 MW and new orders for supercritical and ultra supercritical systems are increasing rapidly. Many national research programs, industrial research programs and international collaboration projects have been launched to develop on IGCC and CCS systems in China. Finally, suggestions are given on how to further promote clean coal technologies in China.

Coal chemical industry and its sustainable development in China

China is rich in coal resource, which is vital for energy security in this country. In early 21st century, the coal chemical industry in China will be oriented to the development of high efficiency, safety, cleanliness, and optimum utilization. In this review, the authors present an introduction to the utilization status of primary energy production and consumption in China. Since 2005, fundamental research studies, supported by the Ministry of Science and Technology of Chinese National Basic Research Program, have been carried out at Taiyuan University of Technology. The Ministry stresses that the new coal chemical industry should be developed in a sustainable manner to realize effective utilization of energy. Moreover, upgrading the high technology to improve actively the recycling processes of coal chemical engineering is of strategic importance to realize the modern coal chemical engineering.     

Residual coal exploitation and its impact on sustainable development of the coal industry in China

Although China owns large coal reserves, it now faces the problem of depletion of its coal resources in advance. The coal-based energy mix in China will not change in the short term, and a means of delaying the coal resources depletion is therefore urgently required. The residual coal was exploited first with a lower recovery percentage and was evaluated as commercially valuable damaged coal. This approach is in comparison to past evaluations when the residual coal was allocated as exploitation losses. Coal recovery rates, the calculation method of residual coal reserves and statistics of its mines in China were given. On this basis, a discussion concerning the impacts on the delay of China's coal depletion, development of coal exploitation and sustainable developments, as well as technologies and relevant policies, were presented. It is considered that the exploitation of residual coal can effectively delay China's coal depletion, inhibit the construction of new mines, redress the imbalance between supply and demand of coal in eastern China, improve the mining area environment and guarantee social stability. The Chinese government supports the exploitation technologies of residual coal. Hence, exploiting residual coal is of considerable importance in sustainable development of the coal industry in China.
