Polygeneration Energy System Based on Oxygenblown Coal Gasification

Environmental pollution has become the bottlenecking of the sustainable economic development of China. The business-as-usual energy system in China is not suitable for sustainable need. It is well known that China has to use coal as the main primary energy for quite a long term. Under such special conditions, it is an urgent strategic problem to be studied and carried out step by step from now on to plan and construct the integrated sustainable energy system with optimal benefits in resource and energy utilization and environmental emission. By introducing the international study and new development in sustainable energy systems, this paper put forward that poly-generation strategy based on coal gasification is the trend for future development of our domestic energy industry. The framework of polygeneration system based on oxygen blown gasification is described and its benefits are analyzed. Finally, the starting procedure, government role and policies for the implementing of poly-generation strategy in China are proposed.
