These enhance national energy security and are among the cleanest, ecologically safest coal utilization technologies. This paper delineates the major characteristics of such technologies and analyzes technical solutions. Highlighting the desire to develop large scale industrial UCG plants, pilot level projects are presented using a new UCG method developed in Russia by Joint Stock Company Gazprom Promgaz. This method is distinct for its high controllability, stability, and energy efficiency. New, efficient technical solutions have been developed over the last 10-15 years and are patented in Russia. They guarantee controllability and stability of UCG gas produc- tion. Over one hundred iniection and gas production wells have been operated simultaneously.展开更多

As China＇ s natural gas production drops and its demand for clean energy sources, such as natural gas, grows, LNG, as a complement to piped natural gas, will be an important part of China＇s strategy of ensuring its natural gas consumption. Aware of this market opportunity , China＇s three big national oil companies, CNPC, CNOOC and Sinopec have all inw＇sted in Australia＇s LNG sector. Chinese oil companies are facing multiple challenges in their Australian LNG projects, including strict environmental taws and high labor cost. These companies should strengthen communication with local government to create a good investment environment for LNG projects.展开更多
