DES/CCHP: the best utilization mode of natural gas for China's low carbon economy / Yajun Li; Xia, Yan   Journal Article
Yajun Li Journal Article
0 Rating(s) & 0 Review(s)
Publication 2013.
Summary/Abstract In this paper, through the analysis of the great challenges faced by China's energy industry in the development of low carbon economy, it is advisable that China increase the proportion of natural gas (NG) in primary energy as the main strategy of energy conservation and CO2 reduction in the advancement of industrialization and urbanization. In the near future, NG will become one of the major energy suppliers for new towns and industrial parks, and work for electric peak shaving when used in distributed energy system/combined cold, heat and power (DES/CCHP). However, as an efficient approach to improve the energy utilization efficiency, DES/CCHP cannot only increase the current energy efficiency from 33% to 50.3% (the world's average), but also reduce the cost of terminal supplies of power, cold, steam and hot water. It will become one of the most important means to control CO2 emissions in the next 20 years, and is essential to China's low carbon industrialization and urbanization.

Policy study examining the use of imported LNG for gas-fired po / Yajun Li; Bai, Fangfang   Journal Article
Yajun Li Journal Article
0 Rating(s) & 0 Review(s)
Publication 2010.
Summary/Abstract Since China's energy demand is growing quickly, speeding up the development of natural gas is an important substitute and supplement for coal and oil. The development of the natural gas market in many developing countries has demonstrated that the success of the whole project hinges upon the success of gas-fired power generation. However, under the current energy pricing system in China, the advantages of gas-fired power plants, such as low investment costs and high efficiency, have not been able to offset the low price of coal. The gas-fired power plants, both at downstream of the Liquefied Natural Gas (LNG) industry and upstream of the power sector, are faced with a dilemma. In order to solve the problems facing gas-fired power projects while providing policy guidance for the future development of gas-fired power projects, the policy of gas-fired power generation using imported LNG on the southeastern coast of China was examined. This study aims to identify the position of the national energy strategy that China should import some LNG from the other countries, to guide the development of energy policy in this region, and to formulate some clear policy measures.
