Life cycle analysis and choice of natural gas-based automotive alternative fuels in Chongqing Municipality,China

Road transport produces significant amounts of emissions by using crude oil as the primary energy source. A reduction of emissions can be achieved by implementing alternative fuel chains. The objective of this study is to carry out an economic, environmental and energy (EEE) life cycle study on natural gas-based automotive fuels with conventional gasoline in an abundant region of China. A set of indices of four fuels/vehicle systems on the basis of life cycle are assessed in terms of impact of EEE, in which natural gas produces compressed natural gas (CNG), methanol, dimethylether (DME) and Fischer Tropsch diesel (FTD). The study included fuel production, vehicle production, vehicle operation, infrastructure and vehicle end of life as a system for each fuel/vehicle system. A generic gasoline fueled car is used as a baseline. Data have been reviewed and modified based on the best knowledge available to Chongqing local sources. Results indicated that when we could not change electric and hydrogen fuel cell vehicles into commercial vehicles on a large scale, direct use of CNG in a dedicated or bi-fuel vehicle is an economical choice for the region which is most energy efficient and more environmental friendly. The study can be used to support decisions on how natural gas resources can best be utilized as a fuel/energy resource for automobiles, and what issues need to be resolved in Chongqing. The models and approaches for this study can be applied to other regions of China as long as all the assumptions are well defined and modified to find a substitute automotive energy source and establish an energy policy in a specific region.     

南水北调中线不同调水方案下的汉江水华发生概率分析

为评估南水北调中线工程对汉江中下游水华的影响，从汉江水华的成因机理分析入手，提出了汉江水华发生概率的计算模型．该模型由河流一维水动力学模型、水体富营养化模型以及随机数生成模型组成，它不仅可以模拟汉江水华的发生机理，而且可以对诱发水华的各种因子进行随机抽样组合，从而求出中线调水不同方案实施后汉江水华的发生概率．计算结果表明，在现状情况下汉江水华的发生概率为9．2％，南水北调中线各调水方案（无引江济汉工程）实施后，汉江水华发生的概率将有一定程度的增加，而如果调水方案与引江济汉工程同时兴建将大大减少汉江水华发生的概率．最后提出建议，汉江自身的水污染治理是减少水华发生概率的最根本措施，而丹江口水库和引江济汉工程的联合调度将会减小汉江水华发生的概率．
