coal fired Power Industry water energy emission nexus a multi objective optimization
Journal of Cleaner Production, 2018Co-Authors: Chunyan Wang, Gustaf Olsson, Yi LiuAbstract:Abstract The Chinese government has launched a guideline to lead Power plants to more suitable technological pathways for meeting the strict “ultra-low emission” (“ULE”) standards to reduce air pollution emissions of the coal-fired Power Industry. Considering the complex interrelations between water, energy and emission, a quantifiable method of choosing the feasible technology sets for 6 multi-objective optimizations goals (MOGs) in the concept of water-energy-emission nexus (WEEN) was developed in this study. The results showed that the 16 technology sets can meet the “ULE”, which could mitigate at least 72% of the current emissions at the cost of up to 17% increase of water/energy consumption. Specific technology sets were identified for 6 different MOGs with the coordinate consideration of WEEN. The comparisons among the 6 MOGs indicated that (1) the investment cost was not a vital factor in the optimizing procedures; (2) dust reduction was sensitive to the water/energy optimization goal due to the synergic dust removal effects of the desulfurization technologies; (3) the water for WEEN was easier to reduce than the energy for WEEN from the perspective of the tradeoffs of emissions. The identified 12 feasible technology sets for WEEN (-cost) would shed lights on more coordinately policy making process.

investigation of water energy emission nexus of air pollution control of the coal fired Power Industry a case study of beijing tianjin hebei region china
Energy Policy, 2018Co-Authors: Chunyan Wang, Yi LiuAbstract:Coal-fired Power generation is water- and energy-intensive and is associated with high emissions. As a result, China has issued a strict emission policy ("ultra-low emission control") for the coal-fired Power Industry. This study investigated the water, energy and emissions nexus (WEEN), focusing on end-of pipe treatment technologies for the coal-fired Power Industry in the Beijing-Tianjin-Hebei region. The result revealed that the energy consumption for pollutant removal was 1.2 million tons coal equivalent (Mtce) for the 118 investigated plants in 2014. Of the energy consumed, 60%, 11% and 29% was used for SO2, NOx and dust removal, respectively. Water consumption for pollutant removal was 13% of total water consumption for electricity generation. The result implied that this policy could reduce SO2, NOx and dust emissions by 89%, 90%, and 88%, respectively, while consuming an average of 2% less energy and 8% more water as tradeoffs. Construction cost associated with implementing these technology changes could be as high as 5–14 billion yuan in total. The synergies and tradeoffs quantified in this study provide numerical information that could assist with making decisions on the most suitable technology sets for emission control with consideration of water, energy, emissions and cost.

is there a difference between the energy and co2 emission performance for china s thermal Power Industry a bootstrapped directional distance function approach
Applied Energy, 2016Co-Authors: Na Duan, Junpeng Guo, Baichen XieAbstract:Abstract A scientific evaluation of the energy efficiency and CO2 emission performance of the thermal Power Industry could not only provide valuable information for reducing energy consumption and carbon emissions but also serve as a tool to estimate the effectiveness of relevant policy reforms. Considering the opposite effects of energy conservation and carbon emission reduction on generation cost, this study respectively measures the energy and CO2 emission performance of the thermal Power industries in China’s 30 provincial administrative regions during the period 2005–2012 from both static and dynamic perspectives. We implement the bootstrap method for the directional distance function to correct the possible estimate bias and test the significance of productivity changes where the weak disposability of undesirable outputs is also integrated. The empirical analysis leads to the following conclusions. The bootstrapping results could provide us with much valuable information because the initial estimates might result from sampling noise rather than reveal the real variations. In addition, some differences do exist between the energy and CO2 emission performance of China’s thermal Power Industry. Furthermore, technological progress is the main driving force for energy and CO2 emission productivity improvement and it works better for the former.

performance of wind Power Industry development in china a diamondmodel study
Renewable Energy, 2009Co-Authors: Zhen Yu Zhao, Jian ZuoAbstract:Abstract A reliable supply of energy is essential to maintain and to improve human being's living conditions. Compared to the conventional coal-fired approach, renewable energy (RE) helps to mitigate the impacts of greenhouse gas emissions to a large extent. As a newly developed sector with large resource potential and good commercial prospects, China's wind Power Industry is exceeding expectations. By 2008, installed capacity of wind Power in China totaled over 12 GW, making China the fourth largest wind market in the world. However, China has to admit the gap with foreign leading countries, mainly in technical R&D for large-scale wind turbine generation units. This paper attempts to formulate an analytical model for studying and assessing factors that have significant impacts on the local Industry. An improved dynamic Diamond Model is developed to help the international community to understand the status quo of the Chinese wind Power Industry. In order to build a stronger wind Power Industry, the elements identified in the model need to be strengthened.
