Adapting sustainable low-carbon techologies to reduce carbon dioxide emissions from coal-fired power plants in China.

摘要

The scientific community is deeply concerned about the effect of greenhouse-gases (GHGs) on global climate change. A major climate shift can result in tragic destruction to our world. Carbon dioxide (CO{dollar}sb2{dollar}) emissions from coal-fired power plants are major anthropogenic sources that contribute to potential global warming. The People's Republic of China, with its rapidly growing economy and heavy dependence on coal-fired power plants for electricity, faces increasingly serious environmental challenges.; This research project seeks to develop viable methodologies for reducing the potential global warming effects and serious air pollution arising from excessive coal burning. China serves as a case study for this research project. Major resolution strategies are developed through intensive literature reviews to identify sustainable technologies that can minimize adverse environmental impacts while meeting China's economic needs. The research thereby contributes technological knowledge to the field of Applied Sciences. The research also integrates modern power generation technologies with China's current and future energy requirements.; With these objectives in mind, this project examines how China's environmental issues are related to China's power generation methods. This study then makes strategic recommendations that emphasize low-carbon technologies as sustainable energy generating options to be implemented in China. These low-carbon technologies consist of three options: (1) using cleaner fuels converted from China's plentiful domestic coal resources; (2) applying high-efficiency gas turbine systems for power generation; and (3) integrating coal gasification processes with energy saving combined cycle gas turbine systems. Each method can perform independently, but a combined strategy can achieve the greatest CO{dollar}sb2{dollar} reductions.; To minimize economic impacts caused by technological changes, this study also addresses additional alternatives that can be implemented in parallel with the proposed technologies. Principal options include promoting wind, solar and biogas as alternative energies; encouraging reforestation; using economic incentives to change energy policies; and gradually replacing obsolete facilities with new power plants. This study finds that the limited capacity and associated costs of alternative energies are the main factors that prevent competition with coal-based energy in China today.
