| A Comparative Analysis of Life-cycle Greenhouse Gas Emission between Lignite-based Synthetic Natural Gas Production and Power Generation |
| China has relatively abundant lignite, which is mainly distributed in eastern Inner Mongolia, Yunnan Province and Heilongjiang Province. Traditionally, the thermal power generation is the predominant way to use lignite; nevertheless, it is also the way with low energy utilization rate and high pollution. In addition to power generation, new technologies dealing with lignite have matured. Lignite-based synthetic natural gas production and power generation with lignite upgrading technology are of representativeness. Based on Life Cycle Assessment, this paper compared the Greenhouse Gas (GHG) emissions of 1GJ output of effective energy between lignite-based Synthetic Natural Gas (SNG) production and power generation with lignite upgrading technology under the condition of the same energy efficiency of end use. They are respectively 158.173/e kg/GJ, 480.68/e kg/GJ (e as the energy efficiency of end use). Obviously, the life cycle GHG emission of lignite-based SNG production is significantly less than that of the upgraded lignite-power generation. |
