資料簡介

天然氣基負荷發(fā)電具有生命周期溫室氣體排放42至53 低于燃煤基負荷電力的百分比，在占很大范圍之后在不同氣候影響時間假設(shè)下的變異性和比較。低排放因為天然氣主要是由于目前船隊平均效率的差異——53% 天然氣與煤的比例為35%，而煤的單位能量含碳量高于天然氣。甚至使用非常規(guī)的天然氣，來自致密砂、頁巖和煤層，以及與20年的全球變暖潛力（GWP）相比，天然氣發(fā)電有39 使用電流的每兆瓦時（MWh）溫室氣體排放量比煤低百分之幾技術(shù)

Natural gas-fired baseload power production has life cycle greenhouse gas emissions 42 to 53 percent lower than those for coal-fired baseload electricity, after accounting for a wide range of variability and compared across different assumptions of climate impact timing. The lower emissions for natural gas are primarily due to differences in the current fleets’ average efficiency – 53 percent for natural gas versus 35 percent for coal, and a higher carbon content per unit of energy for coal than natural gas. Even using unconventional natural gas, from tight sands, shale and coal beds, and compared with a 20-year global warming potential (GWP), natural gas-fired electricity has 39 percent lower greenhouse gas emissions than coal per delivered megawatt-hour (MWh) using current technology
