资料简介

天然气基负荷发电具有生命周期温室气体排放42至53 低于燃煤基负荷电力的百分比，在占很大范围之后在不同气候影响时间假设下的变异性和比较。低排放因为天然气主要是由于目前船队平均效率的差异——53% 天然气与煤的比例为35%，而煤的单位能量含碳量高于天然气。甚至使用非常规的天然气，来自致密砂、页岩和煤层，以及与20年的全球变暖潜力（GWP）相比，天然气发电有39 使用电流的每兆瓦时（MWh）温室气体排放量比煤低百分之几技术

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
