Natural gas and CO2price variation: impact on the relative cost-efficiency of LNG and pipelines

摘要: This article develops a formal model for comparing the cost structure of two main transport options natural gas: liquefied gas (LNG) and pipelines. In particular, it evaluates how variations in prices greenhouse emissions affect relative cost-efficiency these options. Natural is often promoted as most environmentally friendly all fossil fuels, LNG modern efficient way transporting it. Some research has been carried out into local environmental impact facilities, but almost none aspects related to climate change. paper concludes that at current price levels CO2 distance from field consumer volume transported are determinants costs. The pricing influence pipeline transport, only limited degree levels. Because more energy required process (especially fuelling liquefaction process) than pipelines distances below 9100 km, exposed variability up this distance. If and/or emission rise dramatically future, will choice between LNG. Such increase be favourable
