We analyse how carbon emissions are reduced utilizing the new NordLink cable between Norway and Germany, taking policy plans of platform electrification in Norway into account. Building a stochastic model based on existing data for Norwegian and German electricity production and demand (Open Power system data, 2020) to account for uncertainty, we found that the cable can be used as an effective way to reduce German emissions by exporting German renewable surplus production on windy days to Norway and importing from Norway other days. We found that such flow of power will lead to a possible reduction of the countries’ total emissions by over 4.1 million tons CO${}_2$ annually. Based on a mean reduction of German CO${}_2$ emissions of about 710 g/kWh by electricity imported from Norway, we found that electrification of the Norwegian oil and gas extraction is inferior to an increased export to Germany in terms of total emission reduction, as electrification only gives a reduction of about 425 g/kWh according to numbers from the Norwegian Oil Directorate (Oljedirektoratet, 2020). A similar calculation assuming a realistic full electrification of the platforms only gave a reduction of 2.4 million tons CO${}_2$ annually. In the long term, we conclude that combining both approaches makes the best use of Norwegian surplus energy production in view of carbon emission reduction.

我们分析了如何利用挪威和德国之间的新 NordLink 电缆减少碳排放，同时考虑到挪威平台电气化的政策计划。基于挪威和德国电力生产和需求的现有数据（Open Power system data, 2020）建立随机模型来解释不确定性，我们发现电缆可以作为通过出口德国可再生能源盈余来减少德国排放的有效方法在有风的日子生产到挪威，其他日子从挪威进口。我们发现，这种电力流动将可能使这些国家的总排放量减少超过 410 万吨 CO${}_2$每年。基于德国 CO 的平均减少量${}_2$从挪威进口的电力的排放量约为 710 g/kWh，我们发现挪威石油和天然气开采的电气化在总减排量方面不如增加对德国的出口，因为电气化仅减少了约 425 g/ kWh 根据挪威石油局 (Oljedirektoratet, 2020) 的数据。假设平台完全电气化的类似计算仅减少了 240 万吨 CO${}_2$每年。从长远来看，我们得出结论，结合这两种方法可以最大限度地利用挪威的剩余能源生产，以减少碳排放。
