Captured CO₂ from large industrial emitters may be used for enhanced oil recovery (EOR), but as of yet there are no European large-scale EOR systems. Recent implementation decisions for a Norwegian carbon capture and storage demonstration will result in the establishment of a central CO₂ hub on the west-coast of Norway and storage on the Norwegian Continental Shelf. This development may continue towards a large-scale operation involving European CO₂ and CO₂ EOR operation. To this end, a conceptual EOR system was developed here based on an oxyfuel power plant located in Poland that acted as a source for CO₂, coupled to a promising oil field located on the Norwegian Continental Shelf. Lifecycle assessment was subsequently used to estimate environmental emissions indicators. When averaged over the operational lifetime, results show greenhouse gas (GHG) emissions of 0.4 kg CO₂-eq per kg oil (and n kWh associated electricity) produced, of which 64 % derived from the oxyfuel power plant. This represents a 71 % emission reduction when compared to the same amount of oil and electricity production using conventional technology. Other environmental impact indicators were increased, showing that this type of CO₂ EOR system may help reach GHG reduction targets, but care should be taken to avoid problem shifting.

从大型工业排放装置中捕获的CO ₂可以用于提高采油率（EOR），但到目前为止，还没有欧洲的大规模EOR系统。挪威碳捕集与封存示范的最新实施决策将导致在挪威西海岸建立一个中央CO ₂枢纽，并在挪威大陆架上进行封存。这种发展可能会继续朝着涉及欧洲CO ₂和CO ₂ EOR操作的大规模操作发展。为此，在此基础上开发了概念性的EOR系统，该系统基于位于波兰的富氧电厂作为CO ₂的来源，再加上位于挪威大陆架上的一个有前途的油田。随后使用生命周期评估来估计环境排放指标。如果对整个使用寿命进行平均，结果表明每产生的千克油（和n kWh相关电力）产生的温室气体（GHG）排放量为0.4 kg CO ₂当量，其中64％来自于含氧燃料发电厂。与使用常规技术进行的相同数量的石油和电力生产相比，这意味着减少了71％的排放。其他环境影响指标也有所增加，表明此类CO ₂ EOR系统可能有助于实现减少温室气体排放的目标，但应注意避免问题转移。
