Carbon capture and storage (CCS) is expected to play a key role to achieve deep emission cuts in the energy intensive industry sector. The implementation of carbon capture comes with a considerable investment cost and a significant effect on the plants operating cost, which both depend on site conditions, mainly due to differences in flue gas flow and composition and depending on the availability of excess heat that can be utilized to power the capture unit. In this study we map the costs required to install and operate amine-based post-combustion CO₂ capture at all manufacturing plants in Sweden with annual emissions of 500 kt CO₂ or more, of both fossil and of biogenic origin, of which there are 28 plants (including a petrochemical site, refineries, iron and steel plants, cement plants and pulp and paper mills). The work considers differences in the investment required as well as differences in potential for using excess heat to cover the steam demand of the capture process. We present the resulting total CO₂ capture costs in the form of a marginal abatement cost curve (MACC) for the emission sources investigated. Cost estimations for a transport and storage system are also indicated. The MACC shows that CO₂ capture applied to 28 industrial units capture CO₂ emissions corresponding to more than 50% of Swedish total CO₂ emissions (from all sectors) at a cost ranging from around 40 €/t CO₂ to 110 €/t CO₂, depending on emission source. Partial capture from the most suited sites may reduce capture cost and, thus, may serve as a low-cost option for introducing CCS. The cost for transport and storage will add some 25 to 40 €/t CO₂, depending on location and type of transportation infrastructure.

碳捕集与封存（CCS）有望在能源密集型行业中实现大幅减排的过程中发挥关键作用。碳捕集的实施会带来可观的投资成本和对工厂运营成本的重大影响，这都取决于现场条件，这主要是由于烟气流量和成分的差异以及取决于可利用的多余热量的可用性为捕获单元供电。在这项研究中，我们绘制了在瑞典所有制造工厂中每年排放500 kt CO _2的胺基燃烧后CO ₂捕集装置的安装和运行所需的成本图。或以上的化石和生物来源的植物，其中有28家工厂（包括石化厂，炼油厂，钢铁厂，水泥厂以及制浆造纸厂）。这项工作考虑了所需投资的差异，以及利用多余的热量来满足捕集过程的蒸汽需求的潜在差异。我们以调查的排放源的边际减排成本曲线（MACC）的形式展示了总的CO ₂捕集成本。还指示了运输和存储系统的成本估算。的MACC表明，CO ₂捕获施加于28个工业单位捕获CO ₂的排放量对应于瑞典总CO的50％以上的₂排放（来自所有部门），成本在40€/ t CO ₂到110€/ t CO _2之间，具体取决于排放源。从最合适的站点进行部分捕获可以降低捕获成本，因此可以作为引入CCS的低成本选择。运输和存储成本将增加25至40€/ t CO ₂，具体取决于运输基础设施的位置和类型。
