Carbon capture aims to reduce the amount of carbon dioxide being emitted into the atmosphere. This carbon dioxide can then be either stored or used (for example, as a chemical feedstock). Most studies have focused on carbon dioxide emissions from power generation. Psarras et al. instead estimate the cost of carbon capture from the industrial sector, which contributes almost a quarter of carbon dioxide emissions. By accounting for separation, compression, and transport costs and linking industrial sources to locations for current and potential future carbon dioxide use, they find that the overall cost of reducing carbon emission is lower for industrial sources than for power generation; costs are lowest for steel and cement manufacturing.
