“…This was evidenced by SEM in the prepared nanocomposites ( Figure 4). The observed superior CO 2 uptake of the nanocomposites vs. the pure TiO 2 could also improve photoactivity [28] via increasing the CO 2 have also decreased the number of hetero-interfaces in the nanocomposites, which in turn disfavored charge transfer process in heterostructures [58].…”

“…CO 2 reduction may have also occurred on NH 2 -UiO-66 but to a lesser extent, as observed experimentally. In the TiO 2 /NH 2 -UiO-66 nanocomposites photoactivity was mainly governed by two parameters: (a) the content of TiO 2 that controls the available sites for CO 2…”

“…As the conversion efficiency of thermal energy to electrical energy is around 30 %, the thermal energy of the three designs varies from 4 to 4.7 MJ/kg. Traditional MEA solvent absorption of CO 2 from cement kiln gas has been estimated at a thermal energy demand of 3.7 -4.4 MJ/kg of CO 2 captured as reported by Kuramochi et al (Kuramochi et al, 2012), and 5 MJ/kg of CO 2 captured by Vatopoulos and Tzimas (Vatopoulos and Tzimas, 2012).…”

“…Calcium looping technology has been demonstrated to be relatively cheap, reflecting the lower energy duty in this application. Romeo et al (2011) reported a cost of capture of US$ 16.2 per tonne of CO 2 avoided (€ 12.4 per tonne of CO 2 avoided), Rodriguez et al (2012) quoted a cost of capture of US$ 23 per tonne of CO 2 avoided, and Kuramochi et al (2012) demonstrates calcium looping achieves a cost less than US$ 35 per tonne of CO 2 avoided (€ 27 per tonne of CO 2 avoided). These costs of capture are all less than those estimated for the membrane processes studied here.…”

The cement industry is a significant source of CO 2 emissions for the non-power sector. Carbon capture and storage has been proposed as a strategy to mitigate these CO 2 emissions. The high CO 2 partial pressure of the cement kiln flue gas enables more options than in other post-combustion capture scenarios. Here, three distinct process designs for membrane gas separation are simulated for the capture of CO 2 from cement kiln flue gas. The first design is based on a standard natural gas processing flowsheet and includes two membrane stages with a permeate recycle from the first stage. The second design uses a single membrane stage with downstream compression and cooling to achieve the necessary purity. The final design incorporates three membrane stages with similar downstream compression and cooling. It was found that the CO 2 /N 2 selectivity of the membrane strongly influenced the performance of all three processes. The third design achieved the lowest energy demand of 1.2 MJ/kg of CO 2 captured for membranes with CO 2 /N 2 selectivity above 50. Below a selectivity of 25 the second design with a single membrane stage had the lowest energy demand. However, a different trend was observed with cost of capture, where below a CO 2 /N 2 selectivity of 25 the second design provided the lowest cost of capture while above this selectivity the first design was cheapest. This design could provide a cost of capture of US$ 74 per tonne of CO 2 avoided, based on current state-of-the art membrane permselectivity, which is competitive with solvent absorption carbon capture technologies. However, calcium looping and oxyfuel combustion would appear to have lower costs in this scenario.

Industrial emissions are significant and need to be addressed in the fight against climate change. To achieve carbon emission reduction targets in line with climate change policies while maintaining the competitiveness of the industry, hard-to-abate sectors are exploring efficient carbon reduction technologies and striving to reduce associated costs. Carbon capture technology presents a large-scale CO2 reduction solution with immense potential. In promoting the application of carbon capture in hard-to-abate industries, it is essential to comprehensively analyze the feasibility and economics of carbon capture technology. This paper conducts a review of the technical feasibility and economics of carbon capture technologies in several industrial sectors, namely iron and steel, cement, and coal chemical industries. A vast amount of data on the costs of industrial carbon capture technologies has been gathered for comparison. This study also specifically addresses policy incentives that have been discussed and are currently being implemented to cut costs and promote industrial carbon capture projects. Graphical abstract
