“…Hence, primary energy in the fuel can be exploited directly, accompanied with the process heat recovery 35 (see Supplementary Figure 5 ), instead of being transformed into electricity before driving any CO 2 capture processes. In consequence, the energy cost is decreased appreciably 36 and the electricity price is no longer a factor hindering deployment of such a decarbonisation option 25 . In addition, on account of integrating decarbonisation into the steelmaking process via making full use of the limestone feedstock in the CaL-LP scheme (Fig.…”

Accounting for ~8% of annual global CO2 emissions, the iron and steel industry is expected to undertake the largest contribution to industrial decarbonisation. Despite the launch of several national and regional programmes for low-carbon steelmaking, the techno-economically feasible options are still lacking. Here, based on the carbon capture and storage (CCS) strategy, we propose a new decarbonisation concept which exploits the inherent potential of the iron and steel industry through calcium-looping lime production. We find that this concept allows steel mills to reach the 2050 decarbonisation target by 2030. Moreover, only this concept is revealed to exhibit a CO2 avoidance cost (12.5–15.8 €2010/t) lower than the projected CO2 trading price in 2020, whilst the other considered options are not expected to be economically feasible until 2030. We conclude that the proposed concept is the best available option for decarbonisation of this industrial sector in the mid- to long-term.

“…With a charcoal price of 400 €/t and pulverized coal price of 150 €/t, the CO 2 allowance price should be almost 50 €/t CO 2 to reach the break-even point. Comparing biomass use to other CO 2 emission mitigation strategies used in the steel industry, such as Carbon Capture and Storage (CCS), one can see that high emission allowance prices are needed in that option too, break-even prices reaching a level of 72 €/t CO 2 in the most favorable option with current solvent technology [60]. The costs for avoided emissions with CCS are sensitive to several factors, e.g., electricity price, used solvents, captured CO 2 amount and selected system boundaries [60].…”

Replacement of fossil carbon by renewable biomass-based carbon is an effective measure to mitigate CO 2 emission intensity in the blast furnace ironmaking process. Depending on the substitution rate of fossil fuels, the required amount of biomass can be substantial. This raises questions about the availability of biomass for multiple uses. At the same time, the economic competitiveness of biomass-based fuels in ironmaking applications should also be a key consideration. In this assessment, availability of energy wood, i.e., logging residues, small-diameter wood and stumps, in Finland is discussed. Since biomass must be submitted to a thermochemical process before use in a blast furnace, the paper describes the production chain, from biomass to charcoal, and economics related to each processing step. The economics of biomass-based reducing agents is compared to fossil-based ones by taking into account the effect of European Union Emissions Trading System (EU ETS). The assessment reveals that there would be sufficient amounts of energy wood available for current users as well as for ironmaking. At present, the economics of biomass-based reducing agents in ironmaking applications is unfavorable. High CO 2 emission allowance prices would be required to make such a scheme competitive against fossil-based reducing agents at current fuel prices.

“…In post‐combustion techniques, CO 2 is separated from flue gases without altering the traditional combustion procedure. In this process, fossil fuels are combusted in excess air, and the product stream contains CO 2 concentration of 12–15% in coal fired combustion, 4–11% for natural gas, and 25–33% in blast furnaces . The capture technique offers flexibility in operation in such a way that, if the capture plant shuts down, the power plant can still operate.…”

Post‐combustion CO₂ capture with chemical absorption and hybrid system: current status and challenges

et al. 2018

Post-combustion CO 2 capture from the power and industrial sectors has gained widespread attention due to its ability to retrofit easily with newly installed and existing plants. This state-of-the-art, updated review provides an overview of technical issues in post-combustion CO 2 capture related to process performance, energy requirements for CO 2 capture, and inconsistencies in the prediction of CO 2 capture cost. Recent updates are presented regarding chemical absorption-desorption systems, and particularly CO 2 absorption and solubility enhancement studies, absorber operation at elevated pressure, recent developments in absorber configuration, and methods for reducing the heat duty of strippers. Furthermore, recently developed post-combustion hybrid techniques such as the membrane-absorbent hybrid process, the membrane-cryogenic hybrid process, the membrane-adsorption hybrid process, the absorption-electrolysis hybrid process, and the solar thermal electrochemical process (STEP) are discussed. Finally, we suggest areas for improvement and indicate that there are significant future prospects for post-combustion CO 2 capture. C
