“…10% of total cement production is 136kt), it shows that revenues of ETS certificates alone do not cover the costs of the mineralisation. The here calculated values for cost and carbon footprint reductions are consistent with previous studies, when taking into account that a blend of inert and silica is used to produce SCMCCU 19,27 .…”

“…3. Previous work on CO2 mineralisation has shown that CO2 storage cost when using virgin minerals as feedstocks could be in the range of 65-443€/tCO2 avoided 26 (excluding CO2 capture) 27 (Supplementary Table 1). However, these studies neglect the value added from the sale of the resulting products, which may be critical to successful adoption by players in an industry characterised by strong competition and high pressure on price.…”

The cement industry is responsible for approximately 7% of anthropogenic CO2 emissions with low margins and the highest carbon intensity of any industry per unit of revenue. To encourage complete decarbonisation of the cement industry, strategies must be found in which GHG emission reductions are incentivised. Here we show through integrated techno-economic modelling that CO2 mineralisation using silicate minerals results in emission reductions of 6–31% while generating an additional profit of up to €28 per tonne cement. In order to create positive CO2 mineralisation business cases three conditions are paramount: the resulting products must be used as a supplementary material in cement blends, the storage of CO2 in minerals must be eligible for ETS credits or similar, and the feedstock minerals must be available in close proximity ( < ~ 550km, transported by truck and train).

“…Nowadays, the most advanced and mature carbon capture technique is solvent absorption [ 7 , 8 , 9 ], but more environmentally friendly approaches have also been studied, such as mineralization [ 10 ], cryogenic separation [ 11 ] and, as in this work, membrane separation [ 12 , 13 , 14 , 15 , 16 ].…”

Pebax® 2533/Graphene Oxide Nanocomposite Membranes for Carbon Capture

et al. 2020

In this work, the behavior of new GO-based mixed matrix membranes was tested in view of their use as CO2-selective membrane in post combustion carbon capture applications. In particular, the new materials were obtained by mixing of Pebax® 2533 copolymer with different types of graphene oxide (GO). Pebax® 2533 has indeed lower selectivity, but higher permeability than Pebax® 1657, which is more commonly used for membranes, and it could therefore benefit from the addition of GO, which is endowed with very high selectivity of CO2 with respect to nitrogen. The mixed matrix membranes were obtained by adding different amounts of GO, from 0.02 to 1% by weight, to the commercial block copolymers. Porous graphene oxide (PGO) and GO functionalized with polyetheramine (PEAGO) were also considered in composites produced with similar procedure, with a loading of 0.02%wt. The obtained films were then characterized by using SEM, DSC, XPS analysis and permeability experiments. In particular, permeation tests with pure CO2 and N2 at 35°C and 1 bar of upstream pressure were conducted for the different materials to evaluate their separation performance. It has been discovered that adding these GO-based nanofillers to Pebax® 2533 matrix does not improve the ideal selectivity of the material, but it allows to increase CO2 permeability when a low filler content, not higher than 0.02 wt%, is considered. Among the different types of GO, then, porous GO seems the most promising as it shows CO2 permeability in the order of 400 barrer (with an increase of about 10% with respect to the unloaded block copolymer), obtained without reducing the CO2/N2 selectivity of the materials, which remained in the order of 25.

“…As highlighted by Naraharisetti et al, [ 52 ] detailed economic evaluation of the process of CO 2 mineralization is limited. Pasquier et al [ 146 ] performed a techno‐economic evaluation on CO 2 mineralization using mining wastes and raw flue gas, concluding that while mineral carbonation costs are high compared with other forms of CO 2 storage, the integration of such a process in a niche market is feasible.…”

Carbon dioxide utilization is increasingly attracting interest. CO2 utilization involves a multitude of processes and chemical reactions. In this context, the goal of this review is to analyze the techno‐economic feasibility, sustainability, and social opportunities of CO2 utilization, as a possible contribution to CO2 mitigation in Europe. Industries and the most recent European projects related to carbon capture and utilization are also discussed, illustrating Europe's performance dynamics in science, research, and innovation in this field. The latest developments in CO2 utilization are thus reviewed, including chemicals, mineral carbonation, and biological uses. This study examines a few CO2‐based pathways at high level of maturity covering a wide range of applications, and discusses their current technical feasibility, economic viability, sustainability, and social aspects. They are then evaluated using several indicators to provide a figure of merit, where qualitative results are intended. The mapping and ranking of CO2 utilization pathways may provide a valuable means in prioritizing support and funding to facilitate the development of large‐scale CO2 utilization projects in Europe. Finally, key challenges and opportunities are discussed. The review shows that CO2 utilization may not be a complete solution for Europe, but will support climate change objectives, circular economy, and resource and energy security.
