“…This process as other pH swing processes is also able to separate three different products: silica, magnesite and iron oxide. 56,66,68,106,114 This process could also be integrated with the chilled ammonia CO 2 capture process, which has been demonstrated to capture more than 90% of CO 2 (from 3-15% CO 2 in flue gas) 115 and an estimated energy penalty of 477 kW h per tCO 2 . 116 The main drawback of the aqueous pH swing ammoniumbased process is represented by the large amount of water that needs to be separated from the salts during the regeneration step.…”

Carbon dioxide (CO2) capture and sequestration includes a portfolio of technologies that can potentially sequester billions of tonnes of CO2 per year. Mineral carbonation (MC) is emerging as a potential CCS technology solution to sequester CO2 from smaller/medium emitters, where geological sequestration is not a viable option. In MC processes, CO2 is chemically reacted with calcium- and/or magnesium-containing materials to form stable carbonates. This work investigates the current advancement in the proposed MC technologies and the role they can play in decreasing the overall cost of this CO2 sequestration route. In situ mineral carbonation is a very promising option in terms of resources available and enhanced security, but the technology is still in its infancy and transport and storage costs are still higher than geological storage in sedimentary basins ($17 instead of $8 per tCO2). Ex situ mineral carbonation has been demonstrated on pilot and demonstration scales. However, its application is currently limited by its high costs, which range from $50 to $300 per tCO2 sequestered. Energy use, the reaction rate and material handling are the key factors hindering the success of this technology. The value of the products seems central to render MC economically viable in the same way as conventional CCS seems profitable only when combined with EOR. Large scale projects such as the Skyonic process can help in reducing the knowledge gaps on MC fundamentals and provide accurate costing and data on processes integration and comparison. The literature to date indicates that in the coming decades MC can play an important role in decarbonising the power and industrial sector.

We present a catalogue of galaxy groups and clusters selected using a friends‐of‐friends (FoF) algorithm with a dynamic linking length from the 2dF‐SDSS LRG and QSO (2SLAQ) luminous red galaxy survey. The linking parameters for the code are chosen through an analysis of simulated 2SLAQ haloes. The resulting catalogue includes 313 clusters containing 1152 galaxies. The galaxy groups and clusters have an average velocity dispersion of km s−1 and an average size of Mpc h−1. Galaxies from regions of 1 deg2 and centred on the galaxy clusters were downloaded from the Sloan Digital Sky Survey Data Release 6. Investigating the photometric redshifts and cluster red sequence of these galaxies shows that the galaxy clusters detected with the FoF algorithm are reliable out to z∼ 0.6. We estimate masses for the clusters using their velocity dispersions. These mass estimates are shown to be consistent with 2SLAQ mock halo masses. Further analysis of the simulation haloes shows that clipping out low‐richness groups with large radii improves the purity of catalogue from 52 to 88 per cent, while retaining a completeness of 94 per cent. Finally, we test the two‐point correlation function of our cluster catalogue. We find a best‐fitting power‐law model, ξ(r) = (r/r0)γ, with parameters r0= 24 ± 4 Mpc h−1 and γ=−2.1 ± 0.2, which are in agreement with other low‐redshift cluster samples and consistent with a Λ cold dark matter universe.
