“…Various measures exist for CO2 mitigation generally and utilisation specifically ( Fig. 1), including enhanced oil and gas recovery (EOR and EGR, the latter including coal-bed methane -ECBM), CO2 conversion to chemical feedstock and fuels, biological conversion (photosynthesis), and CO2 mineralisation for the production of materials (Laumb et al, 2013;Hasan et al, 2014). These methods are primarily focussed on CO2 utilisation following capture; only biological conversion is capable of direct CO2 mitigation.…”

Algal remediation of CO2 and nutrient discharges: A review

The recent literature pertaining to the application of algal photobioreactors (PBRs) to both carbon dioxide mitigation and nutrient abatement is reviewed and the reported data analysed. The review appraises the influence of key system parameters on performance with reference to (a) the absorption and biological fixation of CO2 from gaseous effluent streams, and (b) the removal of nutrients from wastewaters. Key parameters appraised individually with reference to CO2 removal comprise algal speciation, light intensity, mass transfer, gas and hydraulic residence time, pollutant (CO2 and nutrient) loading, biochemical and chemical stoichiometry (including pH), and temperature. Nutrient removal has been assessed with reference to hydraulic residence time and reactor configuration, along with C:nutrient ratios and other factors affecting carbon fixation, and outcomes compared with those reported for classical biological nutrient removal (BNR). Outcomes of the review indicate there has been a disproportionate increase in algal PBR research outputs over the past 5-8 years, with a significant number of studies based on small, bench-scale systems. The quantitative impacts of light intensity and loading on CO2 uptake are highly dependent on the algal species, and also affected by solution chemical conditions such as temperature and pH. Calculations based on available data for biomass growth rates indicate that a reactor CO2 residence time of around 4 h is required for significant CO2 removal. Nutrient removal data indicate residence times of 2-5 days are required for significant nutrient removal, compared with <12 h for a BNR plant. Moreover, the shallow depth of the simplest PBR configuration (the high rate algal pond, HRAP) means that its footprint is at least two orders of magnitude greater than a classical BNR plant. It is concluded that the combined carbon capture/nutrient removal process relies on optimisation of a number of process parameters acting synergistically, principally microalgal strain, C:N:P load and balance, CO2 and liquid residence time, light intensity and quality, temperature, and reactor configuration. This imposes a significant challenge to the overall process control which has yet to be fully addressed.

The rise of modern Portland cement has relegated lime to a secondary role in the construction industry, now mainly used for repairing and restoring historical buildings. This study proposes an innovative application of partially calcined limestone (PCL) as a carbonated material. The impact of varying MgO dosages on the carbonation mechanism of PCL is explored. It is found that a 5% MgO dosage significantly enhances the 1 d compressive strength postcarbonation by over 84.7%. The critical role of hydrated MgCO 3 , produced from MgO, in the formation and crystallinity of CaCO 3 is highlighted. However, it is observed that excessive MgO can impede carbonation, negatively impacting the mechanical properties and pore structure of the material. The presence of MgCO 3 •3H 2 O is noted to significantly influence the compressive strength of the carbonated material. Potential pathways for dolomite formation in PCL with different MgO dosages are suggested, indicating new possibilities for creating high-performance, low-carbon cementitious materials.

Although the conclusions are often contradictory, it is commonly suggested that there still exist large barriers for the implementation and deployment of CCU.…”

The economics of CO 2 utilization are discussed from a critical perspective, with a concise analysis of the state-of-the-art of economics in power-to-X (methanol, methane). The main elements of the analysis of the economics are commented to provide guidelines on how to interpret the techno-economic results in the area of CO 2 utilization. It remarks the need of a careful analysis of the specific context, and of the limits of the evaluation, in order to go beyond the just use of the results without a proper analysis of how the data support the conclusions, their limits and applicability. Case examples discussed in a more detail regard the CO 2 to methanol or methane conversion, from the perspective of highlighting possible issues or limits rather than to indicate which results are more valuable, which is out of the scope of this contribution.
