Summary: Integrated techno-economic modelling suggests that the use of CO2 mineralisation in the cement industry can be profitable and reduce CO2-equivalent emissions by up to a third. This method requires the resulting products to be used in construction and meet the eligibility for emission certificates. The transport of minerals and the composition of the products are also crucial factors.

Summary: Carbon capture and storage (CCS) is an essential technology in reducing CO2 emissions from power and industry sectors. However, the deployment of CCS is lagging due to its perceived high cost. This paper investigates the impact of implementing CCS in industrial facilities on the overall costs and CO2 emissions of end-user products and services. The study shows that while CCS increases cement and steel costs, the overall construction cost of a bridge only slightly rises by 1%, but enables a significant reduction in CO2 emissions by 51%.

Summary: To accelerate the low-carbon transformation of the power industry, this paper examines the synergistic effect of stepped carbon emissions trading (CET) mechanism, energy storage system (ES), and carbon capture and storage (CCS) mechanism in a hybrid renewable energy system. The results show that the stepped CET increases renewable energy consumption by 0.12% and reduces carbon emissions by 0.6% compared to traditional CET. Additionally, the introduction of stepped CET and ES equipment together consumes 36.1% more renewable energy and reduces carbon emissions by 32.4%. Furthermore, based on the stepped CET model and ES equipment, the introduction of CCS system reduces carbon emissions by 29.4%.

Summary: With climate warming becoming increasingly severe, reducing carbon emissions has become a global consensus. However, the process of carbon emission reduction entails changes in economic, industrial, and energy structures, thereby affecting economic output, employment, and overall social welfare and equity. Therefore, it is crucial for every nation to determine a scientifically and effectively carbon emission pathway that considers both social development and climate targets. As the largest carbon emitter, China has set carbon peak and carbon neutrality targets. This paper designs corresponding carbon emission reduction scenarios based on China's new emission reduction situation. Additionally, an optimization model integrating economic growth, equity, and environment is developed to determine China's emission pathways from 2020 to 2050 while maximizing social welfare. The results quantitatively demonstrate future total amounts and peak values of carbon emissions under different scenarios, as well as their evolution over time. In most scenarios, the peak concentration will occur between 2025 and 2030, reaching approximately 10.7 to 11.8 billion tons. As carbon emission reduction constraints become more stringent, the cost of reduction will increase, although overall social welfare will slightly increase. Finally, the findings of this study provide practical guidance for achieving carbon emission reduction and offer insights for policymaking.

Summary: The study found that the total resistance curve in deep water shows a continuous increase with the Froude number, while in shallow water, a hump is witnessed near the critical speed. This difference is mainly caused by the pressure component of total resistance, which is significantly affected by the interaction between the wave systems created by the demihulls.

Summary: An automated practical multi-objective optimization scheme is proposed for ship hull modification. The scheme includes a shift transformation and a self-blending method based on resistance objectives at multi-design speeds. The Lackenby variation alters hull forms and produces initial designs, while the self-blending method combines obtained ships to cover the design space. The developed in-house optimization code provides an optimal and cost-effective solution for hydrodynamic optimization in the preliminary stage of ship design.

Summary: This study investigates the double-average turbulence characteristics of combined wave-current flow over a rough bed with different spacing arrangements. The results show that a spacing ratio of p/r=4 offers the highest resistance to the flow, and the double-average Reynolds stress decreases throughout the flow depth. The advection of momentum-flux of normal stress shows an increase at the outer layer and a decrease near the bed region after wave imposition. Maximum turbulence kinetic energy production and diffusion occur at different layers. The turbulence structure is strongly anisotropic at the bottom region and near the outer layer, with a decrease in anisotropy observed with an increase in roughness spacing.

Summary: The deep-water bridge is more vulnerable to earthquake damage than the bridge standing in air. The larger blocking ratio has a significant impact on the added mass coefficient, which requires further comprehensive study. The generation mechanism of block effect is analyzed using numerical simulation software ANSYS Fluent. The results show that the recirculation zone with focus reduces the pressure on the back surface of the cylinder, resulting in the peak value of in-line force not occurring synchronously with the peak value of acceleration. The change in position and intensity of the recirculation zone with focus, as well as the change in water flow around the cylinder surface, are identified as the generation mechanism of the block effect, which has a 10% influence on the hydrodynamic force. The changing rule of the added mass coefficient with blocking ratio is discussed in detail, and a modification approach to the current added mass coefficient calculation method is suggested. Physical experiments are conducted to validate the modification approach, and the results show that it is accurate and can be used in further study and real practice.
