Summary: This study constructed dynamic simulation models to investigate the injection of CO2 into saline aquifers in the Choszczno-Suliszewo structure in northwest Poland. The study analyzed two scenarios with different injection rates and observed changes in pressures and the spatial distribution of CO2 in the structure. The results showed that the sequestration process was highly effective due to the dissolution of CO2 in brine and resulting convection motion. Additionally, the displacement of injected CO2 to the sealing layers was observed.

Summary: This study investigated the variations in pore-network, mechanical, and hydrological characteristics of two different sandstone specimens subjected to CO2-enriched brine injection. The results showed significant permeability enhancement, increased porosity, enhanced pore connectivity, and increased surface gas permeability during CO2-enriched brine injection. Additionally, changes in mechanical characteristics of the specimens were observed, with mineral dissolution causing mechanical weakening in both specimens. Conducting further experiments on sandstones with different mineralogies is necessary to confirm the repeatability and statistical significance of the obtained results.

Summary: Rock wettability plays a crucial role in the fate of injected CO2, affecting trapping capacity and containment security. Field-scale numerical simulations reveal that wettability and injection rate strongly influence CO2 migration and storage efficiency. Water-wet sandstone exhibits 42% higher residual trapping compared to CO2-wet sandstone, and longer injection durations decrease residual trapping while increasing solubility trapping.

Summary: Supersonic decarburization, a clean CCUS technology using non-equilibrium condensation and swirling separation, is investigated through numerical simulation. The results show that higher pressure, inlet temperature, and mole fraction of CO2 facilitate the condensation process. For separation performance, increasing the mass concentration of inlet heterogeneous droplets improves carbon separation and reduces exergy loss of condensed CO2. This concept has potential applications in offshore natural gas processing for carbon capture.

Summary: Waste-to-Energy (WtE) is an important sector for carbon capture utilization and storage (CCS) due to its role in urban waste management and its potential for achieving negative emissions. This study investigates the integration of monoethanolamine (MEA) based Post-combustion CO2 Capture (PCC) in three representative WtE plant steam cycle configurations. The results show that heat recovery from the PCC process can be used for District Heating (DH), leading to a higher energy utility factor (EUF) for WtE plant with PCC compared to WtE plant without PCC. Furthermore, the study highlights the importance of differentiating carbon intensities for different product bases when comparing WtE CCS with other carbon saving technologies. The findings of this study provide valuable information for implementing carbon dioxide capture technology in the WtE sector.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.

Summary: Economic costs are a major political obstacle to investing in climate change mitigation and adaptation measures. The method of financing plays a crucial role in determining public opposition to government green investments, with debt financing being less opposed than broad-based taxes. This study suggests that credit market tools, such as green bonds and debt for climate swaps, can be politically efficient in increasing support for green financing. Carbon taxes and wealth taxes are found to be the most preferred options.

Summary: This paper investigates China's energy trade stability using a survival analysis approach. It finds that the energy trade linkages between China and 153 other countries are complex and unstable, with short periods of trade with many countries. Geopolitically risky regions, such as the Middle East and Africa, have the lowest trade stability. Climate risks have significant effects on energy trade stability. The paper proposes several policy options to improve energy trade stability in China, with special attention to increasing global climate risks.
