Summary: Geological CO2 storage is a promising approach to mitigate global carbon emissions, and saline aquifers and oil/gas reservoirs have been proven to be the most suitable storage sites. This paper proposes a novel strategy of enhancing CO2 storage capacity by synthesizing and utilizing high-dryness CO2 foam. Through experiments, it is confirmed that the new foam can effectively increase storage capacity and reduce water consumption.

Summary: The study investigates the feasibility of storing CO2 inside hydrate stability zone (HSZ) through reservoir pressure management via water producers and CO2 injectors. Results show that by controlling reservoir pressure, CO2 can be stored in HSZ with the formation of CO2 hydrate delaying CO2 breakthrough and limiting gas leakage. The research highlights the potential of storing CO2 in aquifers with a HSZ, with implications for CO2 geological storage.

Summary: A four-scale and three-level CO2 storage potential evaluation method for saline aquifers in a petroliferous basin in China is proposed, considering geological, engineering, and economic factors. The method evaluates theoretical storage capacity, engineering storage capacity, and economic storage capacity, considering factors such as trapping mechanisms, injectivity, storage security pressure, well number, and carbon pricing yield. Application of this method in the Gaoyou sag of the Subei Basin reveals the proportion of different trapping mechanisms and highlights the significant difference between theoretical, engineering, and economic storage capacity.

Summary: This study proposes a Pareto-based multi-objective optimization for operating CO2 sequestration with a multi-well system under geological uncertainty. The influence of geological uncertainty on CO2 sequestration is evaluated through a sensitivity analysis, showing the significant impact of spatial properties on trapping volume. Results discuss the effects of spatial heterogeneity on achieving CO2 geological storage and provide an operation strategy including multi-objective optimization.

Summary: The application of Saline Aquifer CO2 Storage (SACS) projects in offshore saline aquifers in China shows promising potential in terms of technical and economic viability. However, the storage capacities determined by different methods vary significantly. The CO2BLOCK method seems to provide more reasonable results and further confirms the immense potential of industrial-scale pilot and demonstration CO2 storage projects in offshore deep saline aquifers in China.

Summary: This paper numerically studied the geochemical reaction mechanism of CO2 storage in saline aquifers and its effects on the reservoir rocks and CO2 consumption. The results showed that the long-term geochemical reactions did not affect the porosity and permeability of the rocks and had no adverse consequences for extraction. The captured CO2 was distributed in gas, aqueous phase, and minerals, accounting for 27%, 65%, and 8% respectively. The study provides a theoretical reference for underground energy storage projects involving fluid-rock interactions.

Summary: CO2 marine geological sequestration is a crucial measure to reduce atmospheric CO2 levels and mitigate the harmful effects of global warming. Compared with traditional terrestrial geological sequestration, CO2 marine geological sequestration has greater potential, a safer distance from aquifers, and stable temperature and pressure conditions, making it safer and more efficient. This paper reviews and evaluates the main CO2 marine geological sequestration technologies and discusses their mechanisms, potential, challenges, and adverse effects on marine environments. The potential development trends in CO2 marine geological technology are also explored.

Summary: Carbon capture and sequestration (CCS) is the only viable method for reducing massive amounts of carbon dioxide (CO2) from the atmosphere. However, the process poses geomechanical risks, such as caprock failure and induced seismicity, which may lead to environmental concerns and hinder public acceptance. This paper provides an overview of these risks, reviews their mechanisms and theories, and introduces relevant precedent studies. The study aims to enhance understanding of geomechanical risks during CCS and facilitate the optimal design of the process for public acceptance. Challenges related to handling these risks are also discussed.
