Special Issue Information

Dear Colleagues,

Anthropogenic emissions of carbon dioxide (CO2) have made a visible impact on the global environment and climate since the industrial revolution. The steady buildup of CO2 as a major greenhouse gas in atmosphere is believed to be a major contributor to global warming. Guided by the Paris Agreement’s long-term goal to limit the global average temperature rise in the 21st century within 2 °C while making efforts to limit the rise even further to 1.5 °C, 192 countries and the European Union are taking active measures to substantially reduce carbon emissions and increase carbon sequestration. However, natural carbon sequestration in terrestrial ecosystems such as forests, grasslands, deserts, wetlands, and farmlands, as well as in oceans and karst regions, is far below to maintain a balance against the CO2 into atmosphere. In addition to shifting the energy structure to one with a major share of renewable energy, artificially enhanced carbon sequestration involving geological processes needs more attention in the course of realizing net-zero carbon emissions. Currently, studies of geological carbon sinks and geological CO2 sequestration remain challenging topics. Thus, in this Special Issue, we invite authors to submit original research and review articles relevant to geological carbon sinks and sequestration, including natural and artificial carbon sequestration processes, mechanisms, and potentials via physical, chemical, and biological interactions between the lithosphere, hydrosphere, atmosphere, and biosphere during geological processes, as well as strategies for and management of carbon neutrality. This issue will provide a geological insight that will be of use for our journey to carbon neutrality.

Topics of interest for publication in this Special Issue include but are not limited to:

  • Carbon cycling;
  • Karst carbon sink;
  • Soil carbon sink;
  • Wetland and swamp carbon sink;
  • Mineralized carbon sinks of basic–ultrabasic rocks;
  • Conventional and unconventional geological carbon sequestration;
  • Geological energy storage;
  • Policies, legislation, and management with regard to carbon neutrality.

Through extensive data research and analysis, this paper comprehensively summarizes the status and key insights of global carbon dioxide capture and storage (CCS) development. It aims to gain a comprehensive understanding of the relevant policies, technologies, and security measures adopted by major countries in their CCS development processes. Furthermore, it explores the existing status and limitations of China’s offshore development efforts, while providing valuable recommendations for enhancing China’s offshore CCS initiatives, as well as serving as a reference for other nations worldwide. Offshore CCS plays a crucial role for China to achieve the development target of carbon peak and carbon neutrality, due to its energy structure and industrial distribution. While China possesses significant offshore CCS potential, achieving commercialization still requires substantial efforts. To facilitate the process and draw insights from successful experiences in other countries, this paper illustrates the characteristics and generalizes the experience of offshore CCS industry practices in America, Europe and Japan, respectively. Furthermore, it is recommended that a new round of investigation into offshore CCS potential be conducted, while promoting integrated collaboration between geological surveying and marine scientific research. Additionally, further research on industrial policies and green financial strategies should be undertaken. Full article

The geological storage of carbon dioxide (CO2) is the most suitable option to achieve a large-scale and low-cost CO2 emissions worldwide, but the selection of favorable areas for the geological storage is the main issue. In this study, evaluation indicators were selected considering four aspects, namely geological conditions, storage potential, hydrogeological conditions, and engineering conditions, based on drilling, geophysical, and geochemical data from the Beibu Gulf Basin. The analytical hierarchy process and the fuzzy comprehensive evaluation method were used to evaluate the suitability of this basin for geological storage of CO2. The results suggested that: (1) the Beibu Gulf Basin is suitable for CO2 geological storage, and the evaluation grade is the highest rating level; (2) considering the techno-economic feasibility, it is necessary to select the target area for CO2 geological storage with suitable burial depth, superior reservoir conditions, proximity to the CO2 collection device, and a high degree of exploration.

Carbon dioxide (CO2) storage in underwater reservoirs is a valuable method of reducing carbon emissions. Saline aquifers such as those in the South Yellow Sea Basin (SYSB), China, have great potential for geological CO2 storage. Thus, we use the recommended calculation method of USDOE and a formation volume model to determine the geological conditions for CO2 storage and estimate the CO2 storage capacity of the Cenozoic saline aquifers in the SYSB (depth: 800–3200 m). Overall, the SYSB exhibits weak fault activity and seismicity, medium and low geothermal fields, four types of source sandstone reservoir, and four sets of carbon reservoir–caprock assemblages developed from the Cenozoic strata, providing relatively good geological conditions for CO2 storage. The estimated capacity of the Cenozoic strata ranges from 39.59 Gt to 426.94 Gt (average: 155.25 Gt), indicating an extensive storage capacity that can meet the carbon sequestration needs of Shandong and Jiangsu Provinces for approximately 89 years. The Yantai Depression has a lower geothermal gradient and terrestrial heat, weaker seismic activity, and double the storage capacity of the Qingdao Depression, indicating that it is the most suitable area for Cenozoic CO2 storage in the SYSB, whereas the Laoshan Uplift is not suitable for storage. This study provides a scientific basis for the selection of offshore CO2 storage sites. Full article
