A seminar by doctoral student Mursal Zeynalli on "Geological Storage of CO2" was held on May 15, 2026, organized by the Graduate School of Science, Art and Technology and the Department of Petroleum Engineering at Khazar University.

The presenter is pursuing doctoral studies in "Oil and Gas Engineering" at Khalifa University of the United Arab Emirates under a trilateral agreement with the Ministry of Science and Education of the Republic of Azerbaijan and Khazar University, within the framework of the "State Program on Increasing the International Competitiveness of the Higher Education System of the Republic of Azerbaijan for 2019–2023."

The seminar highlighted that geological storage of CO₂ represents one of the key solutions for reducing greenhouse gas emissions and achieving net-zero emission targets. The presentation provided a detailed analysis of the main stages of carbon capture and storage technology — including the capture, transportation, and injection of CO₂ into suitable underground geological formations such as depleted oil and gas fields or deep saline aquifers. The phase behavior of CO₂ was also explained, with emphasis on the fact that CO₂ in a supercritical state is more efficient for underground storage. Overall, it was noted that the long-term and safe storage of CO₂ depends on the integrity of the geological environment, reservoir conditions, and accurate assessment of storage mechanisms.
