Comprehensive Review of Climate Change Mitigation through Cutting-edge LNG Technologies

This paper comprehensively reviews the potential of cutting-edge LNG technologies to mitigate climate change .We explore advancements in liquefaction processes, focusing on cryogenic heat exchangers, mixed refrigerant cycles, and turbo molecular expanders, aiming to improve efficiency and reduce energy consumption. Carbon capture and storage (CCS) technologies are examined as a strategy to capture and store CO2 emissions generated during LNG production. Novel approaches to methane emissions reduction, such as advanced leak detection and repair, membrane-based technologies, and utilization of boil-off gas, are also discussed. Liquefied natural gas (LNG) plays a significant role in the global energy landscape, but its life cycle raises concerns about greenhouse gas emissions, particularly methane leakage. Furthermore, the paper analyzes the efficient transportation and distribution of LNG, including LNG shipping technologies, cryogenic insulation, boil-off gas management, and supply chain optimization strategies for emissions reduction. Safe and responsible storage and handling practices are explored, encompassing onshore and offshore facilities, innovative storage solutions, and robust safety measures. The paper delves into the utilization of LNG in various end-use applications, including power generation, transportation (trucks, marine vessels), and industrial processes. While acknowledging the challenges of infrastructure development and cost considerations, the potential for emissions reduction across diverse sectors is highlighted. Finally, the paper emphasizes the importance of life cycle assessments to comprehensively evaluate the environmental impact of LNG. Collaborative efforts among industry stakeholders, governments, and research institutions are identified as crucial for accelerating the transition to cleaner LNG technologies. Continued research on leak mitigation, carbon capture, and life cycle optimization, alongside supportive policies and public awareness, are emphasized as essential for harnessing the potential of LNG for a sustainable future while mitigating climate change. This review provides valuable insights for policymakers, industry leaders, and researchers seeking to navigate the complex landscape of LNG and its role in a climate-conscious energy future.
