With the global attention to climate change and the national carbon neutrality, CCUS has received increasing attention as the key to achieve the carbon neutrality target. However, Due to poor economics, CCUS is difficult to commercialize in large scale. The carbon market is a relatively economical means to achieve emission reduction goals. Currently the carbon market is an important platform to achieve emission reduction goals and reduce the overall cost of social emission reduction. In the future, the development and growth of CCUS in China still need the assistance of the carbon market in mechanisms, methodologies, and standard processes.

As a major source of energy in the world today, the state of oil reserves has become an important indicator of a country’s strength. Many countries, including China, are actively increasing energy reserves to cope with increasingly severe geopolitical risks and international market risks. This article provides an introduction to the international energy landscape, highlighting the progress made in energy reserves both domestically and globally. It places particular emphasis on China’s underground oil (gas) storage technology, discussing its current status and future prospects. Furthermore, the article anticipates the advancements expected in oil storage, gas storage, hydrogen storage, and other related technologies.

In the background that countries all over the world have gradually reached the climate consensus and successively announce the goal of carbon neutrality, CCUS has been more prominently standing out with its necessity and importance to be an essential key technology to promote massive utilization of fossil fuels and reach sustainable development scenario, becoming flourished with a positive trend in recent years. Based on the analysis of the development status of CCUS, this paper focuses on the effective supporting policies and business models of both domestic and foreign banks, forms a judgment on the future trend of the industry, and puts forward relevant suggestions for the promotion of the CCUS industry.

In recent years, with the advancement of geothermal heating engineering technology, the projects and scale of geothermal heating have continued to grow. At present, geothermal development and utilization projects are mostly researched on economic evaluation methods, main control factors of benefits and case analysis of project benefits. Post-evaluation of economic benefits can provide strong support for improving existing projects, adjusting projects under construction, and guiding proposed projects, but there are few studies on post-evaluation of economic benefits of completed geothermal heating projects. In order to improve the economic benefits of geothermal heating projects and change extensive management to intensive management, this paper studies the post-evaluation principles, methods and evaluation indicators of the economic benefits of hydrothermal geothermal heating projects, and take the geothermal water heating project of S community in Xianyang City as an example to carry out the post-evaluation research on economic benefits. Through research, it is suggested to carry out post-economic evaluation of geothermal utilization projects that have been completed and run for 3 to 5 years. In order to do a good job in the post-evaluation of economic benefits, the evaluators should continue to track the progress of the project, collect and analyze various historical data in a timely manner, and select a variety of methods for prediction, comparison and mutual correction. In order to fully reflect the benefits of geothermal heating, the indirect benefit evaluation of energy conservation and emission reduction of geothermal heating projects will be strengthened in the future.

Since the 1960s, the global natural gas industry has developed rapidly, and natural gas has become a fossil fuel that can balance supply stability, economic efficiency of consumption, clean and low-carbon features at the current stage. However, there is a regional imbalance in the global demand for natural gas, and the continuous rise in geopolitical risks negatively affects the stability of the natural gas market. In recent years, LNG export capacity in the U.S. has continued to grow, and the potential for China-U.S. LNG trade in the future is enormous. From the perspective of development opportunities, strengthening LNG trade cooperation with the U.S. is conducive to the diversification of natural gas import sources for China. From the perspective of challenges, China-U.S. LNG trade cooperation also involves potential risks in terms of economy and channels.

2.The rapid development of the digital economy and profound changes in currency functions have driven the emergence of a large number of digital currencies. In order to improve the competitiveness and efficiency of payment systems, governments all over the world have accelerated the research and development of central bank digital currency (CBDC). After years of preparation and research and development, Digital renminbi has also entered the pilot application stage. Given the many shortcomings of the current cross-border payment system, CBDC cross-border payment has become an important development direction. At present, some central banks are collaborating on CBDC cross-border payment research and initiating experimental plans to explore CBDC cross-border payment arrangements. With the expansion of the acceptance range of Digital renminbi and the improvement of the international use level of CNY, oil and gas enterprises will have broad prospects in the cross-border payment field in the future. This paper suggests that oil and gas enterprises, in accordance with the principle of “from easy to difficult, step by step”, give priority to the introduction of Digital renminbi from regions and fields where RMB or local currency settlement has been achieved, and combine Digital renminbi with imported oil and gas to explore the use of Digital renminbi in cross-border payment.

As an important measure to deal with climate change, the implementation of the EU carbon border adjustment mechanism (CBAM) will inevitably have an impact on the export of some products in China, and even have a far-reaching impact on the global industrial chain layout. On the basis of expounding the basic content and construction purpose of EU’s carbon border adjustment mechanism, this paper reveals the influence of carbon border adjustment mechanism on China-EU trade by analyzing the current situation of China-EU trade, and points out that the impact of carbon border adjustment mechanism on China’s macro-economy in the short term is limited, but it will weaken the international competitiveness of China’s steel and aluminum industries to some extent and increase the export costs of related enterprises in China. Therefore, China should improve the carbon emission trading system and the domestic carbon trading market; Accelerate the promotion of industrial green and low-carbon competitiveness; Implement the carbon-neutral strategy of enterprises to promote the low-carbon transformation of enterprises; Timely negotiation and consultation with the EU to deepen international cooperation.

Since SINOPEC carried out the action plan of dramatically improving oil and gas exploration and development in 2019, oilfield development front has actively overcome the impact of disadvantage factors such as sharp fluctuations in oil prices, recurrent COVID-19 and withdrawal of nature reserves, fully implemented the decision and deployment of company group’s party leadership, focused on improving productivity, controlling decline, increasing recoverable capacity and reducing cost, adhered to the detailed reservoir understanding, precise plan deployment, detailed supporting processes and actuarial development benefits for strengthening the construction of production efficiency, paid close attention to the detailed development of old oilfields, enhanced the promotion and application of significantly improved oil recovery technology, put forth effort on consolidating the foundation of stable production, to make sure the production stable and rising, and oil production exceeded the planned target during the period from 2019 to 2022. In 2022, 35.32 million tons oil were produced, with an increase of 0.16 million tons, marking the largest increase in the nearly past four years.

Energy is an important cornerstone for the development of human society and is crucial for the development of a country's economy and society. In the past decades, European countries have been dependent on Russian gas imports to meet their energy needs. However, changes in the international energy geopolitical landscape and adjustments in Russia's energy policy, coupled with U.S. and Western sanctions against Russia and Russian counter-sanctions due to the Ukraine crisis, have further complicated the already severe energy supply and demand situation in Europe, leading to increased energy supply uncertainty and sharp increases in energy prices in several European countries, especially in natural gas energy. Energy uncertainty and risks have turned into a serious energy crisis. The European energy crisis not only has a direct impact on the economic and social development of European countries, but also greatly affects the global energy supply and demand pattern, global economic trade and industrial chain and supply chain security. A deep understanding of the causes of the European energy crisis and the strategies and measures taken by European countries to cope with the energy crisis has important implications for us to avoid energy risks.
