"The scale of global carbon capture, utilization and storage (CCUS) technology is gradually increasing, from 26 million tons to 55 million tons between 2013 and 2023. The proportion of developed countries has declined, and developing countries have grown significantly, becoming a key technology to address climate change."
When the earth’s breathing gradually becomes heavier, human wisdom is like stars, twinkling in the endless universe, and the movement of carbon capture, utilization and storage (CCUS) is quietly playing. It is not only a symphony of technology, but also an affectionate confession to Mother Earth. Carbon Capture Utilization and Storage (CCUS), like a thin thread, is trying to closely connect the progress of human civilization with the dream of environmental protection. During this long journey, it is not only a key to mitigating climate change, but also a mysterious spell that opens the door to future sustainable development. Carbon capture is the beginning of this drama. Like a delicate craftsman, it captures the free carbon dioxide molecules from the smoke emitted by industry and "salvages" them from the atmosphere. The capture of every molecule is a gentle commitment to the earth. Carbon utilization is the climax of this scene. These captured carbon dioxide are no longer an environmental burden, but a magical material that turns waste into treasure. They are transformed into building materials, plastics, and even fuel, breathing new life into industrial production while also easing the burden on nature. This process, like a magician's spell, transforms waste into treasure. Carbon sequestration is the final chapter of this journey and the beginning of a new chapter. The captured carbon dioxide is safely sent deep underground, or converted into renewable resources and stored in rocks, waiting for the test of time. This is not only a victory of technology, but also a profound practice of the concept of harmonious coexistence between human beings and nature.

Carbon capture, utilization and storage is a global green revolution that crosses national boundaries and connects people of different cultures and beliefs. In this revolution, everyone is a participant and every country is an actor on the stage. From the forests of Northern Europe to the factories of Asia, from the grasslands of Africa to the farmlands of the Americas, carbon capture, utilization and storage is like a clear stream, nourishing the dry land and nourishing the common dreams of mankind. However, this revolution is not without challenges. It requires huge investment, innovative technology, and global cooperation. Just as a grand picture requires the interweaving of countless lines, the realization of global carbon capture, utilization and storage also requires the efforts and collaboration of every country. But just like the countless difficulties we have overcome together, as long as there is love in our hearts and a road under our feet, the future will be full of hope. Carbon capture utilization and storage technology is considered necessary due to existing greenhouse gas emissions in the atmosphere and difficult-to-electrify industries such as air travel. The primary carbon capture utilization and storage technology is post-combustion capture, used primarily by power plants to separate carbon from exhaust gases. Pre-combustion capture refers to the removal of carbon dioxide from fossil fuels before combustion is complete.
During the period from 2013 to 2023, the global carbon dioxide capture, utilization and storage volume quietly increased from 26 million tons to 55 million tons, achieving a growth of 111.53%. Although the scale is small, it outlines an increasingly steep growth curve, indicating that the potential of technology and the goal of addressing climate change are accelerating at an unprecedented speed. During this period, the amount of carbon dioxide captured, utilized and stored in developed countries climbed from 22 million tons to 33 million tons, a 50.00% jump. Although the proportion of carbon dioxide captured, utilized and stored in the global amount was has been reduced, but still occupies a pivotal position, sliding gracefully from 84.62% to 60.00%. Although it has dropped by 24.62 percentage points, it further demonstrates its unique value and unremitting efforts in addressing climate change. At the same time, developing countries have made remarkable achievements in the capture, utilization and storage of carbon dioxide, jumping from 04 million tons to 22 million tons, achieving an eye-catching 450% growth, significantly faster than developed countries; their proportion of global carbon dioxide capture, utilization and storage has also achieved an extraordinary leap, jumping from 15.538 to 40.00%, an increase of 24.62 percentage points, like adding a bright color to the blue skyline.
