Core Viewpoint - The CCUS (Carbon Capture, Utilization, and Storage) technology is crucial for addressing climate change and reducing CO2 emissions, but its industrialization faces significant challenges, particularly funding issues [1][5]. Group 1: CCUS Technology and Applications - CCUS technology is essential for high-emission industries like steel and cement, where traditional methods cannot eliminate CO2 emissions effectively [3]. - Tencent's "Carbon Seeking Program" aims to foster low-carbon technology innovation, with the second phase receiving 660 applications from 54 countries, indicating growing interest in CCUS projects [2]. - Innovative projects include the use of local materials for carbon capture, conversion of captured CO2 into methane for steel production, and the development of sustainable industrial carbon materials [1][2]. Group 2: Challenges in Industrialization - Funding remains the most significant bottleneck for CCUS projects, as many laboratory technologies struggle to secure financial backing for industrial validation [1][5]. - Uncertainties in policy and carbon credit recognition hinder the development of CCUS, making it difficult for companies to realize the economic benefits of their low-carbon products [5][6]. Group 3: Recommendations for Industry Growth - The industry suggests establishing clearer carbon credit certification standards and aligning methodologies with international frameworks to enhance the credibility of CCUS projects [6]. - There is a call for increased public and private funding in energy-saving and carbon-reduction initiatives, along with incentives for low-carbon products to stimulate market demand [6].
