<p>With the increasingly severe problem of global climate change, the world steel industry, as one of the traditional high-carbon emission industries, faces great environmental pressure and emission reduction challenges. CCUS technology offers a solution to significantly reduce greenhouse gas emissions by capturing CO₂ produced in industrial processes and using it for underground storage or resource utilization. The application of CCUS technology in the world steel industry is still in its infancy, and some leading companies have begun to deploy related projects. However, high cost and technology maturity issues are the main obstacles to the scale application of CCUS technology. With technological progress, cost reduction, and the gradual establishment of a global carbon pricing mechanism, the application of CCUS technology in the steel industry is expected to be more widely promoted. This technology will play an important role in promoting the low-carbon transition of the steel industry and provide key support for achieving carbon neutrality goals. Policy support, funding, and synergies within and outside the industry will be key factors driving the development of CCUS technology.</p> Graphical Abstract <p></p>
