Abstract:

Based on the perspective of “source-process-end”, this study takes iron and steel, building materials, petrochemical and chemical industries as the entry point, reviews the status quo of industrial low-carbon technology development, proposes the innovation path of source zero-carbon technology, process carbon-reduction technology and end negative-carbon technology, and draws timetables and roadmaps for low-carbon technology innovation. Focusing on the transformation of energy structure at the source, this study proposes to build a multi-energy complementary system in stages. According to the characteristics of the industry, this study puts forward the phased promotion route of each industry. The phased scale application path of CCUS is also cleared. This paper hopes to provide direction guidance and technical reference for green and low-carbon development of industry in China.
