Core Insights - The industrial sector is responsible for 68% to 69% of China's total carbon dioxide emissions, making it crucial for achieving carbon neutrality goals [2] - The direct emissions from the industrial sector account for approximately 62%, while indirect emissions from purchased heat and electricity make up 38% [2] - Industrial heating contributes to about 50% of the total national emissions, highlighting the urgent need for low-carbon transformation in industrial heating systems [2] Group 1: Industrial Emissions Overview - In 2022, carbon emissions from obtaining heat and electricity reached 6.62 billion tons, accounting for 83% of total industrial emissions, with direct combustion contributing 4.97 billion tons [2] - If the low-carbon transformation of regional heating systems is achieved, it is estimated that carbon emissions in the Yangtze River Delta could be reduced by approximately 12 million tons per year by 2030 [3] Group 2: Technological Pathways for Transformation - Current coal-fired boiler heating has a carbon emission intensity 1.6 to 1.8 times higher than that of combined heat and power (CHP) systems, while gas boilers are slightly lower than coal CHP [4] - Low-temperature industrial heat pumps currently outperform coal CHP under existing electricity carbon intensity, and high-temperature heat pumps will show better emission reduction benefits as the proportion of green electricity increases [4] Group 3: Strategies for Achieving Zero Carbon Goals - To achieve comprehensive zero-carbon goals in industrial heating, multiple technological pathways must be pursued simultaneously, including increasing the proportion of electricity in terminal energy consumption from 28%-29% to over 50% [5] - The total scale of industrial boilers in China is 3.52 billion kilowatts, equivalent to the total installed capacity of the national power grid, indicating a need for a gradual transition strategy [5] - The dual approach of increasing the proportion of green electricity and developing green fuel alternatives is essential for achieving zero-carbon targets in industrial heating systems [5][6]
