The zero-carbon industrial park (factory) solution centers on the integration of Source-Grid-Load-Storage, establishing a whole-industrial-chain energy conservation and carbon reduction system covering "green energy supply + industry/new energy coupling + digital-intelligent management and control". For zero-carbon industrial parks, characterized by concentrated carbon emissions, difficulty in carbon reduction via traditional technologies and abundant waste heat/pressure resources, key technologies will be developed including integrated PV-storage-charging technologies, deep coupling technologies between new energy and the chemical industry chain, comprehensive utilization technologies for waste heat and pressure, Zero Liquid Discharge (ZLD) technologies for industrial wastewater, CCUS and ecological carbon sink technologies, as well as a digital energy-carbon management platform, achieving full-process carbon reduction from source to process to terminal. For zero-carbon factories, marked by a single energy consumption structure and high product carbon emissions, emphasis will be laid on developing integrated PV-storage-charging technologies, ground-source/air-source heat pump heating and cooling technologies, product carbon footprint and digital energy-carbon management platforms, enabling green and low-carbon production of products.
