Scenario Analysis of the Industrial Chain for Achieving Carbon Neutrality in China's Energy Industry

Based on the mature energy technologies, a industrial chain for achieving carbon neutrality in energy industry was presented by complementary integration of new energy generation, electrolytic water hydrogen production, biomass oxygen-enriched combustion, methanol synthesis, methanol reforming and other technologies. The chain can improve renewable energy consumption, achieve zero carbon emission of the whole process, realize long-distance storage and transportation of hydrogen, and reduce dependence on oil. A scenario prediction study was conducted for this industrial chain. From the perspectives of carbon neutral methanol production, oil substitution, carbon emission reduction, carbon neutral methanol production cost, comparative analysis was conducted by setting three influencing factors, such as scale of energy production, energy utilization rate of hydrogen production by electrolytic water, energy utilization rate of methanol synthesis by hydrogen.
