"双碳"目标下的我国二氧化碳高值利用机遇与挑战研究
The opportunities and challenges of China's high-value CO2 utilization under dual-carbon target
摘要
Abstract
High-value CO2 utilization technologies are emerging low-carbon energy technologies,which constitute an important part of China's carbon neutrality technology system.Since they are still in the early stage of development,they face systematic challenges such as high technological progress uncertainties,low market acceptance,and high economic costs.This study reviews the opportunities and challenges of high-value CO2 utilization technologies from the perspectives of technological,eco-nomic,and industrial landscape.Results indicate that:(ⅰ)From a macro-level perspective,the rising demand of high-value CO2 utilization may surpass the growing trend of existing supply capacity.Methane and methanol are the main products of high-value CO2 utilization technologies.Over the past 15 years,China's end-use demand for natural gas and methanol has increased 13-fold and fourfold,respectively.(ⅱ)From technology perspective,four mature technology paths include CO2 hydrogenation to methanol,thermo-catalytic production of methane,biomass-to-methane,and biogenic methane synthesis.Green methanol production pathways depend on a reliable supply of renewable electricity and coordinated electricity-hydrogen integration.Their costs remain substantially higher than those of conventional methanol production,and achieving economic and technical feasi-bility will require the large-scale deployment of low-cost green hydrogen within the energy system.(ⅲ)From the perspective of resources potential,only 30%of the provinces have both high-level potential for biomass and CO2.Considering the potential of biomass and CO2 from the perspective of the spatial heterogeneity is essential during the regional planning of coordinated high-value CO2 utilization development policies.(ⅳ)From the perspective of future challenges,the economic accounting system,data monitoring system,and engineering construction system face the non-negligible challenges.Specifically,they face the lack of full-chain economic assessments and multidimensional evaluation frameworks,difficulties in monitoring primary data,and high engineering complexity,respectively.The study puts forward three policy suggestions.Firstly,the government should put emphasis on the national macro-level mechanism design and multi-level policy support for the high-value CO2 utilization industry,while providing targeted assistance for relevant technologies based on their technological maturity,regional differences,and the characteristics of green chemical production.Secondly,the construction of a cross-disciplinary education system and breakthroughs in core technologies should be accelerated,while recognizing the role of small and medium-sized enterprises and improving the quality of university-industry collaboration.Thirdly,developing a scientifically grounded,long-term,phased development roadmap and conduct dynamic,forward-looking assessments for advanced technologies.This study provides implications for other early-stage technologies to overcome the bottlenecks through technological,economic and industrial innovation efforts.关键词
