摘要
中国为了2060年能够实现碳中和目标,必须依靠中国能源供需结构的深刻转变,从高碳向低碳、无碳能源转型。未来中国天然气消费将迎来大规模的消费增长,预计到2030年中国天然气消费量约为6000×10^(8) m^(3),2060年天然气消费量预计达到6500×10^(8)~7500×10^(8) m^(3)。中国天然气受自身资源、获取国际资源能力、进口通道安全等多种因素的影响,必须建设大规模地下储气库以满足中国天然气消费增长需求。从天然气消费安全角度,中国需建设储气能力达1200×10^(8)~1300×10^(8) m^(3)的地下储气库,既满足中国天然气调峰需要,又有一定的战略储备。中国目前地下储气库工作气量仅约150×10^(8) m^(3),必须进一步扩大建库领域,形成“1+3+N”的储气库基地空间布局。在中国能源转型过程中,储气库相关技术可与未来碳埋存、储氢、储氦、压气蓄能等技术深度融合,最大限度地发挥地下储气库在能源领域的作用,确保碳中和战略目标的实现。(图2,表4,参24)
For China to achieve carbon neutrality by 2060,the profound transformation from high-carbon to low-carbon and carbon-free energy sources is required for the energy supply and demand structure.In the future,the gas consumption will grow in large scale in China.It is estimated that the natural gas consumption in China will be about 6000×10^(8) m^(3) by 2030 and 6500×10^(8) m^(3) to 7500×10^(8) m^(3) by 2060.Due to the impact of the resource reserves,the capability to acquiring international resources,the safety of import channels and other factors on China’s natural gas,it is necessary to build underground gas storages in large scale to ensure the growth of China’s natural gas consumption.From the perspective of natural gas consumption safety,the underground gas storages with a gas storage capacity of 1200×10^(8) m^(3) to 1300×10^(8) m^(3) should be constructed,so as to meet the requirements for peak sheaving of natural gas in China and maintain the strategic reserves required.At present,the working gas capacity of China’s underground gas storages is only about 150×10^(8) m^(3),and it is necessary to further expand the field of storage construction to form the space layout of“1+3+N”gas storage base.In the process of China’s energy transition,the related technologies of gas storage will be deeply integrated with the carbon storage,hydrogen storage,helium storage,compressed gas storage and other technologies in the future,for the purpose of maximizing the role of underground gas storages in energy field and facilitating to realize the strategic objective of carbon neutrality.(2 Figures,4 Tables,24 References)
