中文摘要: 为实现“双碳”目标,解决氢能大规模储存难题,结合中国氢能发展趋势,提出了包含盐穴储氢库的3种发展情景下的氢能“制–储–用”一体化方案:情景1,盐穴储存绿氢,用以燃料电池及炼钢炼铁领域;情景2,盐穴储存绿氢及CO2–O2混合气体,用于地面合成甲烷及甲烷富氧燃烧发电;情景3,盐穴储存合成甲烷,用以除发电以外的其他用途。从盐穴储氢库全生命周期的角度,分析了储氢库在3种发展情景下的作用,提出了多功能储氢库的概念:可起到废电利用、电力平衡、氢能安全高效储存、CO2减排等多项作用。以昆明市安宁盐矿及云南省为例,结合云南省水电为主的电力结构,分析了多功能盐穴储氢库在情景1、2中的建设需求:情景1,采用绿氢直接炼钢工艺,需电解绿氢约6.0×105 t,配套多功能盐穴储氢库总气量1.3×108 m3,可实现昆钢减排722 t;情景2,针对云南未来电力季节性缺额问题,假设甲烷富氧发电厂提供半年枯期电力,装机200 MW,仅需建设多功能盐穴储氢库总库容4.78×106 m3,可消纳水电5.34×108 kW·h,提供枯期发电量2.88×108 kW·h。

Abstract:In order to achieve the goals of carbon neutrality and emission peak and to solve the problem of large-scale storage of hydrogen, combined with the trends of hydrogen development in China, a “production-storage-use” integrated hydrogen chain was proposed. Scenario one is the current phase of hydrogen development, during which the salt cavern hydrogen storage is mainly for transportation and industry fields. In scenario two, salt cavern hydrogen storage and CO2–O2 mixed gas respectively, while the hydrogen is used for ground synthesis of methane as well as methane-enriched combustion for power generation. In scenario three, salt cavern stores synthetic methane for other purposes besides power generation. From the perspective of the full life cycle of salt cavern hydrogen storage, the role of salt cavern hydrogen storage under three scenarios was analyzed, and a new concept of multifunctional hydrogen storage was proposed. The multifunction of salt cavern is waste electricity utilization, power balance, safe storage of hydrogen and CO2 emission reduction. Taking Anning salt mine and Yunnan Province as examples, the potential of multifunctional salt cavern hydrogen storage was analyzed. In scenario one, for steelmaking, which needs 1.3×108 m3 of total gas volume storing 6.0×105 t of green hydrogen and reducing CO2 emission of 722 t. In scenario two, in view of the seasonal power shortage in the future of Yunnan, installing a capacity of 200 MW methane-enriched power plant providing a half-year power generation plant just needs 4.78×106 m3 of multifunctional salt caverns, which can absorb 5.34×108 kW·h of hydropower and provide 2.88 ×108 kW·h of power generation in dry season.
