報告摘要：Hydrogen is rapidly emerging as a pivotal energy carrier in the transition toward a net-zero future. Depleted gas reservoirs can store hydrogen at scale, yet pose complex challenges related to geo-mechanical stability, geochemical reactivity, and microbial activity. We discuss hydrogen–rock–brine chemistry, cap-rock sealing and cyclic injection-withdrawal performance, present reactive transport and geo-chemical modelling and international pilots, and outline pathways to safely integrate underground hydrogen storage within the broader renewable energy framework, ensuring supply stability and enabling large-scale decarbonisation of industrial and transport sectors.
