English
This global review examines the nexus between the hydrogen economy and carbon capture, utilization, and storage (CCUS) technologies. It analyzes pathways from grey to blue hydrogen, integration of CCUS with SMR and ATR, and challenges for green hydrogen, concluding that blue hydrogen serves a crucial transitional role until green hydrogen becomes economically viable.

📄 Abstract（原文）
The worldwide transition to a low-carbon energy framework has established hydrogen as an essential decarbonisation mechanism, especially for challenging industrial sectors to decarbonise. The environmental advantages of hydrogen depend on its manufacturing method. Conventional "grey" hydrogen generation, mostly reliant on fossil-based technologies, is a major contributor to CO2 emissions. This analysis examines the relationship between the hydrogen economy and carbon capture, utilisation, and storage (CCUS) technologies, facilitating the generation of "blue" hydrogen as a lower-carbon transitional fuel. The research methodically examines contemporary hydrogen generation methods, emphasising the integration of carbon capture, utilisation, and storage (CCUS) with steam methane reforming (SMR) and autothermal reforming (ATR). It offers a comprehensive analysis of post-combustion, pre-combustion, and oxyfuel carbon capture systems, assessing their maturity, efficiency, and retrofit capability. The research delineates critical obstacles confronting both "green" (electrolysis-based) and "blue" hydrogen, including elevated prices, technical underdevelopment, energy inefficiencies, and public acceptability concerns. The review asserts that although green hydrogen embodies the ultimate sustainable objective, blue hydrogen, supported by CCUS, serves a crucial transitional function in decarbonising the current hydrogen supply and industrial framework, bridging the divide until renewable hydrogen achieves economic and technological feasibility at scale.
