Abstract

The atmospheric levels of CO₂ have reached levels never seen before due to industrialization. This highlights the need for scalable, reliable, and economical carbon capture solutions. In this review, the author evaluated hybrid physical-chemical absorption systems. This absorption system combines high capture efficiency from physical solvents and the selectivity of chemical absorption. The major systems reviewed include solvent mixtures, membrane-assisted absorption, solid-supported amines, and desublimation hybrid systems. These were assessed on energy consumption, stability, sustainability, and deployment possibilities. The author concluded that hybrid systems could use 15-30 % less regeneration energy than traditional monoethanolamine-based capture. In addition, the hybrid systems can be produced with increased durability and operational flexibility. As of 2025, China is the world's largest emitter of CO₂and therefore represents a strong case study for assessing the pathways for large-scale implementation. The current research indicates strong technical viability but also reveal challenges such as solvent degradation, corrosion risks, and limited scale-up capacity. In conclusion, combining technology progress, technological and economic assessments, and policy frameworks, show that hybrid absorption is a viable and promising path toward decarbonization.
