📄 Abstract（原文）
Global greenhouse gas emissions continue to rise, with 2024 marking the highest annual levels on record despite the rapid and unprecedented growth in renewables. Achieving rapid and deep emission reductions requires large-scale deployment of Carbon Capture, Utilisation and Storage (CCUS), which is included as a critical component in all major net-zero pathways. However, the high cost of CO₂ capture remains one of the most significant barriers to accelerating CCUS adoption.Among capture methods, solvent absorption is the most widely applied for pointsource emissions, yet it is highly energy-intensive-over 80% of the total energy demand arises from solvent regeneration. Studies indicate that energy consumption accounts for around 40% of the operating cost of CO₂ capture, highlighting the urgent need for energy-efficient regeneration strategies. This paper presents CO2CRC's novel hybrid capture technology, which addresses the challenges of large footprint and energy consumption by significantly reducing solvent regeneration costs. This novel technology meets the challenges through lower regeneration temperatures, reduced steam consumption, elimination of solvent phase change during regeneration, and the potential integration of waste heat. Together, these innovations demonstrate a pathway to lowering capture costs and enabling broader deployment of CCUS in support of global decarbonisation.
