📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
CCUSは日本政府が推進するGX戦略の重要技術。本成果は、従来のアミン吸収法に比べ大幅な省エネと低コスト化を実現し、日本の産業界（鉄鋼・化学など）での導入障壁を下げる可能性がある。SSBJやグリーン成長戦略とも整合する基盤技術。
In the global GX context
Globally, CCUS is essential for meeting net-zero targets, and this paper directly addresses the two main barriers: energy consumption and cost. The pulsed microwave approach could be a breakthrough for scalable CO2 capture in hard-to-abate sectors, aligning with IEA and IPCC pathways for carbon removal.

📄 Abstract（原文）
Carbon dioxide (CO2) capture with energy duty of below 2.0 MJ·kg−1 CO2 is the global prospect in the decarbonization process. Herein, we present a microwave-responsive amine sorbent coupled with a pulsed microwave regeneration (AS-MR) process that achieves rapid and fully regeneration of amine sorbent within 2 seconds of microwave pulse. By matching the energy input with the desorption rate, ultra-low energy duty of 1.02 MJ·kg−1 CO2 can be achieved for sorbent regeneration and 1.21 MJ·kg−1 CO2 for the AS-MR system during an adsorption-desorption cycle. Insights into the mechanism indicate that the directional electric field aids the CO2 desorption process by weakening and polarizing the C-N bond in the carbamate acid state. Techno-economic analysis and life cycle assessment demonstrate the sustainability of this technology with costs below $20·tonne−1, directly responding to the pressing demand for economically viable decarbonization technologies in challenging industrial sectors.
