この論文は、CCU（二酸化炭素回収・有効利用）の戦略的再定義として、排出源回避、炭素集約型製品の代替、再生可能エネルギーとの統合の3経路を提示。従来の炭素循環を超え、尿素代替、バイオジェニックCO2利用、水素キャリアとしてのCO2利用による永久貯留など、スケーラブルな産業脱炭素を提案する。
English
This perspective redefines CCU beyond conventional cycling by outlining three strategic pathways: replacing high-emission fossil products, sourcing CO2 from biogenic streams for near-neutral cycles, and using CO2 as a hydrogen carrier for permanent storage via concrete mineralization. It argues that with falling renewable costs, industrial co-location, and policy support, CCU can scale to contribute to industrial decarbonization.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではGX政策の一環としてCCS・CCUの推進が掲げられており、本論文はCCUを産業脱炭素の実用的手段へと位置づける視点を提供する。特に、CO2を水素キャリアとして利用する経路は、日本の水素社会戦略とも連動しうる。
In the global GX context
Globally, CCU is gaining traction as a complement to CCS. This paper reframes CCU from a simple cycle to a strategic tool for substitution, biogenic carbon use, and energy transport, which is relevant for ISSB/TNFD reporting on climate transition plans and for technology investors evaluating CCU pathways.

📄 Abstract（原文）
Carbon capture and utilization (CCU) mitigates climate change by converting CO2 into fuels, chemicals, and construction materials. From a life-cycle perspective, CCU benefits arise from preventing point-source emissions, substituting for carbon-intensive products, and coupling with renewable energy to lower upstream impacts. However, high energy needs, feedstock costs, and capture requirements continue to limit large-scale deployment. This perspective reframes CCU beyond conventional cycling by outlining three strategic pathways: replacing high-emission fossil products such as urea to maximize substitution benefits even when CO2 is later re-emitted; sourcing CO2 from biogenic streams to create near-neutral cycles; and using CO2 as a hydrogen carrier that transports energy and enables subsequent permanent storage through concrete mineralization. Combined with falling renewable electricity costs, industrial co-location, and targeted policy support, CCU can progress from niche demonstrations to a scalable contributor to industrial decarbonization and climate-neutral production.
