日本語
本論文は、電解触媒によるCO2還元（CO2RR）の産業規模での実装に向けた全チェーンのボトルネックを体系的に分析する。触媒安定性、電解槽スケールアップ時の物質移動、製品分離・精製の高エネルギー消費、間欠的再生可能エネルギーと連続運転のミスマッチ、基礎研究と工学応用の連携不足といった課題を整理。さらにコスト競争力の弱さや投資回収期間の長さ、不完全な炭素価格メカニズムといった経済的要因も指摘し、政策支援と学際的統合の重要性を強調する。
English
This review systematically analyzes full-chain bottlenecks hindering industrial-scale electrocatalytic CO2 reduction (CO2RR). It examines challenges across four core modules—catalysts, electrolysis systems, product separation, and system integration—including catalyst stability at high current density, mass-transfer issues in scale-up, high energy consumption, and mismatches between intermittent renewables and continuous operation. Economic constraints such as weak cost competitiveness, long payback periods, and imperfect carbon-pricing mechanisms are also discussed, emphasizing the need for research-engineering synergy, policy support, and interdisciplinary integration.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
CO2RRはカーボンリサイクルの中核技術として、日本のGX実現に向けた産業脱炭素化・炭素循環の鍵となる。炭素価格メカニズムや投資回収期間への言及は、日本企業の脱炭素投資判断や政策設計に示唆を与える。
In the global GX context
CO2RR is a core carbon-recycling technology relevant to global net-zero pathways and industrial decarbonization. The paper's focus on carbon-pricing mechanisms and investment-return periods connects to transition-finance debates and policy frameworks like the EU ETS and carbon contracts for difference, offering a full-chain perspective valuable for scaling CCU beyond lab scale.

📄 Abstract（原文）
Electrocatalytic CO 2 reduction (CO 2 RR) converts CO 2 into high‐value chemicals and fuels using renewable electricity, serving as a core technology for recycling of carbon resources and supporting the carbon neutrality goal. Nevertheless, multiple bottlenecks hinder its transition toward industrial‐scale application. These include poor catalyst stability under industrial‐level high current density, uneven mass transfer and limited durability of key components during electrolyzer scale‐up, high energy consumption together with difficult product separation and purification, mismatches between intermittent renewable energy supply and continuous electrolysis operation, as well as insufficient synergy between fundamental research and engineering applications. Economic factors also constrain industrialization, such as weak cost competitiveness, long investment‐return periods, and imperfect carbon‐pricing mechanisms. Aiming at the full‐chain industrial implementation of CO 2 RR, this paper systematically analyzes the challenges and underlying mechanisms of four core modules: catalysts, electrolysis systems, product separation, and system integration. It reviews the latest technological breakthroughs and feasible solutions, emphasizing the importance of fundamental research‐engineering synergy, policy support, and interdisciplinary integration. This work provides a systematic reference and rational development direction for scientific research breakthroughs and industrial transformation of CO 2 RR technology.
