本レビューは、CO2を燃料（メタノール、合成炭化水素、合成ガス）、化学品（尿素、ギ酸、炭酸塩、ポリマー）、材料（鉱物化・建設複合材）へ転換する経路を、触媒性能・変換効率・エネルギー需要・TRL・技術経済性の共通基準で横断比較する。CO2硬化コンクリートやドライリフォーミングが光触媒による炭化水素化より商業化に近い理由を、再生可能H2コストや触媒劣化などの共通ボトルネックとともに整理し、投資判断と政策課題を示す。
English
This review cross-compares CO2 utilization routes across fuels (methanol, synthetic hydrocarbons, syngas), chemicals (urea, formic acid, carbonates, polymers), and materials (mineralization, construction composites) using consistent criteria: catalyst performance, conversion efficiency, energy demand, TRL, and techno-economics. It identifies shared bottlenecks (renewable H2 cost, thermodynamic limits, catalyst deactivation, capture cost) and explains why routes like CO2-cured concrete and dry reforming are nearer commercialization than photocatalytic hydrocarbon synthesis, offering a cross-sectoral research and policy agenda.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はCCUS・カーボンリサイクルをGX推進戦略の柱に位置づけ、水素・合成燃料の商用化を急ぐ。本レビューは経路別のTRLと経済性を比較し、国内企業の投資選別や政府の技術ロードマップ策定に実務的な判断材料を提供する。
In the global GX context
Globally, CO2 utilization sits at the intersection of hard-to-abate decarbonization and carbon accounting, informing how firms claim emission reductions and how ISSB/CSRD disclosures treat recycled carbon. The review's TRL and techno-economic comparison helps investors and policymakers distinguish near-term deployable pathways from long-horizon R&D.

📄 Abstract（原文）
Abstract Carbon dioxide (CO 2 ) utilization has emerged as a promising pathway to convert a major greenhouse gas into value‐added products, offering both environmental and economic benefits. While CO 2 to fuel, CO 2 to chemical, and CO 2 to material conversion routes have each been reviewed extensively in isolation, existing literature rarely compares these three product streams against one another on a common basis of technology readiness, energy penalty and economic competitiveness with incumbent fossil‐derived routes leaving researchers and policymakers without a clear view of which CO 2 utilization pathways merit near‐term investment versus long‐term R&D. This review addresses that gap by critically synthesizing and cross‐comparing CO 2 conversion routes across fuels (methanol, synthetic hydrocarbons, and syngas), chemicals (urea, formic acid, carbonates, and polymers), and materials (mineralization and construction composites) using consistent criteria—catalyst performance, conversion efficiency, energy demand, technology readiness level, and techno‐economic viability. Rather than cataloguing individual studies, the review identifies the technical and economic bottlenecks common across pathways (renewable H 2 availability and cost, thermodynamic equilibrium limits, catalyst deactivation, CO 2 capture cost) and explains why some routes such as CO 2 cured concrete and dry reforming to syngas are closer to commercial deployment than others, such as CO 2 to hydrocarbon photocatalysis. The review concludes with a cross‐sectoral research and policy agenda for accelerating commercially viable, sustainable CO 2 utilization.
