ナイジェリアのCCUS統合型再エネ貯蔵システムについて、139名の専門家調査とHYSYS・HOMERシミュレーションを組み合わせて評価した。最大の障壁は高資本コスト（58%）で、規制不確実性（51%）と技術人材不足（50%）が続く。CO2回収効率は93%超と高い一方、補機動力増・プロセス複雑化・資本リスクが確認され、技術準備は中程度だが金融・規制・炭素市場の準備は弱いと結論づけた。
English
This study assesses stakeholder readiness and institutional barriers for carbon-capture-integrated renewable energy storage in Nigeria, triangulating a 139-respondent survey with Aspen HYSYS process simulation and HOMER Pro optimization. High capital cost (58%), regulatory uncertainty (51%), and technical-capacity constraints (50%) were the leading barriers, while 78% viewed CCUS as important to decarbonization. Simulations showed >93% CO2 capture efficiency but higher auxiliary demand and capital exposure, indicating moderate technical readiness but weak financial, regulatory, and carbon-market readiness.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業が新興国でCCUS・再エネ貯蔵事業を展開する際の制度的リスク評価の参考になる。ただし日本のSSBJ・有報開示や国内政策との直接の接続は薄い。
In the global GX context
Adds emerging-market evidence to the global CCUS and transition-finance literature, highlighting how regulatory uncertainty and carbon-market immaturity constrain deployment—relevant to ISSB-aligned disclosure of transition risks in developing economies.

📄 Abstract（原文）
This study evaluates stakeholder readiness and institutional barriers affecting carbon-captureintegrated renewable energy storage systems in Nigeria. A structured survey produced 139 valid responses from engineering, management, regulatory, academic, project-delivery, and industrial-energy professionals. Survey evidence was triangulated with Aspen HYSYS process-simulation results and HOMER Pro system-optimization outputs. High capital cost was the leading barrier, identified by 58% of respondents, followed by regulatory uncertainty at 51% and technical-capacity constraints at 50%. Although 78% considered carbon capture, utilization, and storage important or highly important to Nigeria’s decarbonization pathway, familiarity with amine-based capture was substantially lower than familiarity with solar photovoltaic and battery systems. Process modelling indicated carbon dioxide capture efficiencies above 93%, while also confirming increased auxiliary demand, process complexity, and capital exposure. The combined evidence indicates moderate technical readiness but weaker financial, regulatory, and carbon-market readiness. A phased pathway is recommended, comprising a dedicated CCUS framework, blended finance, demonstration projects, workforce development, credible carbon accounting, and transparent stakeholder engagement.
