本研究は、オーストラリア・クイーンズランド州における二酸化炭素回収・貯留（CCS）プロジェクトの経済的実行可能性を評価。統合型、マーチャント型、トーリング型の3事業モデルをCO2注入率やACCU価格シナリオ下で分析。年間300万トン以上の注入で商業的実行可能性が成立し、トーリング型ではACCU価格80豪ドルでもNPVがプラスになることを示した。
English
This study assesses the economic feasibility of carbon capture and storage (CCS) projects in Queensland, Australia. Three business models—integrated, merchant, and tolling—are tested under varying CO2 injection rates and ACCU price scenarios. Results show commercial viability at injection rates above 3 million tonnes per annum, with the tolling model maintaining positive NPV at ACCU prices as low as A$80/t.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でもCCSはGX実現の鍵とされるが、ビジネスモデルの経済性評価は限定的。本論文は排出者・回収者・注入者の役割分担とインセンティブ設計を示し、日本のCCS事業制度やJ-クレジットとの連携に示唆を与える。
In the global GX context
This paper provides a rigorous economic analysis of CCS business models under a carbon credit scheme (ACCUs) and declining emissions baselines. It offers valuable insights for global CCS deployment, particularly in designing contractual structures and pricing mechanisms that align emitter, capturer, and injector incentives.

📄 Abstract（原文）
Abstract This study evaluates the economic feasibility of carbon sequestration projects in Queensland, aimed at managing carbon dioxide (CO2) emissions from private coal-fired power plants. In Australia, the federal government issues Australian Carbon Credit Units (ACCUs) based on sequestered CO2 quantities, incentivizing emissions reduction. Under the Safeguard Mechanism, facilities emitting over 100,000 tonnes of CO2 annually must meet progressively tighter baselines, reduced by 4.9% per year from July 2023. This is expected to drive growth in ACCU demand and prices. Using publicly available well and geological data, we develop dynamic reservoir models to assess sequestration potential in Queensland. Three business models—integrated, merchant, and tolling—are tested under varying CO2 injection rates and ACCU price scenarios involving emitters, capturers, and injectors. Our analysis indicates that CO2 injection exceeding 3 million tonnes per annum (MTPA) meets commercial viability, with emitters showing interest once ACCU prices approach A$120/t. At 5 MTPA, emitters can feasibly engage even at A$100/t under the tolling model, which also offers flexible compensation structures maintaining a positive net present value at ACCU prices as low as A$80/t. We further propose models in which injectors receive service fees for CO2 storage, allowing emitters to secure ACCUs for compliance under the Safeguard Mechanism. Overall, these findings highlight the potential economic advantages and adaptability of sequestration projects, providing viable pathways for industry to align with government emissions targets.
