本研究は、サトウキビ由来バイオガスを燃料とするAllam-Fetvedtサイクル発電所の技術的・経済的実現可能性を評価。二つのバイオガス生産シナリオ（年間800万トンと2400万トンのサトウキビ処理）を想定し、Aspen Plusでシミュレーション。経済分析では設備投資は高いが、発電コスト（LCOE）が大規模化により低下（1443→848 R$/MWh）。BECCSとして負の排出を実現する有望な技術経路を示す。
English
This study evaluates the technical and economic feasibility of an Allam-Fetvedt Cycle power plant fueled by sugarcane-derived biogas for BECCS. Two scenarios (8 and 24 million tons sugarcane/year) are simulated using Aspen Plus. Economic analysis shows high capital costs but significant LCOE reduction from 1443 to 848 R$/MWh with scale. The integration offers a promising pathway for negative-emission power generation, though further optimization is needed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではバイオマス発電が普及しているが、CCSとの組み合わせ（BECCS）はまだ限定的。本論文はAllam-Fetvedtサイクルという最新技術とバイオガスを組み合わせた点が新規で、日本のバイオマス発電事業者や政策立案者にとって参考になる。特にサトウキビ以外の原料（国産バイオマス）への応用可能性が今後の課題。
In the global GX context
This paper presents a novel integration of the Allam-Fetvedt cycle (inherent CO2 capture) with biogas from sugarcane for BECCS. For global audiences, it offers a detailed techno-economic assessment of a promising negative-emission technology, with LCOE estimates that show potential for cost reduction at scale. This is relevant for countries with abundant biomass resources and interest in carbon removal.
👥 読者別の含意
🔬研究者:GX researchers should note the detailed process simulation and LCOE analysis for a novel BECCS configuration; the results provide a baseline for comparison with other CCUS pathways.
🏢実務担当者:Corporate sustainability teams in the power or agriculture sectors can assess the viability of integrating biogas with advanced carbon capture cycles for negative emissions.
🏛政策担当者:Policymakers may consider the role of BECCS in national decarbonization strategies, noting the scale-dependent economics and the need for further R&D support.
📄 Abstract（原文）
The development of energy technologies with low CO2 emissions is increasingly important for achieving the United Nations Sustainable Development Goals. In this context, power plants based on the Allam-Fetvedt Cycle appear promising because this cycle (introduced in 2012) features inherent CO2 capture. In this context, its association with biogas as fuel enables its application as a Bioenergy with Carbon Capture and Storage (BECCS) system. This study evaluates the technical, energetic, and economic feasibility of an Allam-Fetvedt Cycle power plant fueled by biogas. The methodology is based on detailed process simulations performed using Aspen Plus® v14. Two biogas production scenarios were assessed: Case 1 and Case 2, corresponding to the processing of 8 and 24 million tons of sugarcane per year, respectively. The economic analysis indicated a high capital investment, primarily in the Air Separation Unit (ASU) and the Balance of Plant (BOP). Nevertheless, a significant reduction in the Levelized Cost of Energy (LCOE) was observed, decreasing from 1443 R$/MWh (€0.227/kWh) in Case 1 to 848 R$/MWh (€0.134/kWh) in Case 2. Overall, the results suggest that integrating biogas into the Allam-Fetvedt Cycle represents a promising technological pathway for power generation with negative carbon emissions. Further research and optimization are required to improve economic viability and strengthen the role of this technology as a strategic option for decarbonizing the energy sector.
