ブラジル南部リオグランデ・ド・スル州を対象に、植林バイオマスのエネルギー潜在量を地理空間分析で評価した。石炭・バイオマス混焼による発電とBECCSを想定し、社会環境・水文・生物多様性の制約を除いた持続可能な供給可能量を推定。パンパ・スル発電所100km圏内で600MWe相当が得られ、設備容量345MWeを上回るが、水文制約が技術的潜在量を約60%減らす最大要因となった。
English
This study assesses sustainable energy potential from planted forestry biomass in Rio Grande do Sul, Brazil, for coal-biomass co-firing and BECCS as a just-transition strategy. Using geospatial analysis, it excludes socio-environmental, hydrological, and biodiversity-sensitive zones. Within 100 km of the Pampa Sul plant, biomass covers 180,450 ha, yielding ~600 MWe—exceeding the 345 MWe installed capacity—though hydrological constraints cut technical potential by ~60%.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では石炭混焼・アンモニア混焼やBECCSの実装可能性が議論されており、制約条件を組み込んだ持続可能なバイオマス供給量評価の手法は、国内の電源脱炭素化計画や地域の公正移行政策に示唆を与える。
In the global GX context
As global power sectors pursue defossilization, this work illustrates how spatially explicit sustainability constraints shape the realistic potential of biomass co-firing and BECCS. It contributes empirical evidence for just-transition planning in coal-dependent regions, relevant to transition finance and national decarbonization pathways.

📄 Abstract（原文）
This study aims at assessing the use of sustainability indicators for forestry biomass resources. It evaluates the energy potential of forestry areas in the state of Rio Grande do Sul, Brazil, for application in co-firing of coal and biomass for power generation as a mitigation strategy for a just transition in a coal-dependent region. Based on a geospatial analysis, eucalyptus plantation areas not overlapping with socio-environmental, hydrological, or biodiversity-sensitive zones were identified, defining a restrictive potential from which energy estimates were derived. Results indicate that, within a 100 km radius of the Pampa Sul Thermoelectric Power Plant, the existing forestry biomass covers 180,450.46 hectares. This corresponds to an estimated power potential of 600 MWe, which exceeds the plant’s installed capacity (345 MWe). However, hydrological constraints emerged as the main limiting factor, reducing by approximately 60% the initially estimated technical potential, followed by biodiversity and socio-environmental constraints respectively. Overall, our findings suggest that the sustainable use of planted biomass can support power sector defossilization while aligning environmental and socioeconomic objectives. Further studies are recommended to assess current biomass uses and the feasibility of utilizing forestry residues to ensure territorial and energy sustainability.
