日本語
ポーランドの商業電力向けバイオマス資源を5分類で棚卸しし、理論量・技術的可採量・持続可能管理の各シナリオで供給不足とCO2収支を検証した。現行需要に対し約20%の燃料不足、2050年には最大60%の不足が生じる。燃焼時CO2をバイオマス成長時の吸収で相殺することは不可能で、技術水準で20%、持続可能管理で30%の不均衡となる。
English
This study inventories Poland's energy biomass across five categories and tests theoretical, technical, and sustainable-management scenarios against demand and CO2 balance. It finds roughly 20% fuel shortfall versus current demand, rising to up to 60% by 2050. Balancing combustion CO2 with biomass growth uptake proves infeasible, with imbalances of 20% (technical) and 30% (sustainable management).

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
バイオマスをnet-zero電源とみなす前提に国規模で疑問を呈する点は、日本企業の再エネ調達・非化石証書やバイオマス発電のGHG算定を検討する際の参照材料になる。ただしSSBJや有報開示への直接的接続は弱い。
In the global GX context
Challenges the net-zero framing of biomass at national scale, relevant to GHG accounting debates under CSRD/ISSB on biogenic emissions and renewable eligibility. Offers a quantitative counterpoint to treating biomass combustion as carbon-neutral in corporate inventories.
👥 読者別の含意
🔬研究者:国規模でのバイオマスCO2収支の不均衡を定量化した実証として、バイオジェニック排出算定研究の参照になる。
🏢実務担当者:バイオマス調達や再エネ目標の達成可能性を評価する際、供給制約と炭素中立前提の限界を確認できる。
🏛政策担当者:バイオマスをnet-zero電源として優遇する政策設計の際、供給・炭素収支の制約を織り込む必要性を示す。
📄 Abstract（原文）
Climate change shifts governments’ focus to introducing policies that decrease the impacts of GHGs (among other emissions) generated by the energy production industry. Biomass is regarded as a net-zero emission source of renewable chemical energy, but analyses show that this is not true at the national scale. The purpose of this study is to determine the scale at which fossil fuels can be replaced with biomass in Poland. Different scenarios of biomass usage were analyzed—theoretical resources, technical possibilities, and sustainable bioresource management. Scenarios regarding the increase in energy demand alongside biomass CO2 coverage up to 2050 were also forecasted. An inventory of biomass resources in five categories suitable for energy use in the Polish commercial power industry revealed a fuel shortage of approximately 20% with respect to meeting the total current demand (2025), with critical shortages of up to 60% by 2050. Further analysis revealed the impossibility of balancing the carbon dioxide produced during biomass combustion for energy production. At current energy production levels, the theoretical potential is sufficient, but when technical feasibility is considered, the imbalance reaches 20% and, with sustainable resource management, even 30%. By 2050, 50% and 60% of the shortages at the technical and sustainability levels, respectively, will occur in the CO2 exchange system.
