本研究は、商業規模の炭素負バイオマスガス化システムと有機ランキンサイクル（ORC）発電を統合した技術経済評価を提示する。45MWのアップドラフトガス化施設をモデル化し、3つのシナリオを評価。電力のみではLCOE 11.30 c/kWh、IRR 14-16%だが、バイオチャーを400ドル/tで含めるとLCOE 5.80 c/kWh、IRR 22-26%に改善。さらにインセンティブとCDRクレジットを含めるとLCOE 3.20 c/kWhとなる。
English
This study presents a techno-economic assessment of a commercial-scale carbon-negative biomass gasification system integrated with ORC power generation. A 45 MW updraft gasification facility is modeled under three scenarios: electricity-only yields LCOE of 11.30 c/kWh and IRR of 14–16%; adding biochar at $400/t reduces LCOE to 5.80 c/kWh and raises IRR to 22–26%; with incentives and CDR credits, LCOE drops to 3.20 c/kWh. Viability is driven by multi-product revenue rather than electricity alone.

📝 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のFIT依存からの脱却が課題となる中、バイオチャーやCDRクレジットを組み合わせた多製品収益モデルは、再エネ事業の自立化と炭素除去市場の活用に向けた示唆を提供する。特にJ-クレジット制度やGX推進政策との連携が期待される。
In the global GX context
This paper contributes to the global dialogue on carbon removal and negative emissions technologies, showing how multi-product revenue (biochar, CDR credits) can make biomass gasification viable without subsidies. It aligns with voluntary carbon market MRV standards and informs transition finance for hard-to-abate sectors.
👥 読者別の含意
🔬研究者:Provides a detailed techno-economic model for carbon-negative biomass systems, highlighting the role of biochar and CDR credits in improving project bankability.

📄 Abstract（原文）
Thermochemical renewable energy projects have historically struggled to achieve commercial viability without substantial incentives, often failing to progress beyond the “technology valley of death.” Even when scaled, underperformance and high capital costs have limited competitiveness with fossil-based systems. These challenges are frequently linked to undercapitalized development structures and inflated capital expenditure assumptions. This study presents a techno-economic assessment of a commercial-scale, carbon-negative biomass gasification system integrated with Organic Rankine Cycle (ORC) power generation. A 45 MW updraft gasification facility is modeled under a cradle-to-grave boundary, with carbon permanence defined by H/Corg < 0.4 and MRV aligned with voluntary carbon markets. Three scenarios are evaluated. Electricity-only results in LCOE of 11.30 c/kWh and IRR of 14–16%. Including biochar at $400/t reduces LCOE to 5.80 c/kWh and increases IRR to 22–26%. For the third scenario which includes incentives and voluntary market CDR credits the LCOE is 3.20 cents/kWh. Results confirm that viability is driven by multi-product revenue rather than electricity alone.
