コロンビアの紛争後農村地域において、パーム油の廃棄物（房だか）からの水素製造を技術・環境・経済の観点から評価。大規模プラント（ボリーバル）では高い変換効率と経済的実行可能性を示し、GHG排出量は2.47 kg CO2 eq/kg H2と化石由来水素より大幅に低かった。一方、小規模プラント（サンタンデール）は経済的に非現実的であった。原料組成とプロセス収率の非線形関係が技術的課題として確認された。
English
This study assesses hydrogen production from palm oil rachis in post-conflict rural Colombia. A large-scale plant in Bolívar achieved high conversion efficiency, low GWP (2.47 kg CO2 eq/kg H2), and economic viability (NPV $25M), while a small-scale plant in Santander was unfeasible. Non-linear feedstock-process yield relationships were identified as a key technical challenge.

📄 Abstract（原文）
The global push for energy decarbonization has increased interest in hydrogen as a clean energy carrier. Biohydrogen from agricultural residues is a promising pathway for countries with strong agro-industrial sectors. This study evaluates the technical, economic, and environmental feasibility of hydrogen production from palm oil rachis in two post-conflict regions of Colombia: a large-scale facility in Bolívar and a small-scale plant in Santander. The assessment integrates Aspen Plus® (version 14) simulations using the NRTL thermodynamic model, an attributional gate-to-gate Life Cycle Assessment (LCA) with ReCiPe Midpoint (H), and a techno-economic analysis. The simulated process includes biomass drying, decomposition, steam gasification, syngas cleaning, and methane reforming. A key technical finding was the non-linear relationship between feedstock composition and process yield. Although Santander’s biomass had a higher hydrogen content (9.42% vs. 6.58%), Bolívar achieved a much higher conversion efficiency (0.198 kg H2/kg biomass) and produced over seven times more hydrogen while processing only 5.8 times more biomass. Environmental results showed clear advantages for Bolívar, which presented lower impacts across most categories compared to Santander and the fossil-based hydrogen benchmark. Bolívar achieved a Global Warming Potential of 2.47 kg CO2 eq/kg H2, far below the 15.03 kg CO2 eq/kg H2 of Santander, and showed favorable performance in particulate matter formation, acidification, and fossil resource scarcity. Economically, Bolívar was viable, with a Net Present Value of USD 25.01 million, a Benefit–Cost Ratio of 3.29, and a discounted payback period of 4.54 years. Santander was economically unfeasible under all conditions. Hydrogen production from palm rachis is technically feasible, environmentally beneficial, and economically viable when biomass availability and process integration are adequate, as illustrated by the Bolívar case.
