日本語
コロンビアの248の最終処分場を対象に、埋立地ガス由来の水素供給ポテンシャルを2026〜2040年について評価したコードとデータの公開。廃棄物堆積量を一次減衰モデルで再現し、メタン回収量、水蒸気改質とアルカリ電解の2経路の水素量・均等化コスト・炭素強度を算出。モンテカルロ法で不確実性を伝播させ、サイト別のアトラスを構築している。
English
Open code and input data for a site-resolved national assessment of hydrogen from landfill gas at Colombia's 248 active disposal sites (2026-2040). It models waste deposits with first-order decay, estimates recoverable methane, and computes hydrogen output, levelized cost and cradle-to-gate carbon intensity for steam reforming and landfill-gas-powered electrolysis, propagating uncertainty via 10,000 Monte Carlo realizations.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では廃棄物処理・水素供給の脱炭素化はGX政策の周辺領域だが、廃棄物由来水素のコスト・炭素強度を全国規模でサイト別に可視化する手法は、自治体・事業者の水素導入検討や地域脱炭素計画に応用可能な示唆を持つ。
In the global GX context
Adds a replicable, open, site-resolved methodology for waste-to-hydrogen that complements global hydrogen and circular-economy decarbonization pathways; relevant to transition finance and national hydrogen strategies, though not tied to TCFD/ISSB disclosure frameworks.
👥 読者別の含意
🔬研究者:Provides an open, reproducible framework for site-level waste-to-hydrogen potential, cost and carbon-intensity assessment with uncertainty propagation.
🏢実務担当者:Offers a template for screening landfill sites as hydrogen feedstock and comparing reforming vs electrolysis economics.
🏛政策担当者:Illustrates how national waste and hydrogen strategies can be linked through site-resolved resource mapping.
📄 Abstract（原文）
Code and input data of a site-resolved national assessment of the hydrogen that the landfill gas of the 248 disposal sites active in Colombia in 2024 could supply between 2026 and 2040, through catalytic steam reforming with pressure swing adsorption or through alkaline electrolysis powered by landfill-gas electricity. For every site, the code reconstructs the deposits of municipal solid waste, estimates the methane they generate with a first-order decay model and the part that a collection field would recover, and calculates the hydrogen of both routes, its levelized cost and its cradle-to-gate carbon intensity, with a Monte Carlo propagation of the uncertainty over 10,000 realizations. It also includes a thermodynamic balance of the reformer island, checks of the reformer cost fit, consistency checks against the methane recovered at nine sites, and variants of operation, collection efficiency, dependence between sites and cost. The inputs are the final-disposal registry of the Superintendency of Residential Public Services (SSPD), harmonized into 1,868 sites, the population projections and codes of the National Administrative Department of Statistics (DANE), the municipal boundaries of the Agustín Codazzi Geographic Institute (IGAC), the climate normals of the IDEAM, the MSW characterizations of 56 municipal plans and of the Mining and Energy Planning Unit (UPME), and the public records of recovered methane. From them, the code computes the results reported in the article A Site-Resolved Atlas of Potential, Cost and Carbon Intensity for Green Hydrogen from Landfill Gas in Colombia (Hydrogen, MDPI).
