ブラジルの低炭素水素規制を、1931年から2025年半ばまでの法令をPythonで体系的に収集・整理する混合手法で分析。上位法の整備に対し、技術基準・国際認証・投資リスク低減の下位規則が欠如し、制度の断片化と所管重複が投資障壁となっていることを明らかにした。法の野心と規制の実態の乖離が、大規模投資を妨げる主要因だと結論づける。
English
This study maps Brazil's low-carbon hydrogen regulations from 1931 to mid-2025 using Python-based normative mapping plus qualitative content analysis. It finds a disconnect between comprehensive high-level laws and missing sub-legal rules: fragmented governance, absent technical and certification standards, and no financial de-risking mechanisms. This gap creates legal and economic uncertainty that blocks large-scale investment.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は水素の国際サプライチェーン構築を進めており、ブラジルは有望な供給候補国の一つ。本稿は供給国側の規制・認証・投資リスクの実態を示し、日本企業の水素調達・海外投資判断や、国際的な水素認証制度の相互運用性を検討する上で示唆を与える。
In the global GX context
As global hydrogen trade scales, this paper shows how a major potential exporter's regulatory gaps—certification, governance, and de-risking—shape bankability and cross-border offtake. It adds to transition-finance and disclosure scholarship by linking legal-institutional design to investability in emerging hydrogen markets.
👥 読者別の含意
🔬研究者:新興国における水素規制の制度設計と投資リスクの関係を実証的に示す事例研究として有用。
🏢実務担当者:ブラジルでの水素調達・投資を検討する際、認証・契約・規制リスクの評価に活用できる。
🏛政策担当者:水素産業育成には上位法だけでなく、技術基準・認証・金融支援の下位規則整備が不可欠という教訓を提供。
📄 Abstract（原文）
Low-carbon hydrogen is emerging as a key vector in the global energy transition and Brazil, with its vast renewable energy potential, is uniquely positioned to become a leading global supplier. This article investigates the current state of Brazil’s regulatory framework for low-carbon hydrogen, moving beyond a mere inventory of laws to conduct a critical analysis of its institutional design, normative gaps, and policy challenges. Employing a mixed-methods approach, the study first conducts a systematic normative mapping, using Python scripts to collect and organize an extensive database of legislative and administrative acts from 1931 to mid-2025. This quantitative inventory is followed by a qualitative content analysis of key legal instruments and policy documents to identify substantive gaps and institutional misalignments.The findings reveal a significant disconnect between Brazil's comprehensive high-level legal frameworks and the critical absence of detailed sub-legal regulations. This gap manifests in three key areas: (i) an institutional framework marked by fragmented governance and overlapping agency mandates; (ii) a lack of essential regulations concerning technical standards for infrastructure and internationally compatible certification criteria; and (iii) the absence of financial mechanisms to de-risk private investment, such as state-backed incentives and standardized offtake agreements.The study concludes that this gap between legislative ambition and regulatory reality creates a high-risk environment of legal and economic uncertainty which acts as the primary barrier for the large-scale investment necessary for Brazil to establish a competitive hydrogen industry and fulfill its potential in the global market.
