日本語
従来の水素利用研究は地質学的に生成される水素（gH2）を考慮していなかった。本論文では、gH2が低コスト（1$/kg）で豊富に存在する場合、水素の利用が発電など多様な分野に拡大する可能性を示す。一方、コストが人工水素に近づくと利用は急速に減少する。
English
Previous studies ignored geologic hydrogen (gH2). This paper shows that if gH2 is abundant and cheap ($1/kg), it could expand hydrogen use broadly, especially in power generation. However, deployment is sensitive to cost, declining rapidly as it approaches manufactured hydrogen cost.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は水素社会の実現を目指しており、天然水素の存在は国内の水素調達に新たな可能性をもたらす可能性がある。ただし、本論文は発電部門への影響を主に分析しており、日本のGX政策との直接的な関連は限定的だが、水素戦略の再検討に示唆を与える。
In the global GX context
This paper introduces geologic hydrogen as a potentially game-changing resource for global decarbonization, shifting hydrogen from a niche fuel to a major energy carrier. It provides critical insights for energy transition modeling and hydrogen investment strategies.
👥 読者別の含意
🔬研究者:Energy system modelers should incorporate gH2 scenarios to assess its potential impact on decarbonization pathways.
🏛政策担当者:Policymakers should consider geologic hydrogen in national hydrogen strategies and resource exploration policies.
📄 Abstract（原文）
Previous studies on the use of hydrogen (H2) in the future energy system typically find a limited role for the energy carrier; however, these studies have not accounted for geologic H2 (gH2), which by some estimates may be abundantly available at low cost. Consequently, hydrogen’s role in the energy system could shift from a minor contributor, deploying mostly in difficult-to-decarbonize sectors, to a much more prominent element of the global energy system. In this paper we examine the role of gH2 for global energy and industrial systems with different scenarios of future radiative forcing. We find that if favorable conditions exist, where gH2 is abundant and inexpensive ($1/kg), it could lead to expanded hydrogen deployment in a wide variety of energy applications, with power generation the most notable. However, deployment of gH2 is also found to be sensitive to its production cost, with its use declining rapidly as its production cost approaches the cost of manufactured hydrogen.
