📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はGX基本方針で水素供給拡大を掲げるが、本論文は気候変動が水素コストに地域差をもたらすことを示し、日本の海外調達戦略や国内立地選定に示唆を与える。特に、日本が依存する東南アジアからの輸入でコスト低下が見込める一方、国内生産では気候影響の評価が重要となる。
In the global GX context
This paper provides critical insight for global hydrogen investment planning, showing that climate change will alter cost competitiveness of green hydrogen across regions. For investors and policymakers, it underscores the need to incorporate climate projections into project feasibility studies and grid planning, especially as countries scale up hydrogen hubs.

📄 Abstract（原文）
Meeting global decarbonization targets requires large-scale, low-carbon hydrogen (H2) production around mid-century. A crucial pathway for this production is electrolysis driven by renewables, tying hydrogen production and costs to spatially varying renewable resources. The potential, variability, and complementarity of renewable resources, though, will be affected by climate change. We quantify the impact of climate change on renewable-energy generation for H2 production globally. We use an investment and operations optimization model for hydrogen systems to estimate geographically explicit and regionally aggregated levelized cost of hydrogens (LCOHs) under historical and future climates. We find climate change could raise the cost of green-hydrogen production by up to 20% in some global locations, and about 16% of global locations could see LCOH increases or decreases exceeding 5%. Southeast Asia and Europe in particular see LCOH reductions due to climate change, while North America sees LCOH increase. Most locations, though, see modest impacts of climate change on hydrogen costs. We also find modest cost consequences from climate change for locations with active hydrogen development. Our results highlight the need for proactive investment strategies to accommodate the climatic variations affecting renewable hydrogen production, especially in countries with stricter H2 power-grid import limits and with firm H2 demand for industrial processes.
