Green Hydrogen Production Costs Could Nearly Double Under Round-the-Clock Off-Grid Supply, Fraunhofer ISE Analysis Finds

Most quantitative figures and references in both the long and short versions match recent Fraunhofer CINES publications and broader hydrogen cost literature. However, several specific numbers (e.g., €1–2.5/kg penalty, >€10/kg extra cost, USD 18–22/kg vs 4–6/kg, pilots in Spain and Australia) are not directly traceable to a publicly available Fraunhofer ISE study or Hydrogen Insight report and remain unverifiable. Overall framing is plausible but partly speculative.
