It first identifies suitable hospital rooftops and nearby sites using multiple Digital Elevation Models (SRTM, Copernicus, ALOS) and land-cover, urban-density, and protected-area data to create a national “suitability” map. Focusing on three local facilities, in Vitro Building, Kenézy Gyula Hospital, and Medicover Debrecen, it calculates 10-year average solar radiation values (approximately 626, 792, and 686 kWh/m², respectively) via ArcGIS Pro’s Raster Solar Radiation tool. Case studies from the Netherlands’ Rijnstate and Spain’s Viamed San José hospitals demonstrate real-world green hydrogen integration. Results show strong technical viability for Debrecen’s hospitals to generate clean hydrogen and medical-grade oxygen on-site, potentially reducing carbon emissions and enhancing energy security. The work contributes a reproducible geospatial methodology for planning decentralized renewable-hydrogen energy in critical-infrastructure settings.14202 wordsenSolar-Powered Green Hydrogen ProductionHealthcare Facilities Energy TransitionRenewable Energy in HospitalsEnergy Policy and Regulations (Hungary)Green HydrogenGIS and Spatial Suitability AnalysisDecentralized energy systemRenewable energy integrationSustainable healthcare infrastructureEarth Sciences::Environmental GeographyEarth Sciences::Landscape Protection GeographyEarth Sciences::MeteorologyEarth Sciences::Természeti földrajzEnvironmental Science::Environmental ProtectionEarth Sciences::Regional Development PlanningHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
