Hydrogen (H2) is increasingly cited as a key element of future sustainable energy systems. Environmental assessment of H2 production is gaining importance in meeting climate goals. While current literature mainly focuses on reducing CO2 emissions, other life cycle impacts – such as effects on ecosystems, human health, and resource use – are often underestimated. In the Hungarian context, this study represents the first attempt to estimate the environmental impacts of the national Hydrogen Strategy. This study aims to fill this gap through a quantitative environmental evaluation of hydrogen production pathways projected in the Hungarian Hydrogen Strategy. Based on life cycle assessment (LCA) using the Sphera database, three major production technologies were modelled: steam methane reforming (grey), reforming with carbon capture (blue), and solar PV-based electrolysis (green). Results show that the total environmental burden of hydrogen production in Hungary could be halved by 2050 compared to 2020, while the specific carbon footprint of H2 production could be 75 % lower than today. However, this projection excludes expected efficiency improvements, as much of the future capacity has yet to be built.
