Global climate and ecological crisis urge to decarbonazation of EU through sustainable low carbon alternatives to achieve carbon neutrality by 2050. Within this context, Power-to-Hydrogen-to-Power (P2H2P) technologies are playing an essential role in the energy transitions boosting the energy system flexibility, facilitating the integration of renewable energy sources and providing a promising pathway for long-term energy storage and clean fuel supply. Driving forces behind this research are the imperative raise the usage of clean fuels in industry, the optimization of combined cycle operation and the grid balancing challenge achieved by the implementation of energy storage. In this study, the methodological framework of a P2H2P system is developed, and a comprehensive approach that can be applied in similar systems is determined. Particularly, the boundaries include all the stages of P2H2P such as the hydrogen production, the hydrogen compression and storage, as well as the power production. The present study aims to evaluate the environmental impact of an innovative P2H2P system integrated with energy storage, developed and demonstrated within a real combined cycle power plant. Specifically, this study estimates the environmental performance indicators associated with hydrogen production and power generation through co-combustion of natural gas and hydrogen. The life cycle assessment (LCA) outcomes highlight the potential of such integrated solutions to enhance energy system flexibility and support the EU�s long-term carbon-neutrality goals. This study demonstrates that coupling LCA with real-scale operational data is crucial for guiding the sustainable deployment of next-generation hydrogen technologies.
