In this context, green hydrogen (GH), produced from renewable sources (RS), has emerged as a promising alternative for the decarbonization of industrial and transportation sectors. However, its large-scale implementation still faces technical, economic, and structural barriers. Industrial symbiosis (IS) has emerged as a strategic approach to address some of these challenges by enabling waste utilization, integration between production processes, and optimization of energy resources. This study aimed to construct technological roadmaps (TR) focused on GH production with an emphasis on IS applications. TR made it possible to map technological challenges, identify innovation opportunities, and outline potential synergies among industrial sectors, considering different time horizons: short-, medium-, and long-term. This approach contributed to the definition of strategic pathways aimed at the efficient and environmentally responsible industrial implementation of GH. The results depicted that electrolysis combined with renewable energy occupies a central position in technological strategies; and depicted the relevance of process integration as an industrial technological strategy. Furthermore, collaborative research networks and interdisciplinary approaches are pathways capable of enhancing the technological and operational maturity of the field, allied to the establishment of a solid innovative ecosystem as the main impact on IS industrial applicability. And some perspectives to be highlighted in order to promote the integration between GH and IS comprise the use of computational modeling and optimization, economic and environmental assessment based-on life-cycle studies, support by means public policies, and enabling technologies as internet of things and artificial intelligence.  aAlternative energy industry  aEnergy  aGreenhouse gases  aHydrogen  aEfeito Estufa  aEnergia  aHidrogênio  aInovação1 aVAZ JUNIOR, S.  tSustainable Chemistry and Pharmacygv. 51, 102424, June 2026.
