In the present era, carbon emissions are experiencing a global upsurge. The greenhouse gas emissions are required to be brought down to net zero levels to attain environmental sustainability, with more reliance on renewable energy sources. To attain this, the role of green hydrogen generation becomes relevant in the realm of renewable energy. However, the storage and logistics of green hydrogen are complex and are inhibited by several challenges. This study systematically examines the interrelationships and influences among various roadblocks faced by the green hydrogen sector and offers a comprehensive analysis of the complex relationships between the key challenges by utilizing the DEMATEL (Decision-Making Trial and Evaluation Laboratory) approach. The findings contribute to a deeper understanding of the multifaceted barriers and provide a structured framework for policymakers, researchers, and industry stakeholders.
