 This paper provides an overview of the current state of research into hydrogen-based energy storage systems. It examines the evolution of research trends and the design of energy systems associated with hydrogen technologies and identifies potential areas for future research. The authors found that the majority of research is focused on simulation studies, which are mainly concentrated in South America, Africa, East Asia and Oceania. There is a lack of collaboration between these regions, which could lead to more efficient research outcomes. Additionally, the authors propose future research directions related to optimizing the economic, environmental, and operational aspects of hydrogen-based energy storage systems.
