<p>The increasing popularity of electric vehicles and portable electronic devices worldwide is propelling the development of energy storage systems, including hydrogen storage and batteries. This growth aims for higher power and energy capacity, which relies heavily on the development of new materials. Energy storage materials are crucial for efficient and clean energy utilization and are vital to achieving the full potential of renewable energy sources. Perovskite oxides with the formula ABO₃ have been extensively studied for energy storage applications, particularly in electrochemical hydrogen storage systems, sodium-ion batteries, and lithium-ion batteries. This review presents recent advances in energy storage technologies based on perovskite compounds, with particular emphasis on sodium-ion batteries, lithium-ion batteries, and electrochemical hydrogen storage systems. The review focuses on two battery types, namely sodium-ion and lithium-ion batteries, and also provides an overview of electrochemical hydrogen storage. This review begins with an introducing to widely used energy storage systems, including battery and hydrogen storage technologies. Following that, multiple methods for synthesizing perovskite oxides are discussed. In addition, recent progress in perovskite-based compounds for electrochemical hydrogen storage, lithium-ion batteries, and sodium-ion batteries is comprehensively reviewed, with attention to their structural characteristics and electrochemical performance. In conclusion, the article examines emerging trends and opportunities for improving energy storage materials.</p>
