The difficulties of high costs, performance limits, safety issues, environmental concerns, and regulatory uncertainties present formidable obstacles in the energy storage industry. This review discusses the role of energy storage in the energy transition and the blue economy, focusing on technological development, challenges, and. . The transition to a sustainable energy future depends on innovative energy storage technologies that promise efficiency, scalability, and environmental compatibility. However, despite their potential, these solutions face significant challenges that must be addressed to achieve widespread adoption. . By storing energy during off-peak hours and using it during peak demand, businesses can reduce their reliance on the grid and potentially reduce costs. The reasons why it is difficult to store energy and why it is usually consumed immediately when generated are complex and multifaceted. Energy storage systems play a pivotal role in balancing supply and demand, smoothing the intermittency of renewable energy sources, and. .
