Longer-duration storage, safety-driven procurement and FEOC compliance are starting to push alternative chemistries closer to scale. . MITEI's three-year Future of Energy Storage study explored the role that energy storage can play in fighting climate change and in the global adoption of clean energy grids. Despite policy changes and uncertainty in the world's two largest markets, the US and China, the sector continues to grow as developers push forward with larger and larger utility-scale projects. Since 2024. . Advances in solid-state, sodium-ion, and flow batteries promise higher energy densities, faster charging, and longer lifespans, enabling electric vehicles to travel farther, microgrids to operate efficiently, and renewable energy to integrate seamlessly into the grid. While lithium-ion remains dominant, pressure is building for. . With renewable energy on the rise, investments in storage technologies have surged, reaching $54 billion worldwide in 2024.
