Though pumped hydro currently dominates global storage capacity, electrochemical is growing the fastest. Generally, pumped hydro storage is used for longer-term storage compared to battery storage, which is often used on a day-to-day scale. Both distributed and centralized storage can be system integrated or standalone. However, centralized storage. Lithium-Ion Battery Materials and Supply1. Human rights challenges(e.g., child labor, slavery) 2. Environmental impacts(e.g, water, land, and air pollution, heavy metal leakage, habitat loss) 3. Human health problems(e.g., lung and cardiovascular problems, birth defects) (See our Energy, the Environment, and Justicepage for more information.)Cost RangeUtility scale storage is much cheaper than residential scale.
