Europe and China are leading the installation of new pumped storage capacity – fuelled by the motion of water. Batteries are now being built at grid-scale in countries including the US, Australia and Germany. Thermal energy storage is predicted to triple in size by 2030. Mechanical energy storage harnesses motion or gravity to store electricity.
Energy Storage Technologies; Recent Advances, Challenges, and
The implementation, operation, and replacement of energy storage technologies also require a large amount of capital. Certain energy storage devices may cause environmental impact, which starts from the extraction of materials used for manufacturing and continues until the end of their useful life until disposal.

Intermittency and periodicity in net-zero renewable energy
The characteristics of the different periods of energy deficit, coupled with the economics of energy storage technologies, mean that several different types of storage are likely to be required. Electrochemical energy storage systems have high efficiency and low power costs but high volume costs.
Solar Integration: Solar Energy and Storage Basics
Although using energy storage is never 100% efficient—some energy is always lost in converting energy and retrieving it—storage allows the flexible use of energy at different times from when it was generated. However, it requires suitable landscapes and reservoirs, which may be natural lakes or man-made by constructing dams, requiring
Hydrogen Storage
Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C.
