The main driver is the increasing need for system flexibility and storage around the world to fully utilise and integrate larger shares of variable renewable energy (VRE) into power systems. IEA. Licence: CC BY 4.0 Utility-scale batteries are expected to account for the majority of storage growth worldwide.
Storage enables electricity systems to remain in balance despite variations in wind and solar availability, allowing for cost-effective deep decarbonization while maintaining reliability. The Future of Energy Storage report is an essential analysis of this key component in decarbonizing our energy infrastructure and combating climate change.
Today, worldwide installed and operational storage power capacity is approximately 173.7 GW (ref. 2). Short-duration storage — up to 10 hours of discharge duration at rated power before the energy capacity is depleted — accounts for approximately 93% of that storage power capacity 2.
In optimizing an energy system where LDES technology functions as “an economically attractive contributor to a lower-cost, carbon-free grid,” says Jenkins, the researchers found that the parameter that matters the most is energy storage capacity cost.
Exploring different scenarios and variables in the storage design space, researchers find the parameter combinations for innovative, low-cost long-duration energy storage to potentially make a large impact in a more affordable and reliable energy transition.
Global installed storage capacity is forecast to expand by 56% in the next five years to reach over 270 GW by 2026.

Global electricity demand is set to more than double by mid-century, relative to 2020 levels. With renewable sources – particularly wind and solar – expected to account for the largest share of power output in the coming decades, energy storage will play a significant role in maintaining the balance between supply and demand.

In the electricity sector, governments should consider energy storage, alongside other flexibility options such as demand response, power plant retrofits, or smart grids, as part of their long-term strategic plans, aligned with wind and solar PV capacity as well as grid capacity expansion plans.

Mechanical energy storage Mechanical energy storage harnesses motion or gravity to store electricity. For example, a flywheel is a rotating mechanical device that is used to store rotational energy that can be called up instantaneously.

Global demand for Li-ion batteries is expected to soar over the next decade, with the number of GWh required increasing from about 700 GWh in 2022 to around 4.7 TWh by 2030 (Exhibit 1). Batteries for mobility applications, such as electric vehicles (EVs), will account for the vast bulk of demand in 2030—about 4,300 GWh; an. . The global battery value chain, like others within industrial manufacturing, faces significant environmental, social, and governance (ESG). . Some recent advances in battery technologies include increased cell energy density, new active material chemistries such as solid-state batteries, and cell and packaging production technologies, including electrode dry. . Battery manufacturers may find new opportunities in recycling as the market matures. Companies could create a closed-loop, domestic supply chain that involves the collection, recycling, reuse, or repair of used Li-ion. . The 2030 Outlook for the battery value chain depends on three interdependent elements (Exhibit 12): 1. Supply-chain resilience. A resilient battery value chain is one that is regionalized. [pdf]
Global energy storage’s record additions in 2022 will be followed by a 23% compound annual growth rate to 2030, with annual additions reaching 88GW/278GWh, or 5.3 times expected 2022 gigawatt installations. China overtakes the US as the largest energy storage market in megawatt terms by 2030.
Battery energy storage systems (BESS) will have a CAGR of 30 percent, and the GWh required to power these applications in 2030 will be comparable to the GWh needed for all applications today. China could account for 45 percent of total Li-ion demand in 2025 and 40 percent in 2030—most battery-chain segments are already mature in that country.
Short-term energy storage demand is typically defined as a typical 4-hour storage system, referring to the ability of a storage system to operate at a capacity where the maximum power delivered from that storage over time can be maintained for 4 hours.
Renewable penetration and state policies supporting energy storage growth Grid-scale storage continues to dominate the US market, with ERCOT and CAISO making up nearly half of all grid-scale installations over the next five years.

With renewable sources – particularly wind and solar – expected to account for the largest share of power output in the coming decades, energy storage will play a significant role in maintaining the balance between supply and demand.
The Americas region represents 21% of annual energy storage capacity on a gigawatt basis by 2030. The US is by far the largest market, led by a pipeline of large-scale projects in California, the Southwest and Texas. The US has a seen a wave of project delays due to rising battery costs.
