Energy storage is a potential substitute for, or complement to, almost every aspect of a power system, including generation, transmission, and demand flexibility. Storage should be co-optimized with clean generation, transmission systems, and strategies to reward consumers for making their electricity use more flexible. . Goals that aim for zero emissions are more complex and expensive than NetZero goals that use negative emissions technologies to achieve a reduction of 100%. The pursuit of a zero, rather than net-zero, goal for the. . The need to co-optimize storage with other elements of the electricity system, coupled with uncertain climate change impacts on demand and supply, necessitate advances in analytical tools to reliably and efficiently plan, operate, and. . The intermittency of wind and solar generation and the goal of decarbonizing other sectors through electrification increase the benefit of. . Lithium-ion batteries are being widely deployed in vehicles, consumer electronics, and more recently, in electricity storage systems. These batteries have, and will likely continue to have, relatively high costs. [pdf]
Making energy storage systems mainstream in the developing world will be a game changer. Deploying battery energy storage systems will provide more comprehensive access to electricity while enabling much greater use of renewable energy, ultimately helping the world meet its Net Zero decarbonization targets.
Energy storage technologies are also the key to lowering energy costs and integrating more renewable power into our grids, fast. If we can get this right, we can hold on to ever-rising quantities of renewable energy we are already harnessing – from our skies, our seas, and the earth itself.
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.
To meet ambitious global decarbonization goals, electricity system planning and operations will change fundamentally. With increasing reliance on variable renewable energy resources, energy storage is likely to play a critical accompanying role to help balance generation and consumption patterns.
The need to co-optimize storage with other elements of the electricity system, coupled with uncertain climate change impacts on demand and supply, necessitate advances in analytical tools to reliably and efficiently plan, operate, and regulate power systems of the future.
Other similar technologies include the use of excess energy to compress and store air, then release it to turn generator turbines. Alternatively, there are electrochemical technologies, such as vanadium flow batteries.

China's energy storage battery exports have been growing significantly. In 2021, China exported 3.427 billion lithium-ion batteries, with an export value of US$28.423 billion. From January to October 2022, China exported 3.195 billion lithium-ion batteries, with an export value of US$39.754 billion1. In the first five months of 2024, China's cumulative export volume of energy storage batteries reached 8.4 GWh, a year-on-year increase of 50.1%2. From January to August 2022, China's cumulative exports of lithium-ion energy storage batteries surged by 83% year-over-year3. [pdf]
Cushman & Wakefield has released its China Battery Energy Storage System (BESS) Market – New Energy for a New Era report. A Battery Energy Storage System (BESS) secures electrical energy from renewable and non-renewable sources and collects and saves it in rechargeable batteries for use at a later date.
“China’s lithium battery exports rose by 27.8 per cent in one year and reached USD $65 billion and the US are currently the main importer of Chinese lithium batteries. “Prices for solar panels have fallen considerably in one year causing a decline in the monetary value of exports raising concern for oversupply issues.
Figure 2: Cumulative installed capacity of new energy storage projects commissioned in China (as of the end of June 2023) In the first half of 2023, China's new energy storage continued to develop at a high speed, with 850 projects (including planning, under construction and commissioned projects), more than twice that of the same period last year.
A Battery Energy Storage System (BESS) secures electrical energy from renewable and non-renewable sources and collects and saves it in rechargeable batteries for use at a later date. When energy is needed, it is released from the BESS to power demand to lessen any disparity between energy demand and energy generation.
China has created an energy storage ecosystem with players throughout the supply chain. The upstream players are mainly battery and raw materials manufacturers, with many benefitting from first-mover advantage. Chinese manufacturers have gained a substantial market in this domain.
Localities have reiterated the central government’s goal of developing an integrated format of “new energy + storage” (such as “solar + storage”), with a required energy storage allocation rate of between 10% and 20%. China has created an energy storage ecosystem with players throughout the supply chain.
