Leveraging its dominant position in electric vehicles, lithium batteries and solar panel manufacturing, China is now strategically positioned to tap into new-type energy storage as a key driver of economic expansion and energy security, said industry experts and company executives.

New-type energy storage, such as electrochemical energy storage and hydrogen storage, is poised to drive China's broader energy system transformation, alongside economic benefits, powering the nation's economic engine and ushering in an era of unprecedented energy independence and sustainability, they said.

The year 2024 witnessed an unprecedented surge in China's new energy storage sector, a dynamic expansion that redefines the nation's power grid and accelerates its ambitious carbon neutrality goals.

According to the "Energy Storage Industry Research White Paper 2025" released during the recently concluded 13th Energy Storage International Conference and Expo held in Beijing, the new-type energy storage sector has sustained high-speed growth throughout the 14th Five-Year Plan (2021-25) period.

Looking ahead to 2025, the report anticipates newly installed new energy storage projects in China would exceed 30 gigawatts, further solidifying the nation's global leadership in the sector.

Crucially, the white paper highlighted a transformative shift in the sector's development model, predicting that new energy storage would transition from pilot demonstrations to large-scale commercial applications, ushering in a golden era of rapid expansion driven by market forces.

Newly commissioned new energy storage projects in 2024 reached an impressive scale of 43.7 GW, representing a year-on-year growth rate of 103 percent and accounting for 59 percent of global market share, demonstrating China's dominant position in the global energy storage landscape.

Notably, annual newly commissioned installed capacity surpassed the cumulative installed capacity of all previous years for the third consecutive year, signifying a paradigm shift in China's energy storage portfolio.

With the performance of lithium batteries significantly improving over the past few years and the iteration of multiple technology routes accelerating, the energy storage industry has achieved scaled development, said Chen Haisheng, chairman of China Energy Storage Alliance.

The number of newly added enterprises has reached a record high, while industry capacity keeps increasing and prices also decreasing, he said.

Chen emphasized that China's primary energy storage technologies are now largely on par with the most advanced global levels, with lithium batteries, compressed air energy storage and flow batteries achieving international leadership positions.

According to the alliance, China's installed capacity of new-type energy storage exceeded that of pumped storage for the first time at the end of 2024, while new-type energy storage has also been highlighted in many regional industrial plans, and its value target for 2025 has exceeded 3 trillion yuan ($415.6 billion).

The National Energy Administration said newly installed capacity of new-type energy storage experienced explosive growth last year surpassing 70 million kilowatts and is poised to become a cornerstone of the global energy transition.

The cumulative operational capacity across China rose 130 percent year-on-year, with the average energy storage duration extended to 2.3 hours, up 0.2 hours from the 2023 figure, enhancing grid stability and renewable energy integration, it said.

The momentum from 2024 surged into the new year, with regions across China accelerating the development of new energy storage projects. Construction sites buzzed with activity as provinces vied to expand their storage capacities, recognizing the strategic importance of this burgeoning sector.
