Jiang Weiliang of Yongtai Digital Energy: "The 2025 Energy Storage Tri-Polar Battle"

(Shenzhen, February 27, 2025) – At the 2025 International New Energy Industry Marketing Summit*, the keynote speech titled "New Trends and Opportunities in China's Lithium Battery Energy Storage Industry" by Mr. Jiang Weiliang, Senior Vice President of Yongtai Digital Energy, was a wake-up call for the global energy storage sector, providing a clear vision for its development. With over two decades of experience in the power and energy sector, this industry veteran used comprehensive data and sharp insights to highlight the strategic opportunities and evolutionary logic of energy storage under the "dual-carbon" strategy.

I. Multi-Dimensional Support in a Strategic Opportunity Period

"When lithium carbonate prices stabilize at 80,000 RMB per ton, and the cost of a two-hour energy storage system falls below 0.5 RMB/Wh, we must take a broader historical perspective to evaluate this industry." Jiang opened with this statement, emphasizing that despite current challenges such as overcapacity and price competition, the fundamental judgment that energy storage remains in a strategic opportunity period has not changed.

From a policy perspective, the "dual-carbon" goal has transitioned from a national commitment to institutional practice. The 2024 "National Unified Electricity Market Development Plan Bluebook" released by the National Energy Administration outlines a three-step market reform, targeting a unified electricity market by 2029—reshaping the fundamental value logic of energy storage. "The experience of mature electricity markets in Germany and the U.S. shows that every step forward in market mechanisms unlocks a new layer of energy storage value," Jiang stressed.

Technological and economic breakthroughs are another crucial driver. By 2024, the global installed energy storage capacity exceeded 300GWh—a staggering 3,000-fold increase over a decade. China leads with a 60% market share, and storage costs have dropped by 47% compared to 2020, bringing the cost per kWh close to coal power parity. This exponential technological advancement is pushing energy storage from "policy-driven" to "market-driven."

II. Industry Restructuring Amid Globalization

"Expand overseas, or be eliminated"—this statement resonated with the audience. Citing BloombergNEF's forecasts, Jiang noted that the global energy storage market is expected to grow at a compound annual rate of 28% over the next decade, with emerging markets becoming the new growth engines. In 2024 alone, the Middle East signed over 20GWh of storage projects, energy storage solutions in Africa saw a 300% increase in orders, and South America’s demand surged exponentially.

This wave of globalization is reshaping industry dynamics. Yongtai Digital Energy's 600kW liquid-cooled ultra-fast charging demonstration station in Longhua Industrial Park exemplifies China's technological exports. "Chinese energy storage enterprises are evolving from selling products to selling systems, moving beyond mere exports toward exporting standards," Jiang pointed out. However, challenges such as overseas factory deployment timing, geopolitical risks, and securing international orders require strategic foresight.

III. A Crossroads in Technological Revolution

From a technological standpoint, the industry faces critical choices. While lithium batteries still dominate with a 90% market share, technological iterations are accelerating. The rapid replacement of 280Ah cells by 314Ah models and the push for 500Ah+ ultra-large capacity cells signal imminent breakthroughs in energy density. "The commercialization of semi-solid-state batteries in electric vehicles is laying the technical groundwork for energy storage applications," Jiang emphasized.

Meanwhile, technological diversification is gaining momentum. Vanadium flow batteries are emerging in long-duration storage, sodium-ion battery commercialization is progressing, and grid-forming PCS technology is addressing challenges in integrating high proportions of renewable energy. These innovations are not simple substitutes but integral components of a multi-dimensional technological matrix.

IV. Breaking Market Barriers

Jiang addressed the widely criticized "built but not operational" phenomenon by proposing market-driven solutions. The revenue model for independent energy storage plants is becoming clearer: 45% from arbitrage in the electricity spot market, 30% from ancillary services, and the remaining balance covered by capacity pricing incentives. This structure is supported by expanded spot market trials and improved ancillary service regulations.

The explosive growth of industrial and commercial energy storage further validates market mechanisms. The Yangtze River Delta and Pearl River Delta regions, leveraging peak-valley price differences exceeding 0.7 RMB/kWh, have established mature business models. Meanwhile, advancements in virtual power plant technology are enhancing the value of aggregated distributed storage. "When the cost per stored kWh falls below peak electricity prices, the market will make its choice," Jiang asserted.

V. The Perennial Challenge of Safety and Efficiency

Despite the industry's rapid progress, Jiang issued a strong warning about safety risks, citing recent energy storage accidents in the U.S. and U.K. "Safety is the '1' in front of all other zeros," he cautioned. Yongtai Digital Energy showcased a six-layer safety protection system—from intelligent early warning and explosion-proof designs to active fire suppression and flame-retardant materials—demonstrating evolving industry safety standards. AI-driven safety monitoring, trained on full-lifecycle data, is shifting accident prevention from reactive response to proactive prediction.

VI. The Future of Scenario-Based Solutions

"Energy storage is not the endpoint but the connector in the energy revolution," Jiang concluded, unveiling scenario-based solutions that expand the industry's scope. Yongtai Digital Energy's "Energy Storage + X" model has spawned over 20 solutions, including integrated solar-storage-charging-inspection hubs, port microgrids, and backup power for data centers. This deep user-driven innovation is transforming energy storage providers into comprehensive energy service ecosystems.

In Shenzhen’s Yantian Port, the "solar + storage + shore power" system has achieved zero emissions during vessel docking. Meanwhile, in Xiong’an New Area’s digital industry park, energy storage coupled with waste heat recovery has raised overall energy efficiency to 85%. These case studies highlight a shift from single-use peak-shaving and frequency regulation toward integrated energy services.
