Dalian, China-based vanadium flow battery (VFB) developer Rongke Power, has completed a 175MW/700MWh project, which they are calling the world’s largest vanadium flow battery project. Located in Ushi, China, the project will provide various services to the grid, including grid forming, peak shaving, frequency regulation and renewable integration.
It is considered to be one of the most promising energy storage technologies. Rongke Power has over 450 patents in vanadium flow battery technology, saying their flow battery systems are operational in key regions globally.
A press release by the company states that the vanadium flow battery project has the ability to store and release 700MWh of energy. This system ensures extended energy storage capabilities for various applications. It is designed with scalability in mind, and is poised to support evolving energy demands with unmatched performance.
Vanadium flow batteries provide continuous energy storage for up to 10+ hours, ideal for balancing renewable energy supply and demand. As per the company, they are highly recyclable and adaptable, and can support projects of all sizes, from utility-scale to commercial applications.
According to research published in 2021 in Advances in Smart Grid Power Systems, compared with other chemical energy storage technology, the vanadium redox flow battery has advantages in safety, longevity and environmental protection. It is considered to be one of the most promising energy storage technologies.
Rongke Power has over 450 patents in vanadium flow battery technology, saying their flow battery systems are operational in key regions globally. Earlier this yea in August, the company announced a VFP gigafactory equipped with fully automated, robotic systems, designed to produce up to 1GW in battery energy storage systems (BESS) annually.

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;. . 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. . 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,. . 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 and diversified. We envision that each region will cover over 90 percent of local. [pdf]
Stationary storage will also increase battery demand, accounting for about 400 GWh in STEPS and 500 GWh in APS in 2030, which is about 12% of EV battery demand in the same year in both the STEPS and the APS. IEA. Licence: CC BY 4.0 Battery production has been ramping up quickly in the past few years to keep pace with increasing demand.
The contribution of different EV segments to electricity demand varies by region. For example, in 2023 in China, electric 2/3Ws and buses combined accounted for almost 30% of EV electricity demand, while in the United States, electric cars represented over 95% of EV electricity demand.

Batteries for mobility applications, such as electric vehicles (EVs), will account for the vast bulk of demand in 2030—about 4,300 GWh; an unsurprising trend seeing that mobility is growing rapidly. This is largely driven by three major drivers:
Automotive lithium-ion (Li-ion) battery demand increased by about 65% to 550 GWh in 2022, from about 330 GWh in 2021, primarily as a result of growth in electric passenger car sales, with new registrations increasing by 55% in 2022 relative to 2021.
As EV sales continue to increase in today’s major markets in China, Europe and the United States, as well as expanding across more countries, demand for EV batteries is also set to grow quickly. In the STEPS, EV battery demand grows four-and-a-half times by 2030, and almost seven times by 2035 compared to 2023.
To generate revenue from battery energy storage systems in Europe, companies need to be strategic and take advantage of different markets and services. Capacity markets, for example, offer a stable source of income: payment is made for the provision of reserve capacity.
