At the Jingneng exhibition area, the 1.2KW all vanadium flow battery system developed by Jingtai Power, a subsidiary of Jingneng Electric Power, has aroused strong interest among visitors. This luggage like energy storage device, with its "Beijing Energy Solution," addresses the pain points of new energy grid connection and has become an innovative tool to solve industry problems. As a key supporting technology for the new power system, it can convert unstable wind and photovoltaic power into stable and reliable electrical energy. "The on-site technicians introduced that this technology has increased the current efficiency to 94.98% and the energy efficiency to 68.26%, both of which are at the leading level in the industry.

At present, Jingneng Group has completed the research and development of commercial grade vanadium liquid flow energy storage system products and has achieved grid connected trial operation. This breakthrough not only marks significant progress for Beijing Energy Group in the field of long-term energy storage, but also provides key technical support for the green transformation of thermal power enterprises.

Since the introduction of the "dual carbon" target, Jingneng Group has demonstrated significant innovation capabilities and strategic layout in the field of flow battery technology research and industrial application. Its core progress focuses on the independent research and development and large-scale implementation of all vanadium flow batteries.

The experimental team adopts an integrated mode of "production, learning, research, and application" to break through the bottleneck of traditional sealing technology. By optimizing the flow channel design, flow rate control, and mass transfer uniformity of the fuel cell stack, they have achieved a leap from individual cells to composite fuel cells.

By March 2025, Jingneng Power will further complete the research and development of a 40kW level fuel cell system and connect it to the plant power grid, with an energy efficiency increase of 71.70%, verifying its technological advantages in long-term energy storage scenarios, including intrinsic safety, over 25000 cycle life, and power capacity module decoupling characteristics, becoming a key technical support for the green transformation of thermal power. In addition, Jingneng Group has also made breakthroughs in patent layout. Its high-power vanadium flow battery stack adopts laser embedded welding technology, which solves the risk of multi component assembly leakage and significantly improves production standardization level, laying the foundation for future GW level capacity expansion.

The deep integration of academia and industry further accelerates technological iteration. Beijing Energy Group, Southeast University, Zhejiang University and other universities jointly accepted the 40kW level stack project, while Dalian Rongke's long-term cooperation with the Chinese Academy of Sciences Dalian Institute of Chemical Physics has laid a technical barrier to its stack design and electrolyte preparation.

At present, capital not only focuses on technological maturity, but also emphasizes the feasibility of commercial scenarios and the potential for global layout.

The resonance between policy orientation and market demand drives the upward trend of liquid flow battery stations.

In the new energy storage demonstration projects of the National Energy Administration in 2024, flow batteries account for a significant proportion, and the 8 demonstration projects participated by Beijing Energy Group cover both the grid side and the power supply side. The valuation logic of the capital market has been restructured accordingly, with state-owned assets and industrial capital becoming the main drivers. The average annual growth rate of project valuations has exceeded 30%, reflecting the industry's transition from the technology verification period to the large-scale production period. It is predicted that by 2030, the market share of all vanadium flow batteries in long-term energy storage will exceed 15%, with an installed capacity of 50GW. This prospect will attract more cross-border players, such as pesticide leader Haili Group entering the upstream of the industry chain through the acquisition of vanadium mining exploration rights, and building vertical integration capabilities from resource extraction to system integration.

In this process, state-owned enterprises such as Beijing Energy Group are gradually transforming from technology followers to industry standard setters, relying on their resource coordination and project implementation capabilities. The grid connected operation of their 40kW level fuel cell not only provides samples for internal energy storage and peak shaving within the group, but also contributes to the construction of the "Beijing Energy Solution" for the new power system.

Looking ahead to the future, Beijing Energy Group plans to deepen the penetration of vanadium batteries in zero carbon communities, integrated photovoltaic storage and charging, and other scenarios through a three-step strategy of "efficient configuration design, large-scale application, and independent core technology" in collaboration with industry chain partners. At the capital level, the activity of Pre IPO round financing has increased, and companies such as Dalian Rongke have started listing guidance. It is expected that 3-5 liquid flow battery companies will be listed on the Science and Technology Innovation Board around 2026.

With the iteration of Beijing Energy Group's 40kW level technology towards the 100kW level and the continuous influx of cross-border capital, flow batteries are expected to replicate the path of the lithium battery industry, moving from demonstration projects to affordable applications, and ultimately becoming the cornerstone technology for building a new type of power system.
