Solar, wind power generation system+ energy storage：
In September 2020, China announced a major pledge to the world: to strive for a peak in carbon dioxide emissions before 2030 and achieve carbon neutrality before 2060.
The development of renewable energy, primarily wind and solar power, is crucial to realizing these "dual carbon" goals. However, the power generation from these sources is subject to seasonal, meteorological, and geographical factors, resulting in significant randomness, intermittency, and instability. Consequently, integrating energy storage batteries is essential to store this electricity and ensure its efficient utilization.
The strong push for renewables has also spurred rapid growth in various energy storage technologies, such as pumped hydro storage, compressed air storage, lithium-ion batteries, and flow batteries. Among these, the vanadium redox flow battery (VRFB) has emerged as a highly suitable solution for industrial parks, owing to its long service life, high safety, flexible power and capacity design, and nearly 100% recyclability.
Key Advantages of VRFBs:
Safety: The aqueous electrolyte is non-flammable, and the system operates under ambient conditions, eliminating risks of fire or explosion.
Long Service Life: VRFBs can achieve a calendar life of over 30 years. Since the active material is vanadium on both sides, cross-contamination is prevented, allowing for unlimited charge-discharge cycles.
Design Flexibility: Power and energy ratings can be independently configured, offering significant design freedom.
Jutai's Competitive Edge in Vanadium Redox Flow Batteries (VRFB)
The vanadium electrolyte constitutes the primary cost driver for a Vanadium Redox Flow Battery (VRFB), accounting for over 53% of the total expense. Therefore, reducing the cost of this electrolyte is pivotal to enabling the widespread adoption of VRFB technology.
As a high-tech manufacturer dedicated to environmental protection and the R&D of functional new materials, Jutai holds a distinct advantage: it does not rely on conventional vanadium mines. Instead, the company leverages advanced technology to efficiently extract vanadium resources from industrial waste, producing 5,000 tons of vanadium pentoxide (V₂O₅) annually. This key precursor material for VRFBs places Jutai among the top five domestic suppliers in China.
Furthermore, Jutai strategically entered the VRFB sector five years ago. Through deep collaboration with leading academic institutions such as Xi'an Jiaotong University and Southwest Jiaotong University, the company has mastered the core technology for manufacturing the critical electrolyte and essential processes for the battery stack.
Concurrently, Jutai has established the capability to set up integrated production lines for the manufacturing and assembly of complete VRFB systems.
The Vanadium Redox Flow Battery (VRFB) and Its Principle：
The Vanadium Redox Flow Battery (VRFB) operates by using an external pump to push electrolytes, which contain different valence state vanadium ions in sulfuric acid, into the positive and negative electrodes of the cell stack. Under physical force, these electrolytes circulate in a closed-loop between storage tanks and the cell stack, charging and discharging through the movement of electrons between the electrodes.
The primary ingredient of its electrolyte is high-purity vanadium pentoxide, which is one of Jutai's main products. Building on the current foundation of electrolyte material production, Jutai is in discussions with various parties to establish its own energy storage battery equipment production line.
