Shanghai Electric Energy Storage Technology Co., Ltd. announced the completion of the factory acceptance test for its vanadium redox flow battery equipment, for delivery to Zaragoza, Spain, for a commercial energy storage project, marking the first time that Shanghai Electric delivers its flow battery products to a European partner in bulk.
Under the agreement with local partner in Spain, which is the sixth sub-contract that Shanghai Electric signed with the Spain-based energy storage solution provider, Shanghai Electric Energy Storage will supply bespoke VRFB products for the local renewable projects. The cooperation of the pair showcases the market adaptability of Shanghai Electric's flow battery solutions as well as its ability to deliver products tail-made to help European countries accelerate toward energy transition.
Meanwhile, Shanghai Electric and local partners are also in discussion on the design of multiple system projects, which encompass the supply of standard containerized systems and products. The two companies are also planning to cooperate on the construction of MW-scale projects.
Energy storage technology is one of the foundations for the renewable energy revolution, playing a key role in facilitating the world's achievement of low-carbon targets. Shanghai Electric, with its long-term track record in new energy technology development, is a pioneer that pushes the boundary of battery solutions, spearheading innovation for VRFB products to boost the reliability, sustainability, and affordability of renewable power sources.
In 2023, Shanghai Electric made a significant breakthrough in the field of battery storage technology with the launch of the 500kW/3000kWh energy storage system, a new solution that represents a major milestone in the development of vanadium redox flow battery (VRFB) technology. By upgrading the form factor, functionality, and performance of VRFBs, Shanghai Electric has opened up new possibilities for renewable energy storage, empowering China and beyond to reduce dependence on fossil fuels and contributing to a cleaner, more sustainable future.
The system employs a 65 kW high-power, high-performance stack, which is the largest single stack developed by China's homegrown energy company. The 500 kW battery features 4s2p configurations, making it the largest single module among long-duration flow batteries in China. The system's DC-side efficiency exceeds 85%, with the overall energy efficiency reaching 90%, trimming the cost of electricity per kWh down to RMB 0.2 (USD 0.028).
With its electrolyte consisting of water and inorganic salts, the system is capable of operating at normal temperature and pressure without the risk of flammable or explosive hazards, offering 20,000 charge and discharge cycles with no capacity attenuation in its lifespan.
It is designed as a high-power, long-duration energy storage system for wind energy and solar PV projects, with its expandable structure helping save 50% of land usage. The module is easily transportable, quick to install and deploy, and suitable for locations with a temperature range of -30 to 60 degrees Celsius and harsh environmental conditions.
