A groundbreaking achievement in the field of energy storage has been accomplished with the successful grid connection of the world’s first in-situ solid-state battery large-scale energy storage project. The Zhejiang Longquan lithium-iron-phosphate (LFP) energy storage demonstration project, located in Zhejiang, China, completed its first test and connected to the grid on June 5th, 2024.
This momentous project combines semi-solid state batteries with an energy storage system, showcasing the potential for advanced battery technologies in enhancing the safety and security of power grids. Kehua, the company behind the project, utilized four high-performance energy storage converters, each with a capacity of 1.25MW, to achieve a grid-connected output of 35kV AC.
The innovative design of the project includes the parallel connection of the energy storage converters, enabling intelligent management of the charging and discharging processes. This automatic adjustment of the charging and discharging strategy significantly improves the overall safety and operational stability of the system. Customers have been impressed with the project’s excellent energy conversion efficiency, grid compatibility, and flexible system configuration capability.
With a storage capacity of 200,000 kWh, the project has the potential to discharge over 60 million kWh annually. This translates to significant carbon emissions reductions, saving approximately 23,000 tons of standard coal and reducing carbon dioxide emissions by about 72,000 tons. The energy storage solution plays a vital role in optimizing the local energy grid by managing peak demand and filling in valleys of electricity usage.
Kehua, a leading player in the power electronics industry, has amassed over 36 years of experience in delivering innovative solutions in the fields of photovoltaics, energy storage, microgrids, and integrated energy services. With a global PV installation exceeding 46GW and an energy storage installation exceeding 15.2GW/8.2GWh, Kehua has established itself as a trusted supplier and manufacturer. The company is committed to enabling a zero-carbon lifestyle by continually advancing clean energy technologies.
This momentous achievement in the energy storage sector not only demonstrates the potential of solid-state batteries but also highlights the important role they can play in revolutionizing grid-side energy storage. As the world continues to transition to a sustainable energy future, projects like the Zhejiang Longquan energy storage demonstration project pave the way for a more reliable, efficient, and environmentally friendly power grid.
