2.8GWh! NARADA Power Secures World's Largest Semi-Solid-State Battery Energy Storage Project

2025-08-14 | Eric

Recently, NARADA Power successfully signed energy storage project contracts totaling 2.8GWh, all of which will utilize the company's self-developed 314Ah semi-solid-state energy storage batteries. This marks the world's largest semi-solid-state battery energy storage project to date, representing a critical milestone in the commercial application of solid-state energy storage battery technology.

Three Major Projects in the Greater Bay Area: Independent Energy Storage Supports Grid Resilience

The contracted projects consist of three independent energy storage systems with a total capacity of 2.8GWh. Among them, the Shenzhen project has a scale of 1.2GWh, while Shanwei hosts two projects, each with 800MWh capacity.

Upon completion, these projects are expected to absorb over 1 billion kWh of renewable energy annually, significantly enhancing the regional grid's capacity to integrate renewable energy. This will effectively alleviate power supply-demand imbalances in the Guangdong-Hong Kong-Macao Greater Bay Area while reducing CO2 emissions by approximately 1 million tons per year.

This achievement represents a major breakthrough in NARADA's "energy storage technology + application scenario" strategy. As a megacity, Shenzhen demands energy storage systems with exceptional safety and cycle life requirements, while Shanwei's offshore wind power resources require energy storage to stabilize grid operations. NARADA's semi-solid-state battery energy storage system perfectly addresses the core needs of both scenarios.

Semi-Solid-State Batteries Solve Safety and Cost Challenges

The technological cornerstone of this mega energy storage project is NARADA's self-developed 314Ah semi-solid-state energy storage battery. Through two key innovations—"oxide solid-liquid hybrid technology" and "high-melting-point polymer separator"—the battery achieves significant improvements in both safety and performance. NARADA's R&D team has overcome critical challenges in solid-state electrolytes and interface wetting agents.

The 314Ah semi-solid-state battery innovatively employs an oxide-based solid-liquid hybrid electrolyte system, which effectively suppresses lithium dendrite growth, reduces thermal runaway risks, while maintaining excellent ionic conductivity—providing dual assurance for long cycle life and high safety.

Solid-State Battery Commercialization Accelerates

This project represents the first global gigawatt-hour-scale commercial application of solid-state battery technology in energy storage.

The contract signing demonstrates industry recognition of NARADA's solid-state technology and engineering capabilities, while also providing operational data support for the company's future expansion into data center energy storage and commercial/industrial energy storage applications.

Solid-state battery technology addresses the core requirements of large-scale energy storage for "ultra-high safety" and "long-term reliability." For the entire industry, large-scale commercialization will accelerate the maturity of the solid-state battery supply chain and cost reduction, injecting strong momentum for technological advancement.

NARADA has consistently pursued a "develop one generation, reserve one generation" technology strategy, maintaining continuous investment in cutting-edge research. The company began solid-state battery R&D in 2017, making it one of China's earliest entrants in this field.

In late 2024, NARADA's Zhejiang Provincial Key R&D Program passed acceptance review, having successfully developed 30Ah all-solid-state batteries that solved "solid-solid interface" challenges, significantly improving cycle life and rate performance.

In April 2025, NARADA launched its groundbreaking 783Ah ultra-large-capacity solid-state energy storage battery. Through three core technological breakthroughs—"flexible biphasic oxide solid electrolyte," "multilayer heterogeneous composite structure design," and "in-situ electrolyte film formation"—the company achieved revolutionary improvements in both energy density and safety performance.

Building on its long-term technological accumulation, NARADA will continue advancing research in oxide and sulfide solid-state batteries, driving the energy storage industry's transformation toward becoming the "value center" of new energy applications through technological innovation.
