With the final system instruction confirmed, the domestic first iron-chromium liquid flow battery off-grid computing and power coordination demonstration project jointly developed by Zhonghai Energy Storage and Shishi Technology (Pinghu) Co., Ltd. (hereinafter referred to as Shishi Technology) has completed the full system commissioning and has officially entered the stable load operation stage. The successful implementation of this project marks a crucial commercial breakthrough for Zhonghai Energy Storage's iron-chromium liquid flow battery in the zero-carbon digital computing power sector, and opens up a new development path for domestic long-duration energy storage and the deep integration of computing and power in off-grid self-sustaining operation. 

In the 2026 National "Two Sessions", "computing and electricity collaboration" was first included in the "Government Work Report", clearly proposing the implementation of new infrastructure projects such as ultra-large-scale intelligent computing clusters and computing-electricity collaboration, to anchor the strategic direction for the green and low-carbon upgrade of the computing power industry and the integrated development of power generation, grid, load and storage. Following the top-level deployment of the country, China Ocean Energy Storage Technology Co., Ltd. and Shishi Technology Co., Ltd. jointly implemented a benchmark demonstration project in Luangao, Henan Province. With real-scene results, solid data and stable operation effectiveness, they presented an industrial answer to the implementation of computing-electricity collaboration innovation. 

The total project scale is designed to provide off-grid green electricity supply for 400kW computing units. The first phase includes 1MW photovoltaic power generation facilities in the park and a 2.5MW/15MWh iron-chromium liquid flow battery energy storage system that has been evaluated by the China Chemical Society as reaching international leading levels. It focuses on five core dimensions: precise prediction, active support, rapid response, intelligent scheduling, and energy consumption control. An integrated computing and electricity coordination management platform is established, successfully providing 7×24-hour uninterrupted green electricity for 150kW independent containerized computing units. This has fully verified the feasibility and reliability of long-term energy storage in a completely off-grid scenario, independently supporting the continuous, stable, and full-load operation of computing load. 

The project has established a fully closed-loop off-grid computing power supply system featuring "photovoltaic power generation + iron-chromium liquid flow long-duration energy storage + computing power load". The distributed photovoltaic power in the park serves as the primary clean energy source. The self-developed iron-chromium liquid flow battery of China Ocean Energy Storage takes on the role of long-duration energy buffering and voltage stabilization core carrier. Combined with the computing power-electricity integration solution and the intelligent control platform, it enables the coordinated scheduling of photovoltaic output, energy storage charging and discharging, and computing power load within milliseconds. It operates independently without relying on the municipal power grid, with 100% of computing power electricity supplied by clean energy. This effectively resolves the problems of computing power-electricity disconnection, poor coordination of source, grid, load, and storage, and the difficulty of local green electricity consumption. It forms a new operation mode where computing power and electricity mutually empower, dynamically match, and are efficiently utilized. 

Currently, the AI industry is experiencing rapid expansion, and the energy demand for computing facilities across the country is continuously surging. In remote areas such as mountainous regions, islands, the wild, and the western part of our country, there are numerous industry pain points including lagging power grid infrastructure, significant fluctuations in external power supply, high costs for expansion and investment, difficulties in local green power consumption, and high risks associated with backup power sources. Relying on traditional power sources such as mains electricity and diesel generators cannot meet the strict requirements of 7x24-hour continuous, highly reliable, and low-carbon operation for computing centers. 

After more than ten years of in-depth research on iron-chromium liquid flow battery technology, China Ocean Energy Storage has achieved full domestication of core materials, completed a complete set of technical breakthroughs in three core dimensions: electrode stack integration, multi-system coupling, and all-domain intelligent control, and has reached the international advanced level. As a key force in the domestic AI Infra (Artificial Intelligence Infrastructure) field, Shishi Technology has national-level engineering experience in computing power centers and has accumulated profound expertise in heterogeneous computing power scheduling and refined operation. This demonstration project fully validates the long-duration energy storage capacity of iron-chromium liquid flow batteries in the entire process without external network computing power scenarios, completely breaking the inherent development constraint that computing power construction must rely on municipal power grids, and opening up the "new energy power generation + iron-chromium liquid flow long-duration energy storage + computing power operation" commercialization implementation loop. It is targeted at weak power grids in regions such as western computing power hubs, mountainous edge computing stations, island intelligent computing centers, and remote data collection sites, and can output a complete set of autonomous, zero-carbon, long-term integrated energy supply computing network solutions. 

Relying on the core advantages of iron-chromium flow battery energy storage, such as strong safety, low cost, large scale, long lifespan, high efficiency, and wide application, China Ocean Energy Storage will continue to refine the integrated computing-electricity coordination technology system, optimize the system scheduling logic and operational efficiency, continuously expand the boundaries of integrated application of power generation, grid, load and storage, develop 168h+ ultra-long-duration energy storage scenarios, and create a replicable, implementable, and scalable energy supply system for renewable energy sources, power grids, loads and storage, to provide a mature industrial path for the new infrastructure of computing power in off-grid areas and weak power grids across the country, and green energy supply. This will help with the green and low-carbon transformation of national energy and the high-quality construction of digital new infrastructure, ensuring that constant green electricity reaches every corner of China.
