Xiamen, China — December 12, 2025 — At its third Eco-Day event, HiTHIUM launched the world’s first integrated lithium–sodium full-duration energy storage solution — the ∞Power Solutions for AI Data Centers (AIDC). The portfolio includes the ∞Power 6.25MWh 4h, ∞Power 6.9MWh 8h, ∞Power N2.28MWh 1h, and ∞Power 6.25MWh 2h systems. By combining long-duration lithium BESS with high-rate sodium-ion BESS, the solution establishes a coordinated “source-grid-load” energy support framework. It is designed to meet the core AIDC demands in sustainability, agility, stability, and cost efficiency, paving the way for low-carbon, highly resilient AI infrastructure.
Rising AI workloads are driving rapid growth in energy demand, while power infrastructure often requires 5–10 years to expand. AI data centers also experience frequent, sharp load fluctuations — sometimes up to 70% within tens of milliseconds — which pose risks to both grid stability and data center operations. Relying solely on traditional energy sources would further increase carbon emissions.
Dr. Nazar Yi, Board Member and Vice President of HiTHIUM, highlighted that overcoming this bottleneck calls for a new energy system characterized by agile deployment and green, low-carbon development. HiTHIUM’s new full-duration ∞Power Solutions for AI Data Centers represent a comprehensive upgrade, built on long-duration energy storage (LDES) at the source side and a coordinated lithium–sodium configuration at the load side.
By integrating long-duration storage with solar, wind, and other renewables, HiTHIUM’s solution shortens the construction cycle for power infrastructure to 1–2 years. When renewables supply over 80% of an AIDC’s energy needs, 8-hour LDES delivers maximum value — lowering the levelized cost of energy (LCOE), hedging against electricity price volatility, and supporting grid frequency regulation, black-start capability, and zero-carbon backup scenarios.
In addition to securing a steady green power supply, HiTHIUM introduces a second layer of protection at the grid and load side with its bi-directional stabilizer. The innovative combination of high-rate sodium-ion and long-duration lithium-ion storage creates an optimal balance of power and energy.
At the instantaneous response level, the high-rate sodium-ion system provides ultra-high discharge capability, smoothing load fluctuations within milliseconds and forming a dynamic “electromagnetic shield” for both the grid and the data center. HiTHIUM’s proprietary sodium-ion cells not only deliver exceptional performance but also offer a service life exceeding 25 years, boosting overall system efficiency by more than 3% and striking a balance between instant power response and long-term durability.
The lithium LDES backup system represents a major upgrade over traditional backup models. For a 4-hour backup duration, lifecycle costs are over 20% lower than those of diesel generators, enabling zero-carbon, silent backup power for AIDC campuses.
The solution can connect seamlessly to existing AIDC power architectures via fast-response PCS, and is also compatible with next-generation high-voltage DC systems through high-efficiency DC/DC conversion, achieving response times under 10 milliseconds.
With the launch of this full-duration portfolio, HiTHIUM has established a multi-layer, full-scenario smart energy security system that spans energy source, grid, and load. This system not only addresses current challenges in balancing computing growth with power availability, but also provides future-ready support that is green, agile, stable, and cost-effective for the AI era. Moving forward, HiTHIUM will continue to advance the integration of AI and energy, applying AI across R&D, manufacturing, and operations to accelerate the synergy between computing and power.
