XIAMEN, China, Dec. 12, 2025 — At its third Eco-Day event, HiTHIUM unveiled ∞Power globally, calling it the world’s first collaborative lithium‑sodium full‑duration energy storage portfolio designed specifically for AI Data Center (AIDC). The portfolio combines long‑duration lithium BESS with high‑rate sodium‑ion BESS, featuring models such as ∞Power 6.25MWh 4h, ∞Power 6.9MWh 8h, ∞Power N2.28MWh 1h, and ∞Power 6.25MWh 2h. This integrated solution creates a coordinated “source‑grid‑load” framework to meet key AIDC needs in sustainability, agility, stability, and cost‑efficiency—potentially setting a new benchmark for low‑carbon, resilient AI infrastructure.

Long‑Duration Storage Recognized as Critical for AI Power Demands

Analysts point out that rising AI computational workloads are driving unprecedented energy demand, while traditional power infrastructure development trails by 5–10 years. Moreover, AIDCs produce rapid, sharp load fluctuations—sometimes up to 70% within milliseconds—which threaten both grid stability and data center uptime. Conventional energy sources further aggravate carbon emissions.

Dr. Nazar Yi, HiTHIUM Board Member and Vice President, stressed that overcoming this bottleneck requires an energy system focused on agile deployment and green development. The new ∞Power Solutions are said to offer a comprehensive upgrade, utilizing long‑duration energy storage (LDES) on the source side and a lithium‑sodium collaborative configuration on the load side.

A “Green Power Accelerator” for Source‑Side Agility

By coupling LDES with renewables such as solar and wind, HiTHIUM’s approach aims to shorten power infrastructure build cycles to 1–2 years. In cases where renewables supply more than 80% of an AIDC’s demand, the 8‑hour LDES is designed to maximize value—reducing the levelized cost of energy (LCOE), mitigating price volatility, and supporting grid services like frequency regulation and black‑start capabilities.

A Bidirectional Stabilizer for Grid and Load‑Side Resilience

Beyond securing a steady green power supply, HiTHIUM adds a resilience layer at the grid and load side with a bidirectional stabilizer. The key innovation lies in pairing high‑rate sodium‑ion batteries for instantaneous power with long‑duration lithium‑ion systems for energy capacity.

For instantaneous response, the high‑rate sodium‑ion system delivers ultra‑high discharge capability to smooth millisecond‑level load spikes—forming what the company describes as a dynamic “electromagnetic shield” for both the grid and the data center. HiTHIUM’s proprietary sodium‑ion cells are reported to offer over 25 years of service life, improving system efficiency by more than 3% while balancing instant power response with long‑term durability.

The lithium LDES backup system is presented as a major upgrade over traditional models. For a 4‑hour backup duration, lifecycle costs are said to be over 20% lower than those of diesel generators, enabling zero‑carbon, silent backup power for AIDC campuses.

The solution can integrate into existing AIDC power architectures through fast‑response Power Conversion Systems (PCS) and is also compatible with next‑generation high‑voltage DC systems using high‑efficiency DC/DC converters, achieving response times under 10 milliseconds.

With this launch, HiTHIUM states it has established a multi‑layer, full‑scenario smart energy security system that spans source, grid, and load. The system aims not only to ease current tensions between computing growth and power availability, but also to lay a future‑ready foundation of green, agile, stable, and economical support for the AI industry.
