HiTHIUM on Thursday announced the global launch of three major long-duration energy storage (LDES) innovations at its third Eco-Day event, reinforcing the role of advanced energy storage in enabling stable, all-weather green power and supporting the rapidly growing energy demands of AI data centers.
Held on December 12 under the theme “The Awakening of Energy · The New World,” the event brought together global LDES experts, AI data center (AIDC) industry leaders, and partners from across the energy ecosystem. As renewable energy adoption accelerates worldwide, the company positioned LDES as a strategic enabler to overcome intermittency and deliver reliable clean power.
During the opening address, HiTHIUM Co-founder and CEO Jason Wang said the transition of green energy from being “weather-dependent” to “stable and easy to use” hinges on the deployment of long-duration energy storage. To advance this goal, HiTHIUM officially launched its five-year “All-Weather Green Power · 135 Lighthouse Plan,” focused on three pillars—green intelligent computing, comprehensive energy storage deployment, and green power hubs.
Industry experts at the event shared insights on global LDES trends and technology pathways. Alex Cipolla, Senior Analyst at Wood Mackenzie, discussed the evolving role of LDES across markets, while Eaton Power Shanghai’s Zhihua Liu highlighted innovations in high-voltage DC and intelligent power distribution systems.
The centrepiece of the Eco-Day was the unveiling of three breakthrough technologies. These include the ∞Power8 6.9MW/55.2MWh solution, billed as the world’s first 8-hour-native LDES system designed for renewable smoothing, multi-hour energy shifting, and stable green power delivery. HiTHIUM also introduced the ∞Cell 1300Ah, a dedicated 8-hour LDES cell offering deep cycling capability, a service life exceeding 20 years, enhanced safety, and a significantly lower levelised cost of energy (LCOE).
The third launch was the ∞Power Solutions for AI Data Centers, the industry’s first full-duration lithium–sodium hybrid energy storage solution. The system combines long-duration lithium storage with high-rate sodium-ion technology to deliver millisecond-level response, addressing AI data centers’ need for both long-term stability and instantaneous power support.
A dedicated AIDC roundtable, hosted by HiTHIUM Board Member and Vice President Dr. Nazar Yi, examined whether LDES is the missing link in achieving zero-carbon AI data centers. Participants noted that rising computing demand and constrained energy supply are creating mounting challenges, with lithium-based LDES emerging as a key pathway to ensure stability, cost efficiency, and scalable growth.
The event also marked the joint release of the 2025 China AIDC Energy Storage Bluebook by HiTHIUM and industry partners. The report analyses AIDC energy consumption trends, evolving backup battery requirements, and the growing importance of LDES in addressing energy constraints.
In closing remarks, Founder and President Jeff Wu said energy storage technologies must match wind and solar power not only in lifespan but also in cost. He outlined HiTHIUM’s priorities, including the development of ultra-large, high-safety, long-life cells, more integrated and efficient systems, intelligent manufacturing, and fully integrated energy storage solutions.
Eco-Day, HiTHIUM’s flagship annual event, comes as the company ranks among the top two globally in energy storage battery shipments. Looking ahead, the company said it will continue to expand its technology portfolio, strengthen global partnerships, and contribute to clean energy development while shaping the future of energy storage in the AI era.
