As Long-duration Energy Storage（LDES） becomes central to overcoming renewable intermittency and enabling all-weather green power, the third HiTHIUM Eco-Day was concluded under the theme of “The Awakening of Energy – The New World”. The event brought together global LDES experts, AIDC（AI Data Center）industry leaders and partners from across the energy ecosystem, also marking the global launch of three major innovations: the ∞Power8 6.9MW/55.2MWh 8-hour-native solution, the ∞Cell 1300Ah, dedicated 8h LDES Cell, and the ∞Power Solutions for AI Data Center, a full-duration collaborative lithium–sodium energy storage solution.
During his opening remarks, HiTHIUM Co-founder and CEO Jason Wang noted the core path to shift green power from “weather-dependent” to “stable and easy to use” is energy storage, especially LDES. To advance this vision, the company officially launched its “All-Weather Green Power · 135 Lighthouse Plan.” Centred on LDES and guided by the mission of co-creating a new world of always-available green energy, the five-year initiative focuses on three action pillars—green intelligent computing, comprehensive storage deployment, and green power hubs—aiming to extend the “lighthouse light” of LDES across all industries.
Industry experts from around the world joined the discussion, with Wood Mackenzie Senior Analyst Alex Cipolla sharing insights on global LDES trends, applications and technology pathways and Zhihua Liu, Solutions Director for the South China region of Eaton Power Shanghai, also sharing the company’s innovations in high-voltage DC and intelligent power distribution.
As the highlight of the Eco-Day, HiTHIUM unveiled three groundbreaking technologies:
∞Power8 6.9MW/55.2MWh, the world’s first 8-hour-native LDES solution, engineered for all-weather renewable smoothing, multi-hour shifting and stable green power delivery.
∞Cell 1300Ah Dedicated 8-Hour Cell, a next-generation high-capacity cell enabling 8-hour cycling, 20+ years of service life, superior safety and significantly lower LCOE.
∞Power Solutions for AI Data Centre, the industry’s first lithium–sodium full-duration solution, combining long-duration lithium storage with high-rate sodium-ion for millisecond-level response, built to meet AIDC’s dual needs for long-term stability and instantaneous power support.
At an AIDC roundtable hosted by HiTHIUM Board Member and VP Dr. Nazar Yi, experts from telecom operators, data centre companies and industry associations engaged in discussions as to whether LDES represents the “missing piece” in enabling zero-carbon AIDCs. It was noted that AIDCs face increasing tension between soaring computing demand and constrained energy supply and that lithium-based LDES presents a key pathway to improving stability, lowering costs and enabling scalable development.
The event subsequently featured the joint release of the 2025 ‘China AIDC Energy Storage Bluebook’ produced by HiTHIUM and leading industry organizations. The report outlines AIDC energy consumption trends, evolving BBU requirements and the growing importance of LDES to AIDC energy constraints, providing detailed analysis from industry demand to deployment strategies.
In his closing remarks, HiTHIUM Founder and President Jeff Wu highlighted that energy storage must match wind and solar, not only in terms of lifespan but also cost. To achieve this, HiTHIUM will focus on four priorities: developing ultra-large, high-safety, long-life cells; building safer, more integrated, and more efficient systems; advancing intelligent manufacturing; and delivering fully integrated energy storage solutions.
