HiTHIUM Unveils 8-Hour Long-Duration Energy Storage Solution at WFES 2026

From January 13 to 15, the World Future Energy Summit (WFES) took place at the Abu Dhabi National Exhibition Centre. HiTHIUM, a globally leading provider of integrated energy storage solutions and services for full-scenario applications, presented a wide range of energy storage products, highlighting its system-level expertise across varied use cases. A key focus was the debut of its 8-hour long-duration energy storage (LDES) solution, featuring the ∞Power 6.9MWh 8h LDES system—engineered for round-the-clock green power—and its core component, the ∞Cell 1300Ah 8h dedicated LDES cell. This exhibition marked the first international showcase of HiTHIUM’s 8-hour LDES technology.

With renewable energy capacity growing rapidly across the Middle East, power systems increasingly require long-duration flexibility, day-night balancing, and reliable operation under high temperatures. To meet these demands, HiTHIUM has developed a system-level LDES solution that covers cell design, system architecture, and safety protocols, offering robust support for building resilient, all-weather green energy infrastructure in the region.

The ∞Power 6.9MWh BESS utilizes a new architecture tailored for 8-hour LDES applications, achieving advances in cost-effectiveness, operational performance, and safety. By minimizing redundant structural parts, the system cuts material costs and raises assembly efficiency. Its intelligent control systems and end-to-end active balancing strategy reduce auxiliary power consumption by over 30%, increase temperature control accuracy by 20%, and improve balancing capability by around 20 times compared to traditional alternatives. Additionally, the system incorporates high-strength steel band reinforcement, a dual pressure-relief venting design, and next-gen thermal insulation materials, allowing stable performance under extreme conditions of up to 800°C and 300 kPa pressure.

At the heart of the native 8-hour long-duration storage solution is the ∞Cell 1300Ah dedicated LDES cell, which achieves breakthroughs in capacity, safety, and cycle life. With a single-cell capacity of 1300Ah—more than four times that of mainstream cells—it reduces system components by over 30%, effectively lowering upfront investment. A multi-layer safety protection system prevents thermal runaway propagation, while HiTHIUM’s proprietary ultra-thick electrode technology overcomes challenges such as electrode cracking and electrolyte infiltration, enhancing both performance and cost efficiency.

During the event, HiTHIUM Energy Storage held a signing ceremony with Infinity Power to deliver a 120 MWh energy storage system for the Nefer Benban project in Aswan, Egypt. This agreement further expands HiTHIUM’s footprint in large-scale energy storage across the MENA region, strengthening local renewable integration and grid stability.

Moving forward, HiTHIUM will continue to advance technological innovation, deepen cooperation with global partners, and accelerate the widespread adoption of long-duration energy storage solutions throughout the Middle East and around the world.
