HiTHIUM, a global provider of integrated energy storage solutions, has made its international debut of an 8-hour long-duration energy storage (LDES) system at the World Future Energy Summit (WFES) 2026 in Abu Dhabi, positioning the technology as a key enabler of all-day renewable power supply.
Showcased from January 13 to 15 at the Abu Dhabi National Exhibition Centre, the company’s flagship offering — the ∞Power 6.9MWh battery energy storage system (BESS) and its core component, the ∞Cell 1300Ah LDES cell — is designed to support continuous green electricity generation, particularly in regions with extreme climate conditions such as the Middle East.
With renewable energy capacity expanding rapidly across the region, power grids are facing growing pressure to balance daytime solar output with nighttime demand while maintaining reliability under high temperatures. HiTHIUM said its new system has been engineered at the cell, system architecture and safety levels to meet these challenges.
The ∞Power 6.9MWh system features a purpose-built architecture for long-duration applications, cutting material usage and improving assembly efficiency. According to the company, intelligent controls and active balancing technology reduce auxiliary power consumption by more than 30 percent, improve temperature regulation accuracy by 20 percent, and increase balancing efficiency by nearly 20 times compared to conventional systems.
Safety enhancements include high-strength steel reinforcement, a dual pressure-relief venting design and next-generation thermal insulation materials, allowing stable operation at temperatures of up to 800°C and pressures of 300 kPa.
At the core of the solution, the ∞Cell 1300Ah cell delivers more than four times the capacity of mainstream battery cells, reducing system component count by over 30 percent and lowering upfront investment costs. The company said its multi-level safety architecture prevents thermal runaway propagation, while ultra-thick electrode technology improves durability, cost efficiency and overall lifespan.
During the summit, HiTHIUM also signed an agreement with Infinity Power to supply a 120 MWh energy storage system for the Nefer Benban renewable energy project in Aswan, Egypt. The project marks a major expansion of HiTHIUM’s footprint in the Middle East and North Africa (MENA) region and is expected to support grid stability and large-scale renewable integration.
Company officials said HiTHIUM plans to accelerate the global deployment of long-duration energy storage systems as utilities and governments push for higher renewable penetration and round-the-clock clean power availability.
