HiTHIUM Unveils 8-Hour LDES and New Technologies at SNEC 2026

On June 3, 2026, HiTHIUM— a prominent global provider of energy storage solutions— showcased their first long-duration energy storage (LDES) system designed for eight hours at the SNEC 2026 exhibition. This innovative solution, known as the ∞Power system, has a capacity of 6.9 MWh, marking a significant evolution in energy storage technology.

The need for efficient and robust energy storage solutions has never been greater, especially as renewable energy deployment expands worldwide. Traditionally, energy storage lasted between two to three hours. However, this landscape is rapidly changing with increasing calls for storage durations of four to eight hours. LDES is now crucial for integrating renewables into the grid, ensuring flexibility, reliability, and the stable operation of electrical systems.

In response to the pressing demand for cost-effective and large-scale solutions within the LDES era, HiTHIUM has developed a comprehensive technological framework. This framework encompasses dedicated battery cells and integrated battery energy storage systems (BESS), anchored by HiTHIUM’s strengths in cost leadership, service quality, and reliability.

The new 8-hour LDES system is redefining industry standards by delivering significant value. During the exhibition, HiTHIUM's Product Director, Kay Ye, delivered a keynote address titled, "Long-Duration Energy: Green Sustained Solutions for Ultra-Long Storage Systems and New Product Launches." She highlighted that with the rising penetration of renewable energies, increasing frequency of extreme weather events, and pressing demand for energy reliability, LDES is solidifying its role as an essential infrastructure for electrical system security.

The 6.9 MWh LDES ∞Power system is a remarkable innovation, powered by the world's first dedicated LDES battery cell with a 1300 Ah capacity. This system is designed at the cell level to ensure over 6.9 MWh of capacity and a stable eight-hour discharge within a standard 20-foot container. It boasts a lifespan of up to 25 years, supporting both parallel and tandem installations, thereby reducing land use and project construction costs.

Moreover, the system adopts eco-friendly innovations, such as low GWP refrigerants, leak prevention designs, and recyclable structural components. For enhanced safety, HiTHIUM has devised a multi-layered protection architecture, integrating intrinsic cell safety, active and passive container-level safety measures, and intelligent battery management systems (BMS).

Alongside the LDES system, HiTHIUM also introduced the high-capacity energy storage battery, the ∞Cell 650Ah, and the ∞Power solution with a capacity exceeding 10 MWh. Buoyed by formidable R&D capacities in battery cells and energy storage solutions, HiTHIUM continues to enrich its product portfolio, centering on customer value.

The newly launched products enhance HiTHIUM’s high-capacity battery and system offerings while boosting overall project profitability through increased energy density and improved system integration efficiency. This broad array of options caters to diverse scenarios, thereby elevating HiTHIUM's global competitiveness.

In a significant move to expand its footprint in Southeast Asia, HiTHIUM announced a three-year strategic cooperation agreement valued at 1 GWh with DSS Solar for the residential, commercial, and industrial energy storage markets in Vietnam. This collaboration merges HiTHIUM’s expertise in product solutions, advanced manufacturing, and supply chain capabilities with DSS Solar’s local channel networks and project development services. This partnership aims to promote large-scale implementation across Vietnam and bolster regional energy transition and green development.

Looking ahead, HiTHIUM, with a focus on lithium and sodium-ion battery technologies, plans to further develop a comprehensive range of products catering to application needs from one to eight hours. The company remains committed to driving innovation and global expansion as it accelerates large-scale implementation and supports global green energy transitions.
