HiTHIUM’s Groundbreaking Open-Door Fire Test

In a significant advancement for energy storage safety, HiTHIUM has successfully completed the world’s first large-scale open-door fire test of its advanced 6.25MWh long-duration energy storage (LDES) system, utilizing kiloampere-hour (kAh) battery cells. The test, conducted under strict supervision by representatives from UL Solutions and various U.S. regulatory authorities, adhered to the latest standards established by UL 9540A and NFPA 855. This achievement not only highlights HiTHIUM’s commitment to safety in energy storage technology but also sets a new standard for large-scale energy systems worldwide.

Test Methodology and Parameters

This ambitious testing initiative sought to evaluate the performance and safety of the ∞Power 6.25MWh energy storage system under extreme conditions. Unlike typical tests, the container doors remained fully open throughout, simulating a scenario where enhanced oxygen supply could influence combustion. The setup involved multiple containers positioned closely together, with only a 15 cm gap between them, while the system was charged to 100% capacity and fire suppression systems were purposely disabled to focus on intrinsic safety mechanisms.

Safety Performance Highlights

Controlled Energy Release

The results of the test were promising; the high-energy-density system maintained stable and controllable performance even in adverse conditions. HiTHIUM employed a three-dimensional airflow channel designed for effective gas venting during thermal runaway scenarios, combined with a dual pressure relief valve system. This design successfully mitigated the possibility of explosive incidents, with no explosions or debris ejection recorded during the test.

Fire Containment Measures

In terms of fire control, HiTHIUM’s multi-layered safety approach proved effective. Fire-resistant module covers and robust steel enclosures confined any fire to a single battery system, preventing thermal propagation across the adjacent containers. Remarkably, the temperatures recorded in surrounding cells remained safely below critical thresholds, showcasing the effectiveness of the safety designs.

Structural Integrity Under Stress

The structural resilience of the ∞Power 6.25MWh system was equally impressive. Reinforced with high-strength steel frameworks and dual-layer partitions, the system exhibited no significant deformation or failure even after prolonged exposure to high thermal stresses. The container housing the energy storage system remained intact throughout the entire test duration.

A New Standard for Energy Storage Safety

This pioneering test represents a milestone in global energy storage safety validation efforts. By demonstrating the safety performance and reliability of its LDES systems, HiTHIUM is paving the way for broader industry adoption of high-capacity energy storage solutions. As energy demands continue to surge and the push for sustainable energy escalates, advancements like these become essential in fostering public and industry confidence.

Looking ahead, HiTHIUM remains focused on pushing the boundaries of safety in energy storage technologies. The company is dedicated to setting higher benchmarks for safety and reliability through rigorous design standards and comprehensive testing methodologies. They are poised to collaborate with industry leaders to develop enhanced global standards that support the lethal deployment of LDES systems and fortify the transition to a sustainable energy future.

Through strategic innovations, HiTHIUM aims not merely to advance its technology but to enhance the overall safety framework for energy storage worldwide. With such achievements, HiTHIUM is well on its way to contributing significantly to a more resilient energy infrastructure and supporting the global endeavor for a cleaner tomorrow.
