Energy storage cabinet soundness hinges on UHPC wall construction

NHOA.TCC integrated the EnergyArk cabinet (below, center) with Molicel, Taiwan Cement Group’s high-end lithium battery company, and a Molicel-powered McMurtry Spéirling race car for the Consumer Electronics Show booth.

A subsidiary of Taiwan Cement Corp., Taipei, stressed inherent fire and heat resistance, along with structural integrity, in the ultra-high performance concrete centerpiece of its Consumer Electronics Show 2024 booth. The early-2024 Las Vegas Convention Center gathering afforded NHOA.TCC a global venue for the EnergyArk battery storage cabinet launch. Available in three sizes for electric vehicle charging or commercial level power, the cabinet has panels of UHPC whose compressive strength exceeds 15,000 psi and robust nature provides two hours of protection to heat hovering 1,050°C (1,920°F).

NHOA.TCC developed EnergyArk for indoor or outdoor installations and as an alternative to conventional metal containers. Beyond UHPC construction, the cabinet is equipped with a self-developed energy management system; in the event of overheating, a fire extinguishing system automatically submerges the battery assembly in water while maintaining cabinet integrity. International market readiness is indicated by EnergyArk performance in testing or evaluation per UL 9540, Energy Storage System Requirements; NFPA 855 Standard for the Installation of Stationary Energy Storage Systems; and, (International Electrotechnical Commission) IEC 62933-5-2, Safety requirements for grid-integrated electrical energy storage systems.

EnergyArk Engineers turned to UHPC keen on eliminating risks related to various energy storage batteries and building a structure imperious to disaster. “When it comes to the energy structure of the future, storage cabinets are set to become an indispensable piece of social infrastructure,” NHOA.TCC notes. “The EnergyArk is capable of overcoming the intermittent nature of renewable energy, solar or wind.”
