HiTHIUM announced the launch of what it claims is the world’s first collaborative lithium–sodium full-duration energy storage solution designed specifically for AI data centers (AIDC), marking a major step toward building low-carbon, resilient power infrastructure for the rapidly expanding AI sector.
Unveiled at the company’s third Eco-Day, the new portfolio—branded as ∞Power Solutions for AI Data Center—combines long-duration lithium battery energy storage systems (BESS) with high-rate sodium-ion BESS to deliver end-to-end power support across multiple time scales. The portfolio includes ∞Power 6.25MWh (4-hour), ∞Power 6.9MWh (8-hour), ∞Power N2.28MWh (1-hour), and ∞Power 6.25MWh (2-hour) solutions.
HiTHIUM said the integrated approach establishes a coordinated “source–grid–load” energy framework, addressing AIDC requirements for sustainability, agility, grid stability, and cost efficiency, while enabling scalable, low-carbon AI infrastructure.
The company highlighted that surging AI workloads are driving sharp increases in electricity demand, while power infrastructure expansion typically takes five to ten years. AI data centers also generate extreme load fluctuations—sometimes up to 70 per cent within milliseconds—posing significant risks to grid stability and operational reliability if managed with conventional power systems.
Speaking at the event, HiTHIUM Board Member and Vice President Dr. Nazar Yi said overcoming these constraints requires a new energy architecture that supports rapid deployment and green, low-carbon development. He noted that HiTHIUM’s full-duration AIDC solution leverages long-duration energy storage at the energy source and a lithium–sodium collaborative system at the load side.
At the source level, the solution pairs long-duration storage with renewable generation such as solar and wind, reducing the power infrastructure construction cycle to one to two years. When renewable energy accounts for more than 80 per cent of an AIDC’s demand, HiTHIUM said 8-hour LDES can significantly lower the levelised cost of electricity, hedge against power price volatility, and support grid services including frequency regulation, black-start capability, and zero-carbon backup.
At the grid and load level, the system introduces a bi-directional stabiliser built on the collaboration between high-rate sodium-ion and long-duration lithium-ion storage. The sodium-ion system delivers ultra-fast discharge to smooth load fluctuations within milliseconds, creating what the company describes as a dynamic “electromagnetic shield” for both the grid and the data centre.
HiTHIUM said its self-developed sodium-ion cells offer more than 25 years of service life, improve overall system efficiency by over three per cent, and balance instantaneous power response with long-term durability. The lithium-based long-duration backup system, meanwhile, offers a cleaner alternative to diesel generators, with lifecycle costs more than 20 per cent lower for a four-hour backup duration, enabling silent, zero-carbon backup power for AI campuses.
The solution can be integrated into existing AIDC power architectures through fast-response power conversion systems, and is also compatible with next-generation high-voltage DC systems via high-efficiency DC/DC converters, achieving response times of under 10 milliseconds.
With the launch of the full-duration lithium–sodium portfolio, HiTHIUM said it has established a multi-layered, full-scenario smart energy security system covering the energy source, grid, and load. The company added that it will continue to drive deeper integration between AI and energy, applying AI across research and development, manufacturing, and operations to better align computing growth with sustainable power supply.
