HiTHIUM has announced the launch of what it claims is the world’s first collaborative lithium–sodium full-duration energy storage solution targeting artificial intelligence data centers (AI data centers). The new ∞Power Solutions for AI Data Center portfolio includes the ∞Power 6.25 MWh 4h, ∞Power 6.9 MWh 8h, ∞Power N2.28 MWh 1h, and ∞Power 6.25 MWh 2h systems. Each offering combines long-duration lithium battery energy storage system (BESS) technology with high-rate sodium-ion BESS, forming a coordinated “source-grid-load” energy framework.
According to HiTHIUM, one of the primary challenges for AI data centers is the rapid increase in energy demand, which outpaces conventional grid infrastructure development and creates unstable load fluctuations—up to 70 percent changes in tens of milliseconds. To address these issues, the company claims its solution combines long-duration energy storage at the source side with a collaborative lithium–sodium configuration at the load. This approach targets agility, scalability, and operational stability while enabling lower-carbon and resilient infrastructure.
The portfolio is designed for direct coupling with renewable sources such as solar and wind. HiTHIUM notes that this allows energy infrastructure buildout within one to two years, compared to conventional timelines of five to 10 years. The eight-hour long-duration system is intended to maximize renewable value for data centers sourcing over 80 percent of demand from renewables, reduce levelized cost of energy (LCOE), mitigate electricity price fluctuations, and provide support for grid frequency control, black-start, and zero-carbon backup.
The company’s solution uses a high-rate sodium-ion component for instant discharge and load smoothing within milliseconds, addressing sharp fluctuations in compute demand. HiTHIUM reports its self-developed sodium-ion cells deliver more than 25 years of service life and can improve system efficiency by over three percent. The lithium-based backup system, with a four-hour backup window, offers over 20 percent lower lifecycle costs than conventional diesel generators, providing zero-carbon, silent backup power to campus-scale data centers.
HiTHIUM’s full-duration energy storage systems integrate with current AI data center power architectures using fast-response power conversion systems, and support next-generation high-voltage direct current (DC) deployments through high-efficiency DC-to-DC (DC/DC) converters. The systems are capable of response times under 10 milliseconds.
HiTHIUM claims this multilayer solution creates a “smart energy security system” that spans the energy source, grid, and load, aiming to provide scalable and efficient energy support for future AI infrastructure requirements.
