According to EnergyTrend, BYD and Hithium have rolled out brand new energy storage products over the past two days.
On September 15, BYD Energy Storage unveiled its GW class Grid Forming Energy Storage Solution 2.0. On September 16, Hithium launched its new generation integrated sodium ion energy storage solution, focusing on the industrialization of sodium ion batteries with clear timelines for mass production.
BYD Energy Storage: Launches Standardized GW Scale Power Station Solution
The 2026 Shenzhen International Digital Energy Exhibition runs from September 15 to 17. At the show, BYD Energy Storage premiered the new GW class Grid Forming Energy Storage Solution 2.0.
Centered on the standardized GC Block power station unit, each Block reaches 62 MWh, integrating two core pieces of equipment: the MC Cube XT energy storage system and GC Flux PCS 2.0.
Specifically, the MC Cube XT energy storage system is equipped with 1980 Ah energy storage specific Blade Batteries, suited for long duration energy storage scenarios of 2 hours and above. The new GC Flux PCS 2.0 adopts a 20 foot container design with a single unit power output of 10 MW and a peak conversion efficiency of 99.50 %. It delivers 3 times overload capability for 10 seconds, greatly enhancing extreme operation and fault tolerance performance.
Furthermore, the full solution enables minute level black start capability for GW scale energy storage power stations, supporting stable 7×24 hour uninterrupted power supply.
Hithium: Mass Production Delivery Planned for 2027
On September 16, Hithium released its new generation integrated sodium ion solution dedicated to energy storage. Its flagship offering is the ∞Power N4.0 MWh sodium ion energy storage system powered by ∞Cell N785 Ah large capacity sodium ion batteries. Full chain mass production delivery is scheduled for 2027.
At the cell level, the ∞Cell N785 Ah battery features jointly developed NFPP cathode material and in house developed hard carbon anode, paired with an electrolyte formula using “micro bonding + targeted repair” technology. Manufacturing leverages ultra thick coated electrodes, long life structural components and wide format large stacking processes. The cell achieves a cycle life of 20 000 cycles for 2 to 8 hour utility scale energy storage use cases, and is compatible with existing kilo ampere hour lithium ion production and integration platforms.
On the system side, ∞Power N4.0 MWh comes with sodium ion optimized BMS featuring SOC estimation accuracy ≤ 2.5 %. It supports 800 V 1500 V power conversion systems, with PCS rated power utilization improved by over 20 % versus the prior generation sodium ion system.
The system adopts air liquid hybrid cooling plus AI driven intelligent thermal management, with built in weather monitoring and early warning functions. Site footprint is reduced by 30 %, all weather comprehensive energy efficiency exceeds 88 %, operational auxiliary losses drop by 30 %, and standby auxiliary losses decrease by 50 %. Engineered for a 30 year service life, it matches the design lifespan of power infrastructure.
Hithium also notes that sodium ion development must balance resource accessibility and affordable costs. The target is to bring sodium ion costs on par with lithium ion batteries when lithium carbonate is priced at 150 000 CNF per tonne.
The company has also kicked off the “∞Edge Pioneer Initiative”. Over the next three years, it will conduct battery tests under diverse extreme environments, continuously release technical packages for harsh condition applications, and push energy storage LCOS toward the target of 0.1 CNF per kWh. Beyond large scale utility storage, future product applications will extend to commercial industrial and residential energy storage segments.
