Unigrid has developed sodium-ion batteries capable of lasting 20-25 years with over 80% initial energy capacity retention. The company plans to introduce a zero-down leasing model, which would allow users to benefit financially while reducing upfront costs.
Unigrid's batteries can achieve up to 95% capacity retention after 5,000 charge-discharge cycles. Production is set to ramp from 100 MWh per year in Q4 2025 to 1 GWh in 2026. The company will test this model in California, offering a zero-export energy storage product that reduces demand and peak energy charges for businesses. This leasing model could revolutionize energy storage, similar to how home solar has transitioned to third-party ownership.
