Sodium-ion battery energy storage cost per watt

Are sodium ion batteries the future of energy storage?

There is also rapidly growing demand for behind-the-meter (at home or work) energy storage systems. Sodium-ion batteries (NIBs) are attractive prospects for stationary storage applications where lifetime operational cost, not weight or volume, is the overriding factor.

Are sodium ion batteries a good investment?

Analysing 30 LDES technologies, the research found sodium-ion batteries to hold the most promise due to their fast improvement rate – around 57% in 2024. They offer more efficiency in round-trip energy use, greater operational flexibility and lose less energy during storage and supply.

What is a sodium ion battery?

Overall, we provide a broad and interdisciplinary perspective on modern batteries and future directions for this field, with a focus on sodium-ion batteries. Sodium-ion batteries are an appealing alternative to lithium-ion batteries because they use raw materials that are less expensive, more abundant and less toxic.

What is the energy density of sodium ion batteries in 2022?

In 2022, the energy density of sodium-ion batteries was right around where some lower-end lithium-ion batteries were a decade ago—when early commercial EVs like the Tesla Roadster had already hit the road. Projections from BNEF suggest that sodium-ion batteries could reach pack densities of nearly 150 watt-hours per kilogram by 2025.

How much power does a sodium battery produce?

The first factory has about a 40 GWH per year capacity. China has 16 out of 20 globally planned or built sodium battery factories according to Benchmark Minerals. CATL’s first-generation sodium battery generates 160-watt-hours per kilogram. This is 10% less energy than iron LFP batteries and 40% less than mass produced nickel batteries.

What is a Technology Strategy assessment on sodium batteries?

This technology strategy assessment on sodium batteries, released as part of the Long-Duration Storage Shot, contains the findings from the Storage Innovations (SI) 2030 strategic initiative.
