4 FAQs about Price Reduction for Ultra-Large Capacity Mobile Energy Storage Containers

Are energy storage systems reducing the cost of batteries?

The scale of the reduction suggests that in addition to the falling cost of batteries—BNEF's recent Lithium-ion Battery Price Survey found that battery pack prices fell 20% year-on-year to 2024, again the biggest drop recorded to date—energy storage system providers are working on cost reduction in other areas, Kikuma said.

Why are battery energy storage systems (Bess) costs falling?

A growing industry trend towards larger battery cell sizes and higher energy density containers is contributing significantly to falling battery energy storage system (BESS) costs.

How much does a turnkey energy storage system cost?

According to BloombergNEF's recently published Energy Storage System Cost Survey 2024, the prices of turnkey energy storage systems fell 40% year-on-year from 2023 to a global average of US$165/kWh. The research firm said this was the highest annual drop since its survey launched in 2017.

Are there limitations to pursuing bigger and more energy dense solutions?

Although we have seen cell sizes and DC block energy density continue to increase—Hithium for example has announced, although not yet mass produced, 1,000Ah+ cells and EVE Energy has begun mass production of 628Ah cells —there may be some limitations to pursuing bigger and more energy dense solutions on a similar trajectory going forward.
