What is the absorption capacity of mobile energy storage in China?

In terms of mobile energy storage, Northeast China has a unit capacity absorption ranging from 30 kWh to 90 kWh, compared to 15 kWh to 56 kWh in North China. (2) As the share of renewable energy in the system increases, the absorption capacity of fixed energy storage initially rises and then declines, with 50% and 55% as the inflection points.

Should solar power stations be used for mobile energy storage?

Additionally, setting the solar power station as a supply point for batteries, and utilizing a combined wind and solar energy supply could further enhance the complementary use of these resources, benefiting mobile energy storage.

Is mobile energy storage a viable alternative to fixed energy storage?

Mobile energy storage can improve system flexibility, stability, and regional connectivity, and has the potential to serve as a supplement or even substitute for fixed energy storage in the future. However, there are few studies that comprehensively evaluate the operational performance and economy of fixed and mobile energy storage systems.

What is the total system cost of mobile energy storage?

The total system cost of mobile energy storage is the same as that of fixed energy storage, including investment cost, operating cost, and recovery cost. Unlike mobile energy storage, which incurs transportation costs during energy transportation, fixed energy storage incurs line transportation costs during energy transportation.
