Why are NMC batteries a good choice?

Alternatively, increasing the share of manganese favours higher specific power. Therefore, NMC batteries exhibit balanced overall performance in specific power, safety, thermal stability, lifespan, and cost, while they excel in terms of specific energy (in the range of 140-200Wh/kg).

How much does a battery cost in 2026 vs 2031?

Figure 16 above illustrates this, with a relatively minor expenditure on batteries in years 2026 and 2031 vs the single major expenditure in 2031 (see Figure 14). The resulting LCOE is about 11% lower, at 0.34 USD/kWh vs the 0.38 USD/kWh with a battery replacement in year 10.

How much does a battery cost drop compared to a project start?

The most significant drop of 90% is for case A-1 with a project start in 2035, or 55% with a project start in 2021. This is partially due to the grant funding that is applied to this case, as lower cost batteries convert the grant from a reduction of investment to making cash available (i.e. the grant is larger than the investment).
