Its not bunk. People are comparing two widely different things and not understanding the difference. The price of $150 is capacity of a battery. If i want a battery that can store 4 kwh i pay $600. The other number referencing $55/MWh is referencing levelized cost of storage.
I have a a MWh but instead of using it right now i store it for 4 hours.
Now this MWh costs its initial price + $55. Apply this example to a KWh where i would pay $0.1 for it if i used it right now
if i want to store it for 4 hours and use it later i have to add $55/1000
to the price or about $0.055.
So a directly used KWh would cost me $0.1. One stored for 4 hours would cost me
$0.15. Hope that makes sense and explains these different numbers. |
