From your ref -
"The levelized cost of storage (LCOS) is analogous to LCOE, but applied to energy storage technologies such as batteries.[10] Regardless of technology, however, storage is but a secondary source of electricity dependent on a primary source of generation. Thus, a true cost accounting demands that the costs of both primary and secondary sources be included when the cost of storage is compared to the cost of generating electricity in real time to meet demand.[citation needed]
A cost factor unique to storage are losses that occur due to inherent inefficiencies of storing electricity, as well as increased CO2 emissions if any component of the primary source is less than 100% carbon-free.[11] In the U.S., a comprehensive 2015 study found that net system CO2 emissions resulting from storage operation are
nontrivial when compared to the emissions from electricity generation [in real time to meet demand], ranging from 104 to 407 kg/MWh of delivered energy depending on location, storage operation mode, and assumptions regarding carbon intensity.[11] "
You do understand NON-TRIVIAL?
