In this work we describe the development of cost and performance projections for utility-scale lithium-ion battery systems, with a focus on 4-hour duration systems. The projections are developed from an analysis of recent publications that include utility-scale storage .

Iron-air batteries use a process called “reversible rusting” to store electricity, converting iron into rust and rust back into iron in a cycle that can store an electrical current.

Lithium-ion (LiFePO4) rack batteries outperform lead-acid counterparts in energy density (150-200 Wh/kg vs. 30-50 Wh/kg), cycle life (3,000-5,000 cycles vs.
