Which energy storage technologies are included in the cost and performance assessment?
The Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.
How much does energy storage cost?
Chiang, professor of energy studies Jessika Trancik, and others have determined that energy storage would have to cost roughly US $20 per kilowatt-hour (kWh) for the grid to be 100 percent powered by a wind-solar mix. Their analysis is published in Joule. That’s an intimidating stretch for lithium-ion batteries, which dipped to $175/kWh in .
How long does an energy storage system last?
The Cost and Performance Assessment analyzed energy storage systems from 2 to 10 hours. The Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations.
Are battery storage costs based on long-term planning models?
Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.
What is the levelized cost of Storage (LCOS) metric?
The levelized cost of storage (LCOS) ($/kWh) metric compares the true cost of owning and operating various storage assets. LCOS is the average price a unit of energy output would need to be sold at to cover all project costs (e.g., taxes, financing, operations and maintenance, and the cost to charge the storage system).
Do projected cost reductions for battery storage vary over time?
The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time. Figure ES-1 shows the suite of projected cost reductions (on a normalized basis) collected from the literature (shown in gray) as well as the low, mid, and high cost projections developed in this work (shown in black).
