What is the 2020 grid energy storage technologies cost and performance assessment?

Pacific Northwest National Laboratory’s 2020 Grid Energy Storage Technologies Cost and Performance Assessment provides a range of cost estimates for technologies in 2020 and 2030 as well as a framework to help break down different cost categories of energy storage systems.

Which energy storage technologies are included in the 2020 cost and performance assessment?

The 2020 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 in a cavern?

Therefore, efforts to reduce cost of storage via engineering design are expected to gain traction. As long-duration energy storage (diurnal and seasonal) becomes more relevant, it is important to quantify cost for incremental storage in the cavern. The incremental cost for CAES storage is estimated to be $0.12/kWh.

How much does the Goldendale energy storage project cost?

The Goldendale Energy Storage Project has a head of 2,400 feet and is expected to cost $1,800/kW for C&I. Higher head for the project also reduced tunnel excavation costs due to the fact the pump/turbine centerline depth below the lower reservoir bottom decreased with increasing head (Miller, 2020a).

How do you calculate a unit energy cost metric?

The unit energy or power annualized cost metric is derived by dividing the total annualized cost paid each year by either the rated energy to yield $/rated kilowatt-hour (kWh)-year or by rated power to yield $/rated kilowatt (kW)-year, where the kWh and kW are rated energy and power of the ESS, respectively.

What are ESS costs & LCOE?

In addition to ESS costs, annualized costs and a levelized cost of energy (LCOE) of each technology are also provided to better compare the complete cost of each ESS over the duration of their individual usable lives.
