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.

How can energy storage help the electric grid?

Three distinct yet interlinked dimensions can illustrate energy storage’s expanding role in the current and future electric grid—renewable energy integration, grid optimization, and electrification and decentralization support.

Are energy storage technologies viable for grid application?

Energy storage technologies can potentially address these concerns viably at different levels. This paper reviews different forms of storage technology available for grid application and classifies them on a series of merits relevant to a particular category.

What happens when the grid requires power?

When the grid requires power, the cars are released and move downhill to drive the electric motors for converting the potential energy back into electricity.

How does grid connected energy storage affect environmental performance?

Round-trip efficiency, annual degradation, and generator heat rate have a moderate to strong influence on the environmental performance of grid connected energy storage. 28 Energy storage will help with the adoption of intermittent energy, like solar and wind, by storing excess energy for times when these sources are unavailable. 29

How much does grid integration cost?

Grid integration including transformers, meters, safety disconnects, and nominal labor costs added at $19.89/kW, same as for 100 MW lithium-ion battery system. Table 35 shows input values for capital cost obtained from Hunter et al. (In Press) for a 100 MW, 120-hour HESS.
