Should EV batteries be used as stationary storage?

Low participation rates of 12%–43% are needed to provide short-term grid storage demand globally. Participation rates fall below 10% if half of EV batteries at end-of-vehicle-life are used as stationary storage. Short-term grid storage demand could be met as early as 2030 across most regions.

What is a battery energy storage system?

Battery energy storage systems (BESSs) are flexible and scalable, and can respond instantaneously to unpredictable variations in demand and generation. They can provide a variety of services for bulk energy, ancillary, transmission, distribution, and customer energy management [1, 2].

Can flow batteries be used for large-scale electricity storage?

Associate Professor Fikile Brushett (left) and Kara Rodby PhD ’22 have demonstrated a modeling framework that can help speed the development of flow batteries for large-scale, long-duration electricity storage on the future grid.

Do different grid-scale applications affect energy efficiencies of different battery chemistries?

The combined results of our economic modelling and cell-level testing demonstrate that different grid-scale applications affect the energy efficiencies of different battery chemistries in different ways.

How can energy storage help a vertically integrated utility?

Energy storage can be used by a vertically integrated utility to reduce operational costs and avoid or defer investment in generation, transmission, and distribution. Energy storage can participate in wholesale energy, ancillary, and capacity markets to generate revenue for storage owners.

What types of energy storage systems can esettm evaluate?

ESETTM currently contains five modules to evaluate different types of ESSs, including BESSs, pumped-storage hydropower, hydrogen energy storage (HES) systems, storage-enabled microgrids, and virtual batteries from building mass and thermostatically controlled loads. Distributed generators and PV are also available in some applications.
