Flow battery developers must balance meeting current market needs while trying to develop longer duration systems because most of their income will come from the shorter discharge durations. Currently, adding additional energy capacity just adds to the cost of the system.
Valuation of Long-Duration Storage: Flow batteries are ideally suited for longer duration (8+ hours) applications; however, existing wholesale electricity market rules assign minimal incremental value to longer durations.
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.

Flow batteries: Design and operation A flow battery contains two substances that undergo electrochemical reactions in which electrons are transferred from one to the other. When the battery is being charged, the transfer of electrons forces the two substances into a state that’s “less energetically favorable” as it stores extra energy.
Batteries are manufactured in various sizes and can store anywhere from <100 W to several MWs of energy. Their efficiency in energy storage and release, known as round-trip ES efficiency, is between 60 and 80 %, and this depends on the operational cycle and the type of electrochemistry used.
High-tech membranes, pumps and seals, variable frequency drives, and advanced software and control systems have brought greater eficiencies at lower expense, making flow batteries a feasible alternative to lithium-ion storage systems. Each flow battery includes four fuel stacks in which the energy generation from the ion exchange takes place.

Lithium-ion batteries can generally only hold up to four hours of energy, and many projects have been built with less than that (the average duration of energy that can be provided by battery storage projects in the United States is about 2.7 hours).
In the coming decades, renewable energy sources such as solar and wind will increasingly dominate the conventional power grid. Because those sources only generate electricity when it''s sunny or windy, ensuring a reliable grid — one that can deliver power 24/7 — requires some means of storing electricity when supplies are abundant and delivering it later …
