Solar and wind power are sustainable energy sources. But they produce power only when the sun shines or wind blows. Powering city-sized electric grids reliably from intermittent sources requires storing electrical energy on an enormous scale.

Conventional batteries are not well suited to the task. Less common devices known as flow batteries offer potential advantages for storing electrical energy at the city scale. But their broad application has been limited by their dependence on costly, . . .
