Energy storage consultant Anthony Price ponders the demise of Regenesys, and wonders if flow batteries can feature again in power utility plans.
Pumped storage in a box is a good description of a flow battery. Pumped storage pushes water uphill to increase its potential energy so that it can be released at a later time to turn turbines and generate electricity. If you need more power, the ratings of the turbines can be increased; and more energy storage can be obtained by increasing the size of the reservoir. With a flow battery more power is available by increasing the . . .
