This may be only the second residential scale flow battery launched, but I've definitely seen and met a number of companies with units in development. In fact I'm sure Schmidd have one. Anyway. It will be very interesting to see how this European manufacturer does. Of course even in Germany, space if more of a premium than Australia, and in a basement or garage size matters, as well of course does safety. Let's see if at last we can see a flow battery success story!
