Few nations can take more credit for the rise of renewables than Germany, and where renewables grow, storage is usually sure to follow.
But Germany's situation differs from the U.S. and U.K. in that it maintains significant coal usage instead of shutting it down. And its highly interconnected grid has many outlets for surplus renewable production, reducing the need to store power locally.
Those factors, plus certain market rules, have made it harder to launch a grid-scale storage industry than it might appear, given Germany's solar and wind adoption.
In fact, the only place where storage business is booming is in residential — the market that remains most marginal in other countries.
In this week's Storage Plus, we'll unpack the prevailing trends on the German grid, the challenges facing utility- and commercial-scale development, and what makes home batteries so hot.
