Graph of the Day: Untapped potential of energy storage

These graphs of the day come courtesy of our friends from Cleantechnica. It comes from an article about a new developer of energy storage devices, Eos Energy, that claims it can deliver stored energy for as cheap as $160/kWh, which would be something a game changer for the industry. Cleantechnica covers this in full, as well as news that it has signed a contract with Con Edison.

What struck us was the collection of graphs that told the story about the energy storage industry in the world, or rather the lack of it. Here’s the first graph, pointing out, as the headline suggests, that the world’s largest supply chain has no storage.

Here is a graph showing where that (limited) capacity exists – almost all of it in pumped hydro, virtually nothing in other forms.

And here is the graph for the potential market size. Like solar PV, it will go from nothing to very big, in a very short period of time. That’s why it’s the next big thing in energy markets.
