Misconceptions About Battery Storage
By Paul Homewood There is a very common misconception that battery storage can solve the the problems of intermittency arising from renewable energy sources. For instance, there was a this little exchange on the Telegraph article today about wind farms along the HS2 route to power the train: https://www.telegraph.co.uk/politics/2019/01/26/wind-farms-could-built-along-route-hs2-confidential-government/ What the public at large, represented by Mr. Truth, don't seem to understand is just how limited the amount of energy that can be stored really is.

And for this tiny amount of storage, the Australians paid an estimated A$150M, about E80m.
