Energy generation and storage strategy are clearly a hot topic given the global circumstances. Here in the UK we’ve gone some way to solving the renewable generation problem – but we’re a long way from solving the storage problem. In other words when the wind doesn’t blow we haven’t stored enough energy to fill the gap before the wind picks up – hence the share of hydrocarbons required goes up.

CNN explored an interesting project which is looking at how to create storage in a very basic form; effectively storing the gravitational potential of an object. That can be done either above ground, or below ground (mine shafts).

The next few years is going to see a transformation in generation and storage capability; something almost laughably simple was great to see within the mix of hyper-complex emerging technologies in this field.
