Storage — whether of grain or of knowledge through the printed word — has been a crucial element in human development. Of all the many technical advances that are transforming the energy business none is potentially more important than storage: it give us the ability to control the way, and crucially the timing, of energy consumption. Used on a major scale it could help to make heat and light available to those outside the commercial economy and could radically alter the energy mix.
Two excellent recent research reports summarise the current state of the art in the field and offer some predictions. The first is from Lazards and is the latest in a series assessing trends in the costs of different mechanisms. The second is from Moody’s and concentrates on the advances being made in reducing the cost of batteries.
In discussing storage it is important to demolish two myths. First, the technological advances are not about to transform the energy system to the point where a major proportion of consumers defect from existing distribution systems. Second, it does not require a dramatic breakthrough for making it on a significant scale to become economic. Read more
