Storage Methods
Background
For isolated, non-grid connected communities storage is critically important for system balance and to ensure a continual supply of power during times of low generation. Depending on the installed capacity of the system and the type of technology employed, different storage types and sizes could be more suitable than others. We investigated over 25 different storage mechanisms initially, ranging from mechanical, thermal and electromagnetic storage to batteries both chemical and flow.
After assessing each mechanisms viability for energy storage and network management, this number was narrowed down to twelve which were further assessed using a weighted matrix comprising of 15 different parameters. Each storage type was then scored on each of these factors and the best devices were selected to be put forward as recommendations.
Below are a selection of some of the highest-scoring storage mechanisms:
