Generation Integrated Energy Storage
The objective of this work is to build a deep understanding of a class of system which takes a different and potentially much lower cost approach. These Generation Integrated Energy Storage (GIES) systems, store energy in a convenient form before converting it to electricity on demand. The hypothesis is that the lowest cost and highest performance storage can be achieved by integrating generation and storage. This avoids the expense and inefficiency of transforming primary energy (e.g. wind, solar, nuclear) into electricity, then into an intermediate form, and later back to electricity. For example, the heat produced by a concentrating solar power plant can be stored at far lower cost and with lower losses than producing electricity directly and operating a standalone electricity store.
