Prospects for large-scale energy storage
Posted: Fri 01 Mar 2013, 08:17:14
I'd like to start thread on this topic because there isn't one. There is one on compressed air storage but this thread is for other storage technologies too, in particular, the development and recent advances in energy storage. I'll start with an assessment by IEA in 2009, and a second by EU Parliament in 2008.

Prospects for large-scale energy storage in decarbonised power grids
The extent to which a power system can accommodate variations in supply is governed to a large extent by its flexibility – a measure of how fast and how much the system can quickly increase or decrease supply or demand, to maintain balance at all times. A range of measures exist to increase the flexibility of power systems, and thus the extent to which they can accommodate variable renewables. This paper looks at one of these measures – storage.
As mentioned above, as each storage system has different specifications, the optimal arrangement of these systems depends on circumstances in individual countries. In Annex 1, the current technical potential of NaS cells, pumped hydro, redox flow cells, Compressed Air Energy Storage (CAES), electric double-layer capacitors, Li-ion batteries, Superconducting Magnetic Energy Storage (SMES) and flywheel systems is reviewed. Reducing costs of such storage technologies may be a key to expanding the use of energy storage technologies to keep pace with the growth of variable renewables.

This report provides an overview of the current status and outlook for energy storage technologies.
Section 1 introduces energy storage and sets out the scope of this study. It also discusses some of the potential applications of the different technologies and reviews briefly some of the economic and environmental issues arising from their deployment. Section 2 sets out an inventory of energy storage technologies, showing how these technologies fall into a number of different technical types. This section also provides a summary of the characteristics of the technologies and their advantages and drawbacks. Section 3 provides a brief summary of the main international research programmes and activities that are in place to support the development of these technologies. Section 4 reviews the most promising technologies for the main potential applications Section 5 considers the policy challenges relevant to the deployment of energy storage technologies, to help in the development of appropriate recommendations. Section 6 sets out a number of appropriate recommendations.
