Evaluation of Electrical Energy Storage (EES) technologies for renewable energy: A case from the US Pacific Northwest

- A review of storage technologies.
- A review of methods and applications for evaluating storage technologies.
- A taxonomy for industry and research.

Increase in use of renewable energy such as solar and wind has created challenges in balancing load. Renewable energy intermittency can be addressed with different solutions and technologies. Using Electric Energy Storage (EES) has been an approach which has been studied extensively in the recent years. This paper reviews the storage technologies leveraging both technical papers on technologies as well as other reviews of such technologies done by other researchers. The contribution of this paper is in two areas. First the use of a case study demonstrates how different approaches can address different challenges. Second contribution is the review of evaluation factors and methods of such technologies resulting in a proposed framework.
