Emphasis is placed on storage technologies that are connected to a larger energy system (e.g. electricity grid), while a smaller portion of the discussion focuses on off-grid storage applications. This focus is complemented by a discussion of the existing technology, policy, and economic barriers that hinder energy storage deployment.
DOI 10.3386/w22752. Issue Date October 2016. The increasing importance of intermittent renewable energy sources suggests a growing importance for energy storage as a way of smoothing the variable output. In this paper I investigate factors affecting the amount of energy storage needed, including the degree of intermittency and the correlations ...
