Can Energy Storage Make Wind and Solar Energy as Reliable as Coal?
Wind and solar power generated 3.5% and about 0.1%, respectively, of US electricity last year. These figures represent large increases from much smaller levels in the last decade as the cost of these technologies declined significantly, particularly for solar photovoltaic (PV) modules. However, other barriers to wider deployment remain, including their intermittent output. Energy storage is often portrayed as the killer app for overcoming the intermittency of renewables, and a number of interesting developments have occurred...
