The world’s wind resources are huge. But as wind becomes a larger fraction of electricity generation, grid integration must be resolved, particularly to smooth fluctuations in wind power output. Adding energy storage or back-up has been proposed as a solution, but dedicated storage or back-up adds capital cost to wind power. This article proposes vehicle-to-grid power (V2G) as a storage resource for large-scale wind power.
