World : The best battery for grid level energy storage

A new paper published by researchers at China’s Tianjin University examines the state of the art in grid level energy storage, outlining the pros and cons of various battery technologies being deployed on grids around the world, and remaining challenges that could be overcome if research is pushed in the right direction.

The continued growth of renewables in the global energy mix is inextricably linked to grid level energy storage, which can smooth out the inherent intermittency of solar and wind generation, ensure that generated power is in the right place to meet demand and provide a range of other services to the grid.

While lithium-ion is the best-known storage technology today, a range of different battery technologies offers the potential to provide valuable services to electricity grids around the world, each with its own advantages and disadvantages.

In a new paper, researchers at Tianjin University in China examine these battery technologies, providing a broad perspective on the state of battery technology for grid applications today, and offering a roadmap to guide future studies in this areas. Their findings are published in the paper Battery Technologies for Grid-Level Large-Sale Electrical Energy Storage, published in Transactions of Tianjin University.
