Stanford scientists calculate the carbon footprint of grid-scale battery technologies
Date:3/8/2013

-acid technology is at the bottom, achieving a mere 700 cycles.

"The most effective way a storage technology can become less energy-intensive over time is to increase its cycle life," Benson said. "Most battery research today focuses on improving the storage or power capacity. These qualities are very important for electric vehicles and portable electronics, but not for storing energy on the grid. Based on our ESOI calculations, grid-scale battery research should focus on extending cycle life by a factor of 3 to 10."

In addition to energetic costs, Barnhart and Benson also calculated the material costs of building these grid-scale storage technologies.

"In general, we found that the material constraints aren't as limiting as the energetic constraints," Barnhart said. "It appears that there are plenty of materials in the Earth to build energy storage. There are exceptions, such as cobalt, which is used in some lithium-ion technologies, and vanadium, the key component of vanadium-redox flow batteries."

Pumped hydro storage faces another set of challenges. "Pumped hydro is energetically quite cheap, but the number of geologic locations conducive to pumped hydro is dwindling, and those that remain have environmental sensitivities," Barnhart said.

The study also assessed a promising technology called CAES, or compressed air energy storage. CAES works by pumping air at very high pressure into a massive cavern or aquifer, then releasing the compressed air through a turbine to generate electricity on demand. The Stanford team discovered that CAES has the fewest material constraints of all the technologies studied, as well as the highest ESOI value: 240. Two CAES facilities are operating today in Alabama and Germany.

Global warming impact

A primary goal of the study was to encourage the development of practical technologies that lower greenhouse emissions and curb global warming, Barnhart said. Coal- and n
