Liquid Batteries: Rethinking Our Power Grid
28 Apr, 2012
Donald Sadoway, the John F. Elliott Professor of Materials Chemistry at MIT, has earned a crescendo of recognition this year for his pioneering work on an entirely new type of battery, one based on floating layers of high-temperature molten metal and salt.
The battery could provide electricity storage on a scale useful to major electric utilities—allowing them to store energy whenever it’s available and cheap, and then pump it back into the grid when it’s most needed. Such storage capability could be the key to making intermittent sources of power—such as sun, wind and tides—a reliable part of the world’s energy supply.
The innovative approach earned Sadoway a coveted spot at this year’s TED talks; a video of his remarks [below] garnered more than 440,000 views in its first three weeks online.
What’s the key to using alternative energy, like solar and wind? Storage—so we can have power on tap even when the sun’s not out and the wind’s not blowing. In this accessible, inspiring talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As he says: “We need to think about the problem differently. We need to think big. We need to think cheap.”
