Innovation in Stationary Electricity Storage

Seminar abstract

Massive electricity storage would offer huge benefits to today’s grid, reducing price volatility, improving stability against loss of power, increasing utilization of generation assets by enabling us to design towards average demand instead of peak demand, and deferring the costs of upgrading existing transmission lines. When it comes to tomorrow’s grid, storage is critical to widespread integration of renewables, i.e., solar and wind, which due to their inherent intermittency present challenges for contribution to baseload. Comprising two liquid metals and a molten salt electrolyte, the liquid metal battery has been invented to offer colossal current capability and long service lifetime at very low cost, i.e., the price point of the electricity market. The round-trip efficiency of these batteries is greater than 75% with a duty cycle of 4 h discharge. Fade rates of 0.0002%/cycle have been measured which means retention of >99% of initial capacity after 10 years of daily cycling and 80% of initial capacity after 300 years of daily cycling

About the Speaker

Donald R. Sadoway is the John F. Elliott Professor of Materials Chemistry in the Department of Materials Science and Engineering at the Massachusetts Institute ofTechnology. He obtained the B.A.Sc. in Engineering Science, the M.A.Sc. in Chemical Metallurgy, and the Ph.D. in Chemical Metallurgy, all from the University of Toronto. The author of over 150 scientific papers and holder of 19 U.S. patents, his research is directed towards the development of rechargeable batteries for grid-level storage and environmentally sound technologies for the extraction of metals. He is the founder of two companies, Ambri and Boston Electrometallurgical. Viewed over 1,500,000 times, his TED talk from February 29, 2012 is a narrative about inventing inventors as much as it about inventing technology. In 2012 he was named by Time magazine as one of the 100 Most Influential People in the World.
