MIT team improves liquid metal batteries for grid-scale storage; lower operating temperature, cost

Green Car Congress

Professor Donald Sadoway and colleagues have already started a company, Ambri (initially Liquid Metal Battery Corporation), to produce electrical-grid-scale liquid batteries, which comprise layers of molten material which automatically separate due to their differing densities. Earlier post.). —Donald Sadoway. Burke, Dane A.

The conference, hosted in Dallas by the U.S. Chilldyne optimized the cold plate using corkscrew-shaped metal channels, called turbulators, that force water around them “like little tornadoes,” maximizing the heat absorbed, says Harrington. Emrgy’s timing takes advantage of the groundwork laid by the solar power industry.

How to Prevent Blackouts by Packetizing the Power Grid

Cars That Think

That need for balance is true of electric power grids, too. Second, conventional coal and nuclear plants are being retired for economic and policy reasons, removing stable sources from the grid. Packetized energy management (PEM) allows the power grid to flexibly handle a varying supply of renewable energy. Here’s how.

DOE announces achievement of SunShot goal, new research focus; $82M in two new solar power opportunities

Green Car Congress

In conjunction with the annual Solar Power International conference, the US Department of Energy (DOE) released new research showing that the solar industry has achieved the 2020 utility-scale solar cost target set by the SunShot Initiative. Solar energy currently supplies about 1.5% of US electricity.
