New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

The new battery design could help ease integration of renewable energy into the electrical grid at lower cost, using Earth-abundant metals, according to a study just published in Energy Storage Materials. The new sodium-based molten salt battery uses two distinct reactions. of peak charge capacity. —Weller et al.

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

As the pressure to decarbonize electricity grids mounts, so does the need to have long-term storage options for power generated from renewables. Especially for sources like wind and solar, which have discontinuous availability. He expects the battery to retain over 80% of its charge in that period.

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.). There was no decline in the voltage.
