In this podcast Chris Beekhuis of Gridtential talks to Alix Paultre of Power Systems Design about grid-level energy storage and the issues around the storage methods involved. Gridtential has developed a proprietary technology for an advanced lead-acid battery that replaces the metal grid in current lead-acid battery designs with a silicon substrate. The Gridtential technology yields higher energy density, longer cycle life and deeper depth-of-discharge than incumbent products. The manufacturing of the silicon substrates leverages existing high-throughput, cost-effective solar cell processing equipment.
