GWH - Tesla Lithium And Emerging Flow Batteries: Sky's The Limit For Grid Applications

• Grid scale battery storage currently rests largely on lithium batteries with Tesla a major player.
• Can lithium batteries be scaled up for all of the emerging uses? They're best for transport and 0-4 hour grid storage.
• There's a role for redox flow batteries in stationary applications. It's early and the best chemistry is not clear, but iron, zinc and vanadium flow batteries look interesting.
• Several emerging public companies are selling flow batteries with MWh levels of performance and 4-12 hr duration. This gets interesting.
• Tesla is a major force for both transport and stationary battery applications, but there are some emerging companies in the flow area worth watching for the 4-12 hour window.
