Back On The Grid

Grid Scale Battery Storage

Listen Later

If the grid was Goldilocks, what type of battery would it want? This episode is a bit denser than usual and explores some basic differences between flow, iron-air, and lithium ion batteries; plus the basics of how batteries participate in markets. Also covers some technical stuff towards the end. Listen at your own peril--you may become a flow stan.
