🤺 How competitive is the energy storage market? On this episode, Cofounder & CTO of VoltStorage Michael Peither joins, as always, BioZen's CEO Nate Kirchhofer to discuss this, the size of the need (in TWh), and perspectives on battery development cycles. VoltStorage is a leading manufacturer of vanadium redox flow batteries (V-RFBs) for agriculture and industrial applications requiring "Commercial" batteries (8-12+ hour discharge), and they have also established in-house pilot research in iron redox flow batteries (Fe-RFBs) for so-called "Long Duration" batteries (12-48+ hours discharge) that are critical for integrating renewable wind & solar into grid baseload capacity. The discussion further differentiates VoltStorage from other iron-battery companies ESS and Form Energy: ESS focuses on 12 hour storage, while Form is targeting the 100+ hour markets. VoltStorage's batteries achieve a cost of €70/kWh (~€100/kWh installed), and have 1500X the energy density of pumped hydro, which gives them hope they can capture 10% of the 12-48+ hour storage market.
