Cummins $24 million stake in the startup VoltStorage gives them a foot in the door with new iron redox flow technology. There is nothing wrong with lithium-ion energy storage but global demand for energy storage has nowhere to go but up, and so are lithium prices. While lithium is relatively abundant in the ground, but current supply is falling behind demand. At the same time, lithium extraction is messy and has significant environmental impact, causing local opposition to new mines and other facilities which could stall development. Aside from accessing a recyclable supply chain that can avoid conflict issues, flow battery fans note a long list of advantages over lithium-ion technology including lower cost, longer duration, and ease of scalability

PSR Analysis: Cummins has been making investments into EVs (such as the purchase of Brammo in 2017 and Meritor in 2022) for some time and this low cost, long duration, grid scale energy storage battery is part of their plan. This diversifies their portfolio of alternative power systems and helps them in the gid scale storage market. One of the major advantages for flow batteries is that they aren’t lithium-based and are therefore not subject to the same massive and sustained price increases that lithium material is seeing. PSR
