Flow batteries are ready for prime time

Flow batteries beat lithium ion prices for peaker plant replacements. They have similarly strong economics against diesel gensets in microgrids. To win in the commercial/industrial and utility markets flow must prove bankability and demonstrate a total cost advantage against incumbents. Primus has a clear path to both with a very low material cost, long fade-free life and product/project insurance tools.
