There's value in short-duration lithium batteries for intra and interday cycling, but we've found that multiday storage can greatly reduce the amount of renewables overbuild you typically see in a 100% clean energy scenario.

we pair well with any multi-day (MD) mismatch in electricity supply and demand, whether that's due to renewables reductions, or a general lack of capacity. We pair particularly well with offshore wind. We've done a lot of modeling on the role of MD storage, we find that a mix of durations is best

you bet. We are currently building our first large-scale factory in West Virginia, it will start production next summer. We have ~5GWh of contracts signed, mostly with Xcel, Dominion, Southern, and a couple others.

Hmm, perhaps when Iron-air batteries start becoming more commonplace we shall see some more wind/battery dual deployment then, since they are more suitable for long periods of charging and discharging.
