What the current evidence supports

Human editorial judgment · 2026-09-22

Track; not yet

Why
Genuinely differentiated $/kWh for multi-day storage and a very strong contracted backlog (Google/Xcel 30 GWh, Crusoe 12 GWh), but it is a grid-scale utility product with a low ~40-50% RTE, no at-scale operating record yet, and no direct relevance to a software/commerce ecosystem beyond macro-domain signal.
Next
Monitor the Great River Energy 1.5 MW/150 MWh Cambridge MN project for published round-trip-efficiency and cycle-durability field data once fully operational in 2026
