Will iron-air or sodium-ion battery technology achieve a commercially operational grid storage deployment of 100 MWh or more in the U.S. by June 30, 2027?

Resolves July 15, 2027(465d)

IG: 0.48

Resolution Criteria

Resolves YES if by June 30, 2027, at least one iron-air or sodium-ion battery energy storage system of 100 MWh or greater capacity is commissioned and delivering electricity to a U.S. grid interconnection point. Pilot projects, demonstration units under 100 MWh, and non-grid applications do not qualify. Resolves NO otherwise.

Disruption Vector Scanner identifies VULNERABLE exposure with LAGGING adaptation. FEOC restrictions and tariffs force supply chain reconfiguration. Alternative chemistries (zinc-bromine, iron-air, sodium-ion) gain structural advantage if they achieve commercial scale.
