EnerVenue is a start-up attempting to commercialize Nickel-Hydrogen batteries for grid-scale storage. In late March, they announced the construction of a 73-acre "gigafactory" to produce a gigawatt-hour/year of batteries. The announcement claims that the new factory will begin production by the end of the year.

Resolves YES if credible media reports the EnerVenue gigafactory has begun battery production by year end 2023. Resolves NO otherwise. The question may wait for up to 1 month past closing to resolve (or may re-resolve within this window) to account for possible delays in reporting.
