The question is not battery or hydrogen. It is when.
Batteries dominate the short, frequent, well-aligned load. Hydrogen earns its place across the long, the infrequent, the seasonal. The value is not in either medium. It is in knowing where one hands off to the other.
Hydrogen keeps the season.
Illustrative. The threshold is not fixed — it moves with electrolyser cost, fuel-cell efficiency, load frequency, and capital terms. Locating it for a given project is the work BatteryH2 governs.
A storage decision is a classification, not a preference.
Every storage choice answers a set of governed questions. BatteryH2 names them, scores them, and produces a defensible verdict — so the decision survives an audit, a board, and a financier. Six dimensions define the crossover.
Duration
How long must stored energy hold before it is needed — hours, days, or a season?
Frequency
How often does the cycle repeat? Daily cycling and once-a-year reserve reward opposite media.
Round-trip efficiency
Batteries return ~90%; hydrogen ~35–50%. Efficiency is decisive only when energy is scarce.
Capital structure
Power cost versus energy cost. Hydrogen's cost-per-stored-hour falls as duration grows.
Siting & volume
Salt caverns and geology unlock hydrogen at scale; batteries scale decentrally.
Load alignment
How well does generation match demand in time? Misalignment shifts the threshold toward hydrogen.
A reference layer, not a product.
BatteryH2 does not sell storage. It sits above the vendors, the chemistries, and the marketing — a neutral, governed reference for the one decision every hybrid project must defend.
