Hydrogen vs Battery: The Weight Crossover

Battery packs and hydrogen tanks both grow with required range, but at different rates — drag range, vehicle class and battery density to find where hydrogen's lighter fuel finally beats a battery's fixed-overhead-free but energy-thin pack.

Two glowing curves rise across a 3D grid — one for a battery pack, one for a hydrogen tank-plus-fuel-cell system — both plotted against required driving range for the selected vehicle class. A marker rides each curve at your chosen range while two towers on the right show the exact masses side by side. Because hydrogen pays a fixed stack penalty but climbs slowly, and batteries pay nothing upfront but climb steeply, the curves cross: short-range missions favor the battery tower, long-range heavy missions favor hydrogen. Drag the range and battery-density sliders, switch vehicle class and storage type, and watch the crossover marker — and the verdict banner — move.
