One of the most compelling arguments for hydrogen is the impressive gravimetric energy density, carrying over 100 times more energy per kilogram than lithium batteries (~30 kWh/kg vs ~0.3 kWh/kg). This means that flying long distances in battery-electric aircraft with any meaningful payload is extremely challenging, but the right hydrogen architecture could make >1,000 mile routes possible. H3 Dynamics' new modular design enables it to power aircraft with takeoff weights ranging from
