It’s worse than that. 1kg of hydrogen may be 33kWh from a heating value perspective, but it only gets you like 60 miles of range in a car like a Mirai. Compared to a Model 3, which gets 4 miles per kWh, that puts the hydrogen at roughly 15kWh of useful energy. Also, the automotive price of hydrogen is about $13-16/kg in the only place with hydrogen fueling stations in the US, ie Southern California.
