42.06%

That's 1.03× as thirsty as a truck diesel, while a car diesel is 1.15× thirstier. That is a thermal efficiency of about 42.06%.

What it means

How thirsty is that engine?

Efficiency figures assume diesel at 42.8 MJ/kg. Gasoline holds about 44 MJ/kg and hydrogen 120, so the same g/kWh means different efficiencies for each.

The math

How to convert g/kWh to %

Fuel consumption and efficiency are reciprocals through the fuel’s energy: efficiency % = 360,000 ÷ (42.8 × g/kWh), taking diesel at 42.8 MJ/kg.

Example: 200 g/kWh = 42.0561 %.
