Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Commercial Hydrogen is currently produced by cracking oil or natural gas, so it is a derivative hydrocarbon product.

The other method of producing H2 is electrolysis which requires a large amount of electricity, and is cost inefficient. If you need to produce electricity to crack water, why not just use the electricity to power the vehicle?

Having said that, there is maybe a future for H2 in air travel - but the safety issue is horrendous, as is the weight issue for high pressure, or the temperature issue for cryo H2.
