the electricity has to be generated somewhere. coal plants - pollution. hydropower plants - pollution. you might say hydropower plants don’t produce pollution, but it takes a lot of energy to build them and they pollute the environment with their mere existence, no more pristine nature.

You’re explaining how electrical power generation can cause pollution, not water electrolysis (what is being discussed).

[ecoled_ame]

yes indeed i am, because they are related. electrolysis utilizes electricity. hence the prefix electro-.

your point highlights my initial point about hydrogen fuel - ie we must look all the way up the chain and account for all polluting steps, instead of simply focusing on a single aspect.

This is absolutely correct.

Here’s the Wikipedia entry on the subject: life-cycle greenhouse gas emissions - https://en.wikipedia.org/wiki/Life-cycle_greenhouse-gas_emis...
