Hydrogen powered cars and other devices using it were touted as a great way to combat climate change since the only byproduct of hydrogen combustion is water. However, the problem is how to make it, which isn't so green after all, so mankind is still searching for a solution. Quite depressing really.

Physicist Sabine Hossenfelder explains it all in another well researched video.

Replacing fossil fuel with hydrogen seems like an ideal solution to make transportation environmentally friendly and to provide a backup for intermittent energy sources like solar and wind. But how environmentally friendly is hydrogen really? And how sustainable is it, given that hydrogen fuel cells rely on supply of rare metals like platinum and iridium? In this video, we have collected all the relevant numbers for you.
