Here is an interesting but sad documentary from 2020. (1h40m). It addresses the concerns about hydrogen. "Michael Moore presents Planet of the Humans, a documentary that dares to say what no one else will — that we are losing the battle to stop climate change on planet earth because we are following leaders who have taken us down the wrong road — selling out the green movement to wealthy interests and corporate America. This film is the wake-up call to the reality we are afraid to face: that in the midst of a human-caused extinction event, the environmental movement’s answer is to push for techno-fixes and band-aids. It's too little, too late. " https://www.youtube.com/watch?v=Zk11vI-7czE https://www.youtube.com/watch?v=Zk11vI-7czE
