Hello everyone, I am very curious and unsure, today I watched a documentary about Hydrogen and the earlier attempts of a Hydrogen Economy. I am really fascinated! But I don't understand why the Hydrogen Economy always failed. Already in 1874 wrote Jules Verne that hydrogen will replace coal in the future, 100 years later in 1980, after the Chernobyl catastrophe the Hydrogen Economy had a new climax and it failed again, and now researchers shout out again : The Hydrogen Economy start now! - What changed? - Why can the Hydrogen Economy now be successful?
