I get that you are cynical but did you read the linked article? This is a pilot project to see if “green hydrogen” could be a viable option in Europe. Maybe if you followed the news you would realize there is a big push to wean themselves off Russian gas/methane. They are going to try to use water as a hydrogen source and renewable energy because that is a native source of energy.

Maybe realize your cynicism comes from a different kind of marketing. Who benefits when people discount the possibility for change? Oil companies love people like you.
