Musk denounced hydrogen power and ridiculed a billionaire opponent in the same breath.

Yesterday, the hydrogen energy hater casually dismissed Microsoft founder Bill Gates' claim that hydrogen power is the " Swiss Army Knife of decarbonization" by responding to another user's Gates-disparagingtweet with just a simple yet effective laughing.

There are many uses for cheap clean hydrogen. We would be all good if we could bottle the tooth fairy and clone Santa Claus.

Hydro No

There is a deep rivalry between these two tech moguls.

At the Future of the Car Summit, Musk said the resource was the most dumb thing he could imagine for energy storage.

He said that he can't emphasize this enough. Hydrogen is a bad choice if you want to store energy.

There is a public beef between Musk and the hydrogen cell-powered truck manufacturer.

Hydro Hurrah

Gates is excited about the potential of hydrogen energy.

Gates believes that traditional battery power is good for passenger EV and shorter trucking, but not so good for aviation, shipping, and long-distance trucking, for which hydrogen fuel cells might make a lot more.

The philanthropist wrote that clean hydrogen has the potential to be a net-zero solution for moving cargo.

Musk seems to think otherwise, since his company has a battery-powered truck.

When it comes to passenger vehicles, hydrogen fuel cell technology has a lot of work to do.

The drama has taught us that a picture is worth a thousand words.

Musk took a weird picture with the Pope.
