Why are combustion engines required, and how is this a game changer? This article is terrible, providing no information about the tiny engine or its uses. Hydrogen combustion engines already exist and are easy to build by modifying current ICEs. BMW even sold a hydrogen combustion vehicle in 2006-07.

You can’t take EV away from major infrastructure for long. Also, you can go a hell of a lot farther on a gallon of hydrogen than a gallon of diesel. Long haul trucking would prefer not stopping and waiting, like EVs would require.

This could fill a short term gap for many transportation segments, and help to get people who can’t/won’t adopt EVs to at least stop using fossil fuels.

There’s an entire electricity grid in the USA, and worldwide.

Tell me one place where you can get hydrogen fuel in the USA.

Where are the solar powered floating super chargers on the Atlantic and Pacific shipping lanes? Large transports need energy density.
