Hydrogen outboards

Yamaha has a hydrogen outboard prototype

Nice it’s an hydrogen ice outboard and not a fuel cell for an electric outboard

That's going to be fun filling up at the dock

I guess they have fixed the fuel line seal problem

Hydrogen is not the answer for cars or other smaller motors.

Why? Just wondering why you don't think it's a good option?

Hydrogen is safe, It can be easily produced, It is clean & green, existing engine technology can be used to operate on hydrogen... IMO it is a far better alternative than battery powered electric options.

The only issue they need to solve is hydrogen molecules are so small it’s hard to contain them and to make seals to lines and whatnot that don’t leak

I do agree that hydrogen is a viable solution to a lot of problems.

However, I'm not so sure "safe" is a word that can be used in relation to hydrogen.

Hopefully, things have changed in the last 100 years...

Part of the problem with the Hindenburg was what they used as a coating for the outside of the ship.

Hydrogen is volatile for sure but from what I have read it is safer than gasoline. Both fuels are dangerous if there is a leak and there is enough oxygen with an ignition source. Gasoline being a liquid can be more dangerous if there is a leak because it can spread over an area and remain there for a long time with the possibility of igniting the gas and its vapors while hydrogen leaks and escapes into the air it is dangerous if the concentration of hydrogen and oxygen is high enough along with an ignition source. (Like in the Hindenburg) In fact the Hindenburg's fire was mostly due to the diesel fuel that was used to power the engines and a flammable lacquer on the outside of the ship. There seems to be little concern that hydrogen fuel cell vehicles are more dangerous than gasoline powered cars with internal combustion engines.

my eyes have a hard time reading highlighted text, so I fixed it so I could read it

Thanks Terry,

I apologize for the highlighted text in the previous post, it showed up and I was unable to switch it off.
