Yamaha's HYDROGEN ENGINE & Booth 2024 Miami Boat Show

[@engineeringdepartment7961]

ONE SUGGESTION - In order to minimize potential leaks - or worse - a complete sudden blow-off... On all that hard piping that terminates to flare nuts, leave a small spiral / coil of tubing before each connection to act as a shock absorber for the flare fitting connection. Regardles of the hull rigidity, there will be flexing between all those components. You don't want that movement to transfer to those flare fittings.

[@rayzar6720]

That makes sense

[@robertjackson7590]

They should use O Ring seals like auto A/C so for any reason it became loose the seal would still be 100%. For safety sake a sniffer under the cowl that shuts down the main supply valve at the tank.

[@bobbyinalaska.4186]

Shut up Fanni Willis

[@hunterlee6415]

Or use an accumulator

[@cainejarvis2050]

We put the 300HP with the DES on 26ft RIBs and you can turn the boat 90° at 35kts with 1 finger. Pretty impressive system

[@RoadKing65]

As long as it's not a electric engine I'll take it

[@Pleksilasi]

Best way to test if a guy really knows or just seems to know is tangential information. I like how you point out that the fishing lines will catch onto the bubble letters. Great vid, keep 'em coming.

[@BornAgainBoating]

Thank you lol :)

[@AmericanConstellation]

Where can get hydrogen at?

[@rollingrecords9019]

Thanks for keeping us all updated appreciate your videos

[@BornAgainBoating]

For sure!

[@yanassi]

Range? Refueling? Risks? Important questions.

[@mikeknottscreek8183]

Appreciate the tour.

[@BornAgainBoating]

You are welcome! Thank you for watching :)

[@whyme8068]

Torqueedo in a different area?

[@BornAgainBoating]

I didn't see them there this year, they just got bought buy Yamaha, or in the process of being bought by Yamaha, so my guess is they will be in the Yamaha booth next year :)

[@TheSpadre]

The maximum pressure for that tank is 12690 psi.

[@caryralls7488]

Yup and the working pressure is about 10K. Good thing is if it blows you won't even know it.

[@nolanohana]

Fuel cells under pressure have a limited life span, might want to ask about their expiry and provisions for replacement.

[@HermanTheHacker]

The pressure tank is max 20 years. It says so on the tank as shown in the video.

[@ericdavi1231]

The Mythbusters got a car from the junkyard to run on hydrogen in one of their episodes. It’s not a complicated process. The “myth” was that you could run your car on water by separating the hydrogen molecules from oxygen in “H2O”…. The myth got busted because it took just as much energy to separate the hydrogen from the oxygen as you got when you burned the hydrogen in the car.

[@remytavaitai6803]

And you can easy refil in gas station ?

[@MrInsanityflea]

Imagine two strokes making a comeback with Hydrogen! "Optimax H2", sounds great

[@BornAgainBoating]

Interesting, Opti Diesel is a thing soooooo :)

[@robtopham6095]

Wow thanks for the video. The H2 unit is certainly a prototype. I've never seen MPa (Mega-pascals) in anything that was made for the general public. 70 MPa is over 10,000 PSI. That's a serious bomb in the bilge. You'd better think twice about bringing that friend that smokes!

[@nonameHER0]

Thousands of Fuel Cell Cars are incorporating 70MPa Tanks all over the world. Ever heard of something bad happening?

[@robtopham6095]

@@nonameHER0 My understanding of fuel cells is that the hydrogen is not consumed like gas is in an internal combustion engine which (I assume is what Yamaha H2 has made). It's rather like a battery and produces electricity through a chemical reaction using hydrogen and that drives an electric motor. Yes I have heard of hydrogen fires but not under this extreme pressure. To be honest I would love for someone to figure out both production of hydrogen (with our fossil fuels) and safe burning of hydrogen. It's the perfect fuel source. Its byproducts are heat and H2O.

[@bsfishing7073]

Can you imagine what happened when you have a leak on the tank 💥

[@sylvainlessard4552]

there is no Marina provide hydrogène 😢

[@dustin9035]

I didn’t know my Marina has Hydrogen at the pump, sweet!

[@caryralls7488]

i wonder how much electricity it takes to compress hydrogen to 10K psi? and where does that electricity come from before it magically comes out of the wall?

[@BornAgainBoating]

Lol :)

[@jeant10]

There are options on what source electricity can come from. There is only one for where oil comes from.

[@MILITARISTAGGRESSOR]

🤣🤣🤣👍👍👍🤣🤣🤣Зрите в корень! Привет из России!

[@fishingfool2644]

The stainless steel lines would have to be designed to withstand vibrations on the water.

[@BornAgainBoating]

Yeah, idk if this will ever make it to production :/ seems like you'd have to trade all the fishboxes and livewells and storage in the middle of the boat for the H2 tanks

[@Redbird45]

I feel like there’s a lot more that could go wrong with a hydrogen fuel system as as posed to a a normal gas outboard by look at those tanks and all that tubing

[@chiphill4856]

Is it any more dangerous than an aluminum tank filled with volatile gasoline? Which is also bomb.

[@hansgruber2509]

Yes it is by far, corrosion and metal fatigue will make it a nightmare to maintain

[@voodoodaddy574]

​@hansgruber2509 apparently you've never seen a carbon fiber tank.

[@hansgruber2509]

@@voodoodaddy574 You mean like the one the imploded killing all on board in a submersible? Yes they are very reliable. Ok smarty pants do know how they produce H2? It's neither cheap nor energy efficient. I'll stick with my Aluminum tank and gasoline

[@1ricardobaptista]

Yes!!!!

[@UltraMagaFan]

You should learn the difference between something being volatile and something being explosive. Cause unlike gasoline, hydrogen is explosive and far more dangerous.

[@robertm2172]

Here in California we can’t get hydrogen for our vehicles that are hydrogen electric what makes you think this is gonna work

[@BornAgainBoating]

And California is the place with the most, (majority) or H2 stations lol

[@wilsonthesphere]

3x 12,000 psi bombs in my boat no thanks 😂

[@jbbref5564]

you should see what lithium does when it starts on fire.

[@wilsonthesphere]

@@jbbref5564 yeah I heard that lithium fires can get so hot it can melt concrete. Gas and diesel doesn't burn that hot.

[@TrippyWheelz]

Hmm. I can see the benefits even not knowing range. Can see a lot that could go wrong with it too.

[@Gggggh580]

This engine seems to me to be just a marketing campaign, hydrogen as we all know is a highly explosive gas, Yamaha (marine) is an extremely conservative company and I really don't believe it would put a product like this on the market. Hydrogen that is there is not liquid but gaseous as it is difficult to store liquid nitrogen. Does anyone here believe that this bunch of fiber tubes and cylinders can withstand the marine environment for 10 years without risk?

[@Mike-hb4pc]

Aside from all the obvious issues, it’s a neat concept. I wonder where we would be today if the amount of money that has been spent on EVs was spent on hydrogen cars/vehicles?

[@matt1234link]

They should name it The Hindenburg

[@BornAgainBoating]

Lol :)

[@Outdoors-pb2sc]

Bring back 2-strokes!

[@johnboy5167]

Why bring back crappy 2 strokes when modern 4 strokes are so much better

[@Outdoors-pb2sc]

@@johnboy5167 Because old carbureted 2 strokes are easier to work on, I can tune them with a screwdriver. Whereas a new 4 strokes needs an entire computer system to hook up to even look at what is wrong with it. 2 strokes may not be as fuel efficient as 4 strokes but the simplicity of them being easy to use and maintain is in my opinion is why I prefer a 2 stroke. Plus I love the smell!

[@johnboy5167]

@@Outdoors-pb2sc l understand what you are saying l had a yummy 2 stroke for 10 years and it was a good engine but I sold it and got an f 225 Yamaha 4 stroke it was a much better engine had a good run with it for 20 years traded it in recently for a VF 250 sho Yamaha 4 stroke and it is an amazing engine that is far superior to any 2 stroke

[@joenobles1086]

It's showing to fill up a Hydrogen h2 fuel cell $78. To $90. I'll keep my 20hp Mercury I can go further and cheaper with my gas

[@sharonbraselton3135]

Mercy 15 hp elrrtic best

[@roberttrull2525]

What could go wrong

[@Tsgraphix1987]

How is it on gas? 😂

[@UltraMagaFan]

I'm gonna pass on these hydrogen engines. I don't want to be blown up when I'm 50 miles offshore and I can't call 911.

[@gsxr600rafii]

Why would you go that far without a satellite phone as a backup?

[@UltraMagaFan]

@@gsxr600rafii Even with a phone you still don’t call 911. You call the coast guard. And it can take the coast guard hours to get to you. They’re not as fast as paramedics.

[@Tom-lm6sg]

Just imagine. He we need to stop for fuel there is a marina just in past the inlet they have fuel lets fill up the hydrogen tanks. Yes that is it just an imagination!!!!

[@BornAgainBoating]

Lol

[@robertmoody2221]

Looks like a disaster of a motor

[@lon602]

This is the future, not electric. Sorry Elon.😄

[@donbrum2264]

Just a thought but why would anyone want pressurized Hydrogen gas that's extremely explosive on their vessel. I don't believe this was very well thought out. Yamaha stick with Petro its much less explosive and does not have to be put under pressure. BOOM!!!

[@MILITARISTAGGRESSOR]

Хрень. Бомба в мотолодке. Да и энергии будет затрачено на производство водорода и его сжатии намного больше, чем бензина, дизеля. Да и побочек много в двс от водорода, не любит он его. Привет из России!
