Yanmar Announces Marine Hydrogen Fuel Cell System

Marinelink.com | July 31, 2023

Yanmar Power Technology has commercialized its marine hydrogen fuel cell system.

The system is initially targeted at passenger ships, work boats, and cargo ships that navigate coastal areas where hydrogen replenishment is relatively easy.

Yanmar participated in the development of Japan’s safety guidelines for hydrogen fuel cell ships and the formulation of a roadmap for the use of hydrogen in the shipping sector. It has also conducted demonstrations on test boats and performed 70 MPa high-pressure hydrogen filling tests.

The system achieves zero emissions of CO2, NOx, SOx and PM. It is low vibration and low noise, and the gas valve unit is built into the system housing, making it easy to mount on the hull. The standard system is rated for 300kW power output and weighs 3 tons...more

Imagine no more diesel or petrol contaminating our harbors and oceans

Here's a 70kW EODev Hydrogen Genset for portable green power, 70,000 watts and barely any noise. Ever hear a 70kW petrol generator? How about a 5kW petrol generator? It's loud. I have one.

An extremely quiet demo of the future of Marine energy. The H2 energy revolution continues in August, 2023

1. It's so good to see...

...all of this progress being made in the non-CO2 commercial market!

With the (fossil fuel industry paid) media black-out on anything that challenges our reliance on fossil fuels, we wouldn't even know anything like this is available if we didn't share it among ourselves.

3. They should just burn the dirty fossil fuels from which hydrogen is made at a thermodynamic loss.

Even though fossil fuels are dirty, hydrogen made from them is even dirtier.

It's a disgrace to push this crap when the planet is in flames.

A Giant Climate Lie: When they're selling hydrogen, what they're really selling is fossil fuels.

4. Wouldnt this cut air pollution though?

If it cuts down on bunker oil particulates in exchange for CO2 at the reformation plant, maybe that is not such a bad trade especially for residents of port areas, as well as the ships crew.

[NNadir]

5. No. It will make air pollution even worse, and drive climate change faster.

As I pointed out, with appeals to the scientific literature, in detail, hydrogen is not primary energy, never has been and never will be.

Once again:

A Giant Climate Lie: When they're selling hydrogen, what they're really selling is fossil fuels.

I showed that to make 10 Exajoules of Hydrogen, it is necessary to consume about 20 Exajoules of dangerous fossil fuels, dumping the waste directly into the planetary atmosphere.

Except for the dishonest portrayal - appealing to popular nonsensical belief that the unsustainable and useless wind and solar industries are "green" - in reality more than 98% of the world's hydrogen is made from dangerous fossil fuels by reformation, and the trivial remainder is made from electricity generated by the combustion of dangerous fossil fuels. The exergy destruction I calculated for reformation (by appeal to the literature) was 47.36%, meaning to make 90.2 million tons of hydrogen, with an intrinsic energy value of 10.8 Exajoules (on a planet consuming annually around 630 Exajoules each year), 20.6 Exajoules of dangerous fossil fuel energy is consumed.

The Potemkin "renewable energy" plants that the fossil fuel salespeople and salesbots here and elsewhere hype with extremely dishonest "bait and switch" "green hydrogen" bullshit, are meaningless. I showed that they produce 0.37% of the world's hydrogen, and that electrolysis is even dirtier than thermal reformation, with an exergy destruction of 66.94% overall.

Electrolysis from electricity wasted to make hydrogen from clean nuclear energy was roughly equivalent to the solar and wind generated combined.

Hydrogen is generally not produced for all the cartoon shit video commercials posted here, hydrogen trucks, hydrogen cruise ships, hydrogen cars, line of dishonest bull after line of dishonest bull. The bulk of the world's hydrogen is used in the Haber Bosch ammonia synthesis process on which the world's food supply depends with 8 billion people on the planet. This is followed by the use of hydrogen to refine petroleum, and lastly to manufacture the solvent, window washing fluid component, (and more rarely fuel) methanol.

As for the world food supply, it is now threatened by extreme weather, extreme heat, extreme droughts, extreme floods, extreme, extreme, extreme.

These extremities were driven by th extreme salesmanship of the dangerous fossil fuel industries which has worked for half a century to convince gullible radiation paranoids that nuclear energy was "too dangerous" and climate change wasn't "too dangerous."

And of course, there was the exergy destroying marketing ploy of selling dangerous fossil fuels by rebranding them as "hydrogen."

Guess what? Floods, famines, the destruction of vast stretches of precious and irreplaceable ecosystems, the deaths from air pollution and now from extreme heat were not less dangerous than the big boogeyman at Fukushima.

I hold antinukes responsible for this outcome.

Ignorance kills not only people. It's killing the whole damned planet.

History will not forgive us; nor should it.

6. but it would eliminate toxic air pollution in favor of nontoxic CO2, bad as that is

getting rid of particulate air pollution and all the toxic shit that burned bunker oil spews out would seem to be a laudable goal for the shipping industry.

Of course CO2 is bad but at least its a nontoxic gas despite its heat trapping properties. It wont give you cancer for example.

[NNadir]

7. Moving pollution and making more pollution in doing so is not clean; it's filthy.

It's a three card monte game with the future of humanity as the losing party.

CO2 is toxic. It's killing the whole fucking planet, which is burning.

I really, really, really, really can't believe this line of thinking is not obviously an exercise in horror.

When one hears these sorts of things, one understands exactly how we came to this outcome, that such a thing can even be thought seriously.

[Blues Heron]

8. It's not toxic like particulates or cancer causing substances in bunker fuel exhaust

Which this replaces. CO2 is bad because of its heat trapping, not because it’s toxic.

This would improve the health of the workers and residents of the port cities.

[NNadir]

9. I personally do not value bourgeois cruise people over people who will be killed near chemical...

...plants.

It is not the case that rich people should be allowed to kill poor people for a shell game played by people who just don't give a shit about the future of humanity.

Fossil fuels produce particulates and toxic compounds wherever and whenever they are used. This includes when exergy is destroyed and fossil fuel use is increased to make hydrogen.

Moving pollution from a ship serving the rich to areas in which the poor live, and making more pollution for an idiotic affectation is an example of the contempt for energy justice.

It's disgusting, really disgusting, this awful argument.

Most of these chemical plants are located in areas where poor people live. Making more particulates because rich people couldn't care less about the humanity of poor people strikes me as appalling, but a lot of the bourgeois crap that flies around here, the extreme ignorance, the indifference is no longer surprising.

I do know that antinukes in general have a very low understanding of science, and a very withered moral purview, but this particular line strikes me as classic, even for this awful set.

10. its for work boats and cargo ships not just cruise ships

I think it will make less particulates than burning bunker oil in a ships engine.
