First boat to make its own hydrogen fuel from seawater
The Energy Observer set sail on a six-year world tour in 2017, testing new technologies, from onboard hydrogen electrolysis to fully-automated sails. It’s hoped the rugged ocean environment will prove the techs’ durability and usefulness at home. #EnergyObserver #Hydrogen #Toyota

Fuel cells. Or as Elon Musk calls them “fool cell”. Joking aside, I believe he makes a good argument against fuel cells. It is less efficient to convert energy to electricity to hydrogen and back again. It is at best a stopgap solution until batteries are lighter. Also batteries usually fizz out rather than deflagrate…

Yep. It’s _game over._ 402 mile EPA range on a Tesla Model S with solar, wind, and hydro everywhere. Tesla recently became the largest car manufacturer by market cap, and Toyota still doesn’t get the message. Anyone with a brain saw this a decade ago.

Hydrogen makes most sense, in my opinion, with large seafaring vessel, where both weight and *space* are at a premium. H² might also be useful in commercial air travel; with both passenger and/ or cargo craft

First .. I love the concept.
As the owner of a sailboat, it has been my experience that complicated devices and the oceans don’t mix well together. Breakdowns in the middle of the pacific can’t be fixed by going to a local West Marine. The more one depends on computers and other electronic devices the greater the risk of failures that could be life-threatening.
Having sails will reduce some of the impacts as at least they can limp to the nearest island.
I hope the sails have manual overrides for those automated systems.
That being said … I do see these prototypes being used in a home. Being able to generate and store hydrogen from excess solar means less dependence on batteries that require rare earth metals that are quickly being depleted. I’d rather store my power than sell it back to the utilities.
Of course, it also means having a bomb in your home, but homes have been exploding from propane for over a hundred years and we still use it. I know I do.

Neat concept, but one of my chemistry teachers told me that the process to release the hydrogen releases CO2 into the air.
William Meyer
July 17, 2020 at 7:30 pm
Only when hydrogen is produced through steam-methane reforming, not electrolysis, which would be how hydrogen is separated from seawater.
Carter Harvey
July 17, 2020 at 8:51 pm
Blue Hydrogen = steam reformation of natural gas.
Green hydrogen = electrolysis of water using renewable energy.
It’s reforming natural gas (a hydrocarbon, ie hydrogen + Carbon) that releases hydrogen and CO2.
Electrolyzing water (h20) releases H2 and O2.

Most people won’t buy H2FC vehicles because they’re massively less efficient and cost effective compared to BEVs.
This is a commercial for Toyota’s H2FC bet.
Consider.. the H2 is generated from excess solar power, at about 50% efficiency.
Or.. that energy could have just been stored in batteries, at about 95% efficiency.
The implication of the ocean wings is that they reduce the energy costs of propulsion for there to be enough spare energy to create H2 while moving. So which would be a better use of that energy? Storing it at 95% efficiency, or using it to store H2 at 50% efficiency.
It’s a whole lot of extra steps to save money on batteries by wasting energy.

If Hydrogen was superior to electricity, it would not require electricity to be feasible. Can you imagine an EV car that required Hydrogen to operate? And Toyota falls behind more and more.

We are creating a problem trying to solve another desalination is not a good thing, specially taking into account the tons of ocean water used for drinking.
We are raising the saline concentration of sea water too much. One ship may not make a big difference but if the tech takes off, there will be fleets of ships and cars. We should stick to solar and wind.
Christopher Carr
July 18, 2020 at 10:58 am
So, hmm, they’re using the solar panels for electrolysis (after charging the batteries),to make hydrogen, to generate electricity from a fuel cell. But doesn’t it take more juice to split water than you get from the resulting amount of hydrogen?
Why not just get bigger batteries?
And are their hydrogen storage tanks lined with graphene or something? Hydrogen really likes to leak through most all things.
David Cox

Batteries are heavy. That reduces range. Converting surplus energy into hydrogen and storing it is a kind of battery. At least this is what I have been reading about it all.

The Conversion from solar to Hydrogen fuel and back to electricity is only about 20% as efficient had they just added more Lithium batteries. Hydrogen fuel cell technology is interesting but is a long way from being more efficient than batteries. The hydrogen fuel cell technology for this application is good as a proof of concept but It is not cost effective or efficient use of space on that craft. It is expensive, in both money and energy, to pry hydrogen loose from other elements, store it, and convert it back to useful energy. The value we get out of it has never quite justified what we invest in producing it. It is one of those technologies that seems perpetually on the verge of a breakthrough, but never quite there. Currently storing electricity in lithium batteries is far more efficient than converting to Hydrogen and back to electricity.

What is it’s sustainable top speed regardless of wind speed? If it can’t outrun a pirate, it needs upgrades.
Doesn’t look like there is much living space on it either. As a proof of concept though, it looks like they have thought of most everything.
Love the H2 energy storage and the 360 degree automated sails!

Sure, because destroying a finite resource (water) is the answer to the energy crisis. Wrong. That burned hydrogen, and ergo water, cannot be replaced so easily. Thank goodness hydrogen fuel cells haven’t caught on! Hopefully that will remain the case.
Renewable energy sources (ie, solar) are clearly the way forward. The sun provides a virtually infinite supply of clean, free energy that can be harnessed to power nearly anything. And fortunately, it is solar that is catching on! Hopefully that will remain the case.

The energy loss of converting water to hydrogen and then hydrogen to water makes it pointless in this applications. Why not just use the solar panels to power the motors…

July 20, 2020 at 6:50 pm
Probably because they are not moving all the time. So when in port they can store the energy as Hydrogen once the batteries are full.
Aloysius Fekete
July 19, 2020 at 3:12 pm
OMG, you mean you have to desalinate the water first? This must be so inefficient. I mean, why wouldn’t you just store the energy in Li batteries? And the boat has batteries anyway so why would you want to deal with the complexity of desalination + electrolysis + H2 storage + fuel cell equipment on top of that? Roundtrip efficiency with batteries is 90%. Must be well below 50% with this setup. Someone please explain why this makes sense?
Nick Arnoldi
July 20, 2020 at 6:41 pm
I agree and would also like to know the numbers behind the conversions. It feels like Toyota just had some extra hydrogen fuel systems laying around and sponsored this idea to try to make the “first” hydrogen fuel powered boat that can travel the globe.
The only upside I can see is you have unlimited potable water on demand in the middle of nowhere from the stored hydrogen.
Aloysius Fekete

Is there a trick to avoid panels stop producing energy when in shade of mast?
From what I know shading even small part of solar panel causes entire panel to not produce energy. That is because individual cells are connected in series.
Or is it just tradeoff – losing power from 20 panels for power of wind?

Hydrogen energy or simply water has been used on modified cars for a while now, but for some reason never improved and just disappear.
Andric Caldor
July 20, 2020 at 7:47 pm
My problem with hydrogen cars is not the absence of refueling stations, it’s the explosive nature of the fuel. If they can mix the hydrogen with something to make it less explosive, I might reconsider it. Also, the energy to put hydrogen into a tank is higher than the energy that is put into the tank. It creates a larger carbon footprint, which needs to be mitigated more.
