Researchers have come up with a new system that turns seawater into hydrogen fuel—a development that could aid in the proliferation of hydrogen fuel cell vehicles.
The new method extracts hydrogen from the ocean by funneling seawater through a double membrane system, using electricity. The design was successful in generating hydrogen gas without the accompaniment of large quantities of harmful byproducts.
Vehicles with hydrogen fuel cells are fed with compressed hydrogen gas. The fuel cells do not burn this gas. Instead, cells transform the chemical energy of the fuel into electrical energy, which then powers the vehicle’s electric motors. The only byproduct is pure water, with zero tailpipe emissions.
“Many water-to-hydrogen systems today try to use a monolayer or single-layer membrane. Our study brought two layers together,” said Adam Nielander, an associate staff scientist with the SUNCAT Center for Interface Science and Catalysis, a SLAC-Stanford joint institute, according to an April 11 news release.
“These membrane architectures allowed us to control the way ions in seawater moved in our experiment,” he added. Results of the study were published in the Joule journal on April 11.
The Double Membrane System Researchers tested out their double membrane system using electrolysis—a method that uses electricity to drive ions to run a desired reaction. The most harmful element to the seawater system is chloride, says Joseph Perryman, a SLAC and Stanford postdoctoral researcher.
“There are many reactive species in seawater that can interfere with the water-to-hydrogen reaction, and the sodium chloride that makes seawater salty is one of the main culprits,” he said.
“In particular, chloride that gets to the anode and oxidizes will reduce the

That's sane, rational, and logical.
Therefore, Leftists oppose it.
It looks like those owning beach front property, a hose and a bucket will be the next billionaires. LOL!
Shhhh! You’re not supposed to notice that, or ask questions about it!
What’s the efficiency of the end to end system and how does that compare to the efficiency to taking oil from the ground refining it into gasoline and delivering it at the gas pump?
Soo, THIS is OK, but desalinization isn’t. OK, got it.
This assumes the allowing Americans the freedom to travel outside their neighborhood doesn’t violate the Deep State plan....
They’d have all of the salt 🧂🧂🧂 they’d ever need!!
In the last two months, I have seen like 25 articles or TV reports on new miracle technologies that will help replace carbon based energy.
All of it is pie in the sky political propaganda.
If they only had cells huh some air lines are testing hydrogen fuel zero problems.
EV junk yards are the future France has a huge one.
It's no earth-shattering discovery that hydrogen can be separated from water (it is, after all, H2O), the crux of the biscuit is, how much does it cost, and how much pollution does the process create.
Thew article does say, the method "...extracts hydrogen from the ocean by funneling seawater through a double membrane system, using electricity...." And since the single greatest source of power generation in the US is coal-fired steam plants, that makes this coal and/or steam-powered hydrogen.
The only relevant questions, questions that the article goes nowhere near addressing, is "How much?" How much does it cost, and how much pollution is created in its name.
No matter how you make the hydrogen you still have to contain it in a heavy pressure vessel
That pressure vessel constitutes a danger of fire and explosion in a motor vehicle accident.
Compared to a gasoline vehicle the BTU/lbs hydrogen vehicle is far better which means more miles/lbs.
The hydrogen car is going to have a greater dry curb weight because of the heavy fuel container.
My Opinion is that any electric car starts with a disadvantage simply because of the weight of the fuel storage container.
Battery or pressure vessel; the extra weight is an unnecessary burden when gasoline is easily available and cheap.
Conservation of energy be damned!
True. But if you have to keep burning coal to get hydrogen you haven’t gained anything.
on subs we use nuclear power to split the atom using electricity.
It’s not the generation of hydrogen which is the issue.
It’s the storage of it that poses a technical challenge, i.e. cost vs. safety.
There are technical solutions to make it safe, but those make the cost skyrocket.
To date, regardless of the sales pitch, nothing beats gasoline and diesel specific to cost, safety, practicality (storage, start time, ambient temperature range, pollution) and energy density.
Theoretically, a turbine would be far better than a conventional Otto engine. Turbines are factually more efficient.
But even there you have a lot of problems, exhaust heat, start up time, the engine doesn’t like to vary it’s speed or run slow but would rather just go balls to the wall all the time (turbines like to run close to their limit).
All solutions other than the diesel or otto engine carry with them some serious drawbacks which make them less desirable overall, IMHO.
Sadly, the diesel which is a bit more efficient than the otto engine has gotten a bad rap, but is actually extremely clean today. In fact, if you look at the efficiency of most of these otto and diesel engines and how clean they have become, it’s actually quite impressive.
But, someone decided to label a lithium battery powered car with the green tree goddess seal of approval. Electric = green, and because folks today are like Pavlov’s dog, conditioned to drool as soon as they hear the term green, there is no more debate, even though these cars come with their own laundry list of environmental and even social issues.
Kill two birds with one stone by transforming the rising sea water from “da global crisis” into fuel for our hydrogen cars. Doesn’t get any better than that and Algore and Obonzo won’t have to worry about their mansions going Atlantis on them.
correct
The atomic reaction is self-powered.
” Where does the electricity come from? “
Good intentions and gullibility.
And the problem of storing the world’s smallest atom without leakage is managed by good old magic.
And love. Lots of love.
But mostly Moral Superiority.
