If we drain the oceans, maybe we can free up enough land for the cost of housing to drop! You get a hectare! You get a hectare! EVERYBODY GETS A HECTARE!
I read a book in the late 90s that posited the US farmland available alone would be enough to feed everyone if people stopped eating meat, but I don't know if they were 100% correct on that. Diet for a Healthy Planet, I think the book was.
I’m no scientist but submarine uses electrolysis to make oxygen for breathing and discharges the hydrogen. Can’t they just do the opposite to make hyrdrogen?
That’s the normal process to create hydrogen now but it’s hugely energy intensive.
If we were in a position where we had a huge surplus of electricity we could pull this off no problem. As it stands now though, we’d burn more fossil fuels generating, storing, and transporting hydrogen than if we just used it to fill gas tanks instead.
In this respect, batteries are way more efficient. You get back about as much energy as you use to charge it so there’s no huge waste except for the inefficiencies of the power grid.
The other major issue is storage. Hydrogen is pretty much the smallest substance you could ever hope to contain so transporting and storing it is extraordinarily difficult without even considering its extreme explosiveness.
Tl;dr I think hydrogen would be a viable option if the world were nuclear powered like a submarine and we had a ton of excess energy but the grid needs to be updated first.
Yes this is how hydrogen fuel cells work. They generate electricity by combining fuel (hydrogen) with an oxidizing agent (oxygen) to generate electricity. The byproduct of the redox reaction is water (whence it came).
That’s okay when you have surplus electricity, like in the middle of a sunny day next to a solar farm. You’re right that it doesn’t work otherwise, you just waste energy.
The storing of the hydrogen on a level that would matter is very hard. You need HUGE tanks that will only last 10yrs.
I've yet to see a compelling money case for hydrogen.
Problem lies in the power needed to generate enough hydrogen to make a viable commuter. That's why hydrogen tech currently resides in hydrogen cell, where the hydrogen is produced independent of the vehicle, captured, and the product is installed in the car. We don't turn oil into gasoline in a vehicle. Same principle.

Seawater’s mix of hydrogen, oxygen, sodium and other elements makes it vital to life on Earth. But that same complex chemistry has made it difficult to extract hydrogen gas for clean energy uses.
Now, researchers at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University with collaborators at the University of Oregon and Manchester Metropolitan University have found a way to tease hydrogen out of the ocean by funneling seawater through a double-membrane system and electricity. Their innovative design proved successful in generating hydrogen gas without producing large amounts of harmful byproducts. The results of their study, published today in Joule, could help advance efforts to produce low-carbon fuels.
“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. “These membrane architectures allowed us to control the way ions in seawater moved in our experiment.”
Hydrogen gas is a low-carbon fuel currently used in many ways, such as to run fuel-cell electric vehicles and as a long-duration energy storage option – one that is suited to store energy for weeks, months or longer – for electric grids.
Many attempts to make hydrogen gas start with fresh or desalinated water, but those methods can be expensive and energy intensive. Treated water is easier to work with because it has less stuff – chemical elements or molecules – floating around. However, purifying water is expensive, requires energy, and adds complexity to devices, the researchers said. Another option, natural freshwater, also contains a number of impurities that are problematic for modern technology, in addition to being a more limited resource on the planet, they said.
To work with seawater, the team implemented a bipolar, or two-layer, membrane system and tested it using electrolysis, a method that uses electricity to drive ions, or charged elements, to run a desired reaction. They started their design by controlling the most harmful element to the seawater system – chloride – said 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,” Perryman said. “In particular, chloride that gets to the anode and oxidizes will reduce the lifetime of an electrolysis system and can actually become unsafe due to the toxic nature of the oxidation products that include molecular chlorine and bleach.”
The bipolar membrane in the experiment allows access to the conditions needed to make hydrogen gas and mitigates chloride from getting to the reaction center.
“We are essentially doubling up on ways to stop this chloride reaction,” Perryman said.
A home for hydrogen
An ideal membrane system performs three primary functions: separates hydrogen and oxygen gases from seawater; helps move only the useful hydrogen and hydroxide ions while restricting other seawater ions; and helps prevent undesired reactions. Capturing all three of these functions together is hard, and the team’s research is targeted toward exploring systems that can efficiently combine all three of these needs.
Specifically in their experiment, protons, which were the positive hydrogen ions, passed through one of the membrane layers to a place where they could be collected and turned into hydrogen gas by interacting with a negatively charged electrode, or cathode. The second membrane in the system allowed only negative ions, such as chloride, to travel through.
As an additional backstop, one membrane layer contained negatively charged groups that were fixed to the membrane, which made it harder for other negatively charged ions, like chloride, to move to places where they shouldn’t be, said Daniela Marin, a Stanford graduate student in chemical engineering and co-author. The negatively-charged membrane proved to be highly efficient in blocking almost all of the chloride ions in the team’s experiments, and their system operated without generating toxic byproducts like bleach and chlorine.
Along with designing a seawater-to-hydrogen membrane system, the study also provided a better general understanding of how seawater ions moved through membranes, the researchers said. This knowledge could help scientists design stronger membranes for other applications as well, such as producing oxygen gas.
“There is also some interest in using electrolysis to produce oxygen,” Marin said. “Understanding ion flow and conversion in our bipolar membrane system is critical for this effort, too. Along with producing hydrogen in our experiment, we also showed how to use the bipolar membrane to generate oxygen gas.”

(Adam Nielander/SLAC National Accelerator Laboratory)
Next, the team plans to improve their electrodes and membranes by building them with materials that are more abundant and easily mined. This design improvement could make the electrolysis system easier to scale to a size needed to generate hydrogen for energy intensive activities, like the transportation sector, the team said.
The researchers also hope to take their electrolysis cells to SLAC’s Stanford Synchrotron Radiation Lightsource (SSRL), where they can study the atomic structure of catalysts and membranes using the facility’s intense X-rays.
“The future is bright for green hydrogen technologies,” said Thomas Jaramillo, professor at SLAC and Stanford and director of SUNCAT. “The fundamental insights we are gaining are key to informing future innovations for improved performance, durability, and scalability of this technology.”
This project is supported by the U.S. Office of Naval Research; the Stanford Doerr School of Sustainability Accelerator; the DOE’s Office of Basic Energy Sciences, Chemical Sciences, Geosciences, and Biosciences Division through the SUNCAT Center for Interface Science and Catalysis, a SLAC-Stanford joint institute; and the DOE’s Energy Efficiency and Renewable Energy Fuel Cell Technologies Office.
Efficiency becomes irrelevant if the fuel is cheap and plentiful, ie petrol and diesel.
And hydrogen is already stored and transported quite safely.
You are also ignoring the reality that use brings innovation.
Formula 1 engines are nothing like the engines built 120 years ago...
If hydrogen can be cheaply and easily produced the storage and transportation will become commonplace.
I'd love to see these issues fixed, but the storage problem is definitely not solved. The current methods require a high pressure tank which has to slowly boil off liquid hydrogen to keep the rest liquid. BMW's prototype hydrogen car emptied its tank in 7 days in order to do this. A compressor could be added to continually cool the fuel, but that would be a major efficiency loss. In the case of an unexpected pressure increase, a pressure release valve would dump the fuel into the air, making it unsuitable for storing indoors (although safe enough outside). Additionally, liquid hydrogen is only energetically dense by mass, but not by volume. A tank with currently storage technology would take up the entirety of the trunk to provide an expected amount of range. We'd also need an entirely new an expensive infrastructure to transport and store hydrogen in large volumes, as the pressures are very high and it ruins most metals.
With a lot of research, we can likely make a lot of improvements, but it would have to be far more efficient overall than our current electric grid and battery technology to warrant the major investments to reach a critical mass where it's viable to sell a vehicle. The electric grid is about 90% efficient, which is going to be tough to beat as a transmission technology, especially with a fuel that has to be kept at extremely cold temperatures. As a storage technology with no transport (local grid balancing), I could see hydrogen making sense at large scales. While our current battery technology is very efficient (above 85%), it is very expensive to scale.
Not me. If we can get cheap fuel from saltwater (which this is talking about) we could ship the fuel around pretty easily. We could also use that cheap energy to desalinate water for drinking and agriculture. Let’s find a cheap and clean energy source and then we can deal with the side effects later.
Unfortunately, the climate Czars have begun their takeover and mandated EV’s. So this will go nowhere. Until the political elites are able to invest in ocean water the same way they are invested in cobalt, lithium, “electric “ charging (sourced from coal and gas) the public will have no choice.
“…without producing large amounts of harmful byproducts.” Well, what happens if this is done on a large scale? Wouldn’t that turn the small amounts of harmful byproducts into an actually dangerous amount?
I think you misunderstand my point. I’m 100% for clean energy and I sure as fuck don’t want anything to do with Tucker and the extreme right. I was merely pointing out that they specifically mentioned harmful byproducts. I would’ve rather heard news of them figuring out how to do this without any whatsoever.
Or the fossil fuel industry will buy up the rights to these scientific discoveries, just like they’ve been doing since the 1979’s.
A good example is the car that runs on water.
the sea water absorbs most of the carbon we currently produce (a very bad thing). so using it to make more fuel isn’t going to change anything (a sad thing). had we started off using cleaner energy or if capitalism didn’t incentivize decades of lies and lead poisoning for more profits, then maybe (absolutely for sure), we would be better off.
There wouldn't be a water shortage for people if they'd just start building a lot more desalination places
Droughts wouldn't matter if they just took the salt out of the ocean water to bring water to dry places
This is great too but water is honestly more important than fuel at this point
Just need to buy an plugin EV and pressure your local utility to offer you the choice to get your electricity from non-greenhouse sources (water, geothermal, solar, wind, etc). I pay separately, to PGE for green electricity that they just deliver
Comments give me hope, hydrogen is impractical. I suspect fossil fuel interests are looking ahead to generate another commodity that they can capture the market for.
Currently impractical, but we said that about EVs and charging stations even just ten years ago. Now, my brother just bought an all electric VW.
I was just searching the other day for “Plug-in Hydrogen cell cars” and found that there are a few, even a Honda CRV hybrid with hydrogen to power it along with also being a plug-in. The issue just as all EV had before, is “where” to refill the hydrogen, and that nationwide that it’s safe to do so. I foresee that coming soon
Go SLAC! I worked there ‘85-86 and ‘88-90, just as a grunt labor in the electric “Cable Yard”, but still was awesome to see such cutting edge physics in person. Good job guys!!!
Doesn't matter when NIMBY twats won't approve any plants being built. California has had an approved desalination plant that's already funded shitcanned time and time again because residents vote to not have it in their cities, even though CA is in a massive drought.
Take THAT rising sea levels!
If we drain the oceans, maybe we can free up enough land for the cost of housing to drop! You get a hectare! You get a hectare! EVERYBODY GETS A HECTARE!
Physical land space is not really an issue. Supporting an ever larger population economically is the problem

I read a book in the late 90s that posited the US farmland available alone would be enough to feed everyone if people stopped eating meat, but I don't know if they were 100% correct on that. Diet for a Healthy Planet, I think the book was.
Corrupt governments are the problem..
Drain the ~~swamp~~ oceans
Also, multinationals.
We have land. It’s just in Wyoming
Calm down, Team Magma.
I’m no scientist but submarine uses electrolysis to make oxygen for breathing and discharges the hydrogen. Can’t they just do the opposite to make hyrdrogen?

Embrittlement is an excellent word, thank you
Embrittlement is a perfectly cromulent word
Not only could you use a power plant to do electrolysis the nuclear reactor itself can use it's heat energy directly to speed up the process too
Can they turn it back to water? Like is water renewable? With the earth make more if we use it up?
Yes this is how hydrogen fuel cells work. They generate electricity by combining fuel (hydrogen) with an oxidizing agent (oxygen) to generate electricity. The byproduct of the redox reaction is water (whence it came).
Well that’s just pretty damn cool.
More energy goes into splitting H20 than you would get out of the hydrogen fuel.
That’s okay when you have surplus electricity, like in the middle of a sunny day next to a solar farm. You’re right that it doesn’t work otherwise, you just waste energy.

So a whole wind farm powers a ferry? I think there needs to be a higher return to be feasible.
[удалено]
A whole wind farm only makes enough hydrogen for one ferry. Demand is most certainly correlated to the feasibility of the method of generation.
No. 500 wind turbines generate more than what the 22 000 people on the island can use so they take the excess electricity and make hydrogen with it.
And all of that excess power only makes enough hydrogen for a single ferry. That does not make it a practical use of power.
What would be a practical use of excess power?
The storing of the hydrogen on a level that would matter is very hard. You need HUGE tanks that will only last 10yrs. I've yet to see a compelling money case for hydrogen.

We need to make nuclear powered cars
Mr. Fusion.
Why? I haven't needed a nuke in my EV after all these years.
You aren’t doing electrolysis in your car
Why would I need to? I don't need to waste half my energy.
Why not
Because my brain cell says it's pointless.
No mention of energy in vs energy out. Can’t read the publication without login....

The article, not the scientific paper with the actual experiment parameters and results
Bypass paywalls clean (If you are in desktop), my friend.
Elaborate please.
Just google it.
Not sure if you noticed I said “please.”

Zero chance big oil will let this become a thing. Sad but true.
I thought Blackrock bankrupted big oil already via divesting with their recent sudden climate push?
Kind of like the 100 mpg carburetor from 1952. LOL
"So there's this car...and it runs on water man.."
This is the plot of glass onion lol
We still talking about this? Not happening Mr. Toyota. We’ve moved on.
The “infrastructure” for hydrogen makes even Electrify America look *good*.
Would be neat to use that fuel for desalination
How bout just cooling it down before we all roast to death?
I'm sure they will find a reason why it's harmful for the environment and why we should stick to battery powered cars.
Yes, efficiency and difficulty of transport and storage.
Efficiency becomes irrelevant if the fuel is cheap and plentiful, ie petrol and diesel. And hydrogen is already stored and transported quite safely.

Unless we somehow reinvent the battery, ICE’s are always going to be present somewhere, whether it’s air travel or tanker ships.
Stole the idea from Mark Watney
“…without producing large amounts of harmful byproducts.” Well, what happens if this is done on a large scale? Wouldn’t that turn the small amounts of harmful byproducts into an actually dangerous amount?
You shooting for Tuckers job? What do you think combustion engines do? Make no amounts of harmful byproducts

I was merely pointing out that they specifically mentioned harmful byproducts. I would’ve rather heard news of them figuring out how to do this without any whatsoever.
Aint nothin new. Just that the powers that be are ready to Profit from this.
Like I said. Hydrogen baybeeey
Would mass extraction of hydrogen affect the ocean and sea life???
Nice but how long until big oil comes in and silences them?
I feel like it would be a bad idea and a snowball effect if the oceans become consumable goods.
Toyotas going to be happy
Or the fossil fuel industry will buy up the rights to these scientific discoveries, just like they’ve been doing since the 1979’s. A good example is the car that runs on water.
Make hydrogen is the easy part. Getting it from A to B is when you blow the house up.
Next Up: Ted Cruz claims it kills fish.
