Sodium chloride is a very stable chemical, so will only take part in reactions that require energy to be input. So it will never be an energy source, but an energy storage is possible, just like water.

Once again you failed to watch the video and embarrassed yourself by exposing your ignorance on the matter evidenced in the video. I subsequently researched the method shown in the video and confirmed that it is a possible future source of energy. 


I will give you an opportunity to apologize and retract your statement.

Yes, ionic bonds in molecules are generally difficult to break (require a large amount of energy) because they are so strong. Most rocks have ionic bonds. But, the ionic stability of NaCl is not an impediment to energy production here, Einstein.   

Also, anyone with half a brain knows salt can store thermal energy. That also is not part of this discussion, Mr. Pedant.

What IS part of the discussion is the fact that, by applying a certain RF energy beam to sea water, hydrogen is dissociated and can then be burned.

While it is true that the energy to generate the RF makes this process inefficient, and therefore instantly rejected by people like you, the fact is that a solar panel array, which lasts about 30 years, can make the ERoEI of this process positive WITHOUT any pollution costs. The reason for that is that is simple, though you have a consistent inability to grasp it.

We do not have to generate the photon energy that comes to us from the sun. Therefore, that input, that isn't going away any time soon, is the FREE portion of the Energy Invested (EI). While it is true that, once they have the giant solar arrays in place in the oceans, they may just go the electrolysis route (which is presently a tad more efficient), rather than the RF route to get the hydrogen from sea water, the fact is that RF energy CAN make use of NaCl in sea water as an energy source.

DON'T try to split hairs and claim the energy source is actually hydrogen from the water in the sea water. Yes, the hydrogen is the end product, but an integral part of the process is sea water. It is all discussed in the last ten minutes of the video. Please WATCH IT (go to the 39 minute mark) before you insert your pseudo-erudite foot in your mouth again.


If you do not apologize for your erroneous statement (Palloy: NaCL will never be an energy source), I will delete your post.


Could Giant “Solar Rigs” Floating On the Ocean Convert Seawater To Hydrogen Fuel? 

Scientists at Columbia University have designed a device that could make the process economically viable

SNIPPET:

Usually, when we think about energy production at sea, we imagine giant oil rigs, or perhaps rows of towering wind turbines.  Recently, though, floating solar panels have been added to the mix, including a solar farm the size of 160 football fields that went into operation in China last year.

Now, a team of researchers at Columbia University wants to go a step farther. They say it’s possible to use solar panels on the ocean surface to power devices that can produce hydrogen fuel from seawater.

Hydrogen is a clean form of energy, but it’s most commonly produced from natural gas in a process that also releases carbon dioxide, a key driver of climate change. The Columbia scientists say their device, called a floating photovoltaic electrolyzer, eliminates that consequence by instead utilizing electrolysis to separate oxygen and hydrogen in water molecules, and then storing the latter for use as fuel.

Team leader Daniel Esposito, an assistant professor of chemical engineering, points out that using existing commercial electrolyzers to generate hydrogen is pretty costly. “If you take off-the-shelf solar panels and commercially available electrolyzers, and you use sunlight to split water into hydrogen and oxygen, it’s going to be three to six times more expensive than if you were to produce hydrogen from natural gas,” he says.

He also notes that those electrolyzers require membranes to keep the oxygen and hydrogen molecules separated once they’re split apart. That not only adds to the cost, but those parts would tend to degrade quickly when exposed to the contaminants and microbes in saltwater.

“Being able to safely demonstrate a device that can perform electrolysis without a membrane brings us another step closer to making seawater electrolysis possible,” Jack Davis, a researcher and lead author of the proof-of-concept study, said in a statement. “These solar fuel generators are essentially artificial photosynthesis systems, doing the same thing that plants do with photosynthesis, so our device may open up all kinds of opportunities to generate clean, renewable energy.”

Two mesh electrodes are held at a narrow separation distance (L), and generate H2 and O2 gases concurrently. The key innovation is the asymmetric placement of the catalyst on the outward facing surfaces of the mesh, such that the generation of bubbles is constrained to this region. When the gas bubbles detach, their buoyancy causes them to float upward into separate collection chambers. (Daniel Esposito/Columbia Engineering)

Bubbling up

So, what makes their electrolyzer distinctive? 

The device is built around electrodes of titanium mesh suspended in water and separated by a small distance. When an electrical current is applied, the oxygen and hydrogen molecules split apart, with the former developing gas bubbles on the electrode that’s positively charged, and the latter doing the same on the one with a negative charge.

It’s critical to keep these different gas bubbles separated, and the Columbia electrolyzer does this through the application of a catalyst to only one side of each mesh component—the surface farthest away from the other electrode. When the bubbles get larger and detach from the mesh, they float up along the outside edges of each electrode instead of mixing together in the space between them.
