Batteries aren’t holding back anything. The thinking that batteries are a solution is the hold up.

This article reminds me of those in Popular Science magazine that tout great things that never happen. Like the other commenter mentioned, the article linked to is very old.

it’s two current techs integrated into one. Electrolysis is simple. if you don’t know how it works open a grade school textbook. It’s simply a novel form of two ideas.

This is an important advance (though dated), but it is still water-intensive (fine if you live where water is plentiful)..and, it will require storage of (highly explosive) H and O gases in one’s private residence…still a few bugs there, but on a small scale (and/or with water reclamation), this can have many practical uses

This is referencing an article that is 3 years old… We should be 33% of our way to home energy self sufficiency by now…

You’re clearly not an engineer. Formation of water from hydrogen stores approximately 13.4 kilojoules/gram of water formed. By comparison, reverse hydro storing to a height of 30m (for instance, filling a water tower) stores only .29 kilojoles/gram water.

80% efficient or not, you can store 45 times more energy via electrolysis that reverse hydro storage in a water tower.

I suppose you could store water on top of a 4,429 ft mountain, then it would be the same. However, I imagine your efficiency would drop below 80%.

Yes! This is awesome. the one major thing holding back renewable energy is a good battery. This is a good step.

How is this a new technology? Solar-powered electrolysis is not a new concept…using Hydrogen & Oxygen as an energy carrier for fuel cells is not a new concept…and combining these systems into a sustainable energy loop is not a new concept either. As such, what specific advancements are being discussed here? Is it a new type of Hydrogen storage? Is it a new photovoltaic system?

It is electrolysis but carbon free then run the hydrogen threw a fuel cell and it make more water for the system.

This article is disappointing. Almost no details about the process are described. Call me when you are actually ready to discuss the technology.
