Without room temp superconductivity solar is a waste. Storage is too expensive. 15% efficiency in hydrogen gas production is very interesting. The residential sector accounts for 22 percent of energy consumption in the U.S., if energy used to generate and transmit electricity is included.

Eliminating 60% of residential energy needs (Heating cooling and water heating) frees up a lot of energy for other uses. I could give a damn about the green thing but this is interesting.

[Lonesome in Massachussets]

We did that in high school chemistry.

Do I want to use hydrogen to heat my house? Do I really need to be that warm?

[Telepathic Intruder]

The problem as always is that solar power is a limited source of energy, and it takes up acreage. It can never replace fossil fuels. Same with wind. When bubble-headed politicians like AOC talk about “renewable energy”, there’s a reason they aren’t specific on what that means. There are none which will meet society’s demands.

[P.O.E.]

Sunlight used to create carbohydrates out of carbon dioxide and water.

[PTBAA]

Given that hydrogen is a gas, isn’t providing a volume without a pressure meaningless?

[stormhill]

That's all very interesting.

But consider the fact that one gallon of gasoline contains more hydrogen than a gallon of....hydrogen!

Of course, some will object that "fossil" fuels have that awful carbon foot-print which causes global warming. Yeah, that's a hoax.

“Using our expertise in this area, we were able to develop a system that is very efficient in taking water from the air and splitting it into hydrogen by using solar energy,” Bosserez wrote in an email. Asked about some of the engineering challenges they faced during a decade of development, he says, “The most difficult part is getting the water out of the air.”

On the one hand, dry desert areas tend to get lots of sunlight.
On the other hand, cloudy wet areas have lots of accessible water in the air.

They just need to find a wet desert and they will have everything they need for theory to meet practice.

Burning hydrogen produces the green house gas water vapor

[Mrs. Don-o]

I've always been interested in clever tech, and this is fascinating. I read with smiles!

Thank you for posting this. LTBM!

[Phillyred]

If it is successful and cheap eventually...meaning -good for the USA -the democrats will destroy it.

re: “Hydrogen, unlike fossil fuels, doesn’t produce greenhouse gas emissions “

Au contraire!

WV (water vapor) is one of the BIGGEST GHG (green house gases) on the planet!!!!

[philman_36]

A team at Katholieke Universiteit Leuven, or KU Leuven, says it has developed a solar panel that converts sunlight directly into hydrogen using moisture in the air.

Just wait till it's announced that electricity can be produced from the air (aether) for free as well.

Talk about true independence from utility companies!
Or is that a step too far down the conspiracy theory trail?

re: “ I could give a damn about the green thing but this is interesting. “

You might be interested, then with what is called the Hydrino, and what that means in terms of producing energy.

But, be advised ... wikipedia does not do this subject justice.

This talk given by a Dr. Randell Mills might be a place to start:

“existing heating fuels such as natural gas are relatively cheap. However, as countries work to address climate change, and as more communities install local renewable energy infrastructure like rooftop solar, he sees a potential role for these hydrogen systems.

The ‘however’ part means that nat-gas is cheap now, but that the green-weiners want to make it expensive enough to for their Unicorn-fart machine to compete.

[HighSierra5]

The big question is .... How much does it cost? Money is a big factor.I guess that the cost would come down after it became widespread.

[yesthatjallen]

Clean?

Inexpensive?

Efficient?

Inexhaustible?

Safe?

I'm all for innovative breakthroughs.

I hope the technical advances continue and everyone can benefit.

[Delta 21]

So in comparison, the methane produced by farting cows is a wash and the government just is trying to push the blame onto us for using food and energy that already has a neutral carbon footprint?!!?

[I want the USA back]

Forget about using hydrogen to cook, power cars, or to heat. Hydrogen doesn’t like to be contained, and loves to escape through even the tiniest of holes, leading to a fire hazard.

In order to use it in a car or for any other purpose, you have to store it at high pressure, making it even more likely that the hydrogen will escape through tiny holes.

[norwaypinesavage]

"The solar panel measures 1.65 meters long—roughly the height of a kitchen refrigerator, or this reporter—and has a rated power output of about 210 watts. The system can convert 15 percent of the solar energy it receives into hydrogen."....."a well-insulated Belgian house could use about 20 of these panels to meet their power and heating needs during an entire year"

There is something terribly wrong with their math. Solar energy reaching the earth's surface averages about 150 watts per square meter for a panel always mounted perpendicular to the sun (when it's up), averaged over a year*. Assuming their panel is a meter wide, and always pointed at the sun, it makes sense that the power INPUT to the panel is 'about 210 watts' per day, not its output. At 15 percent efficiency, that would give them 32 watts per day per panel. Twenty panels would give them 640 watts per day, on average. That's about a dime's worth of electricity per day. Not very many people could heat and electrify their homes for three bucks a month worth of electricity.

* Wikipedia - "Sunlight" - "The World Meteorological Organization uses the term "sunshine duration" to mean the cumulative time during which an area receives direct irradiance from the Sun of at least 120 watts per square meter.[1] Other sources indicate an "Average over the entire earth" of "164 Watts per square meter over a 24 hour day"

Now they are going to want to cover everyone else s property with their collectors.
