Hydrogen Might Self-Renew, Reservoir found in France

Several recent discoveries of naturally occurring hydrogen reservoirs underground (the so-called "white hydrogen") have prompted the whole world to start searching for more of the stuff. Even though this seems like a gamechanger for the hydrogen economy, I am still sceptical of its viability economically, energetically, and environmentally.

As a metallurgist I was thrilled at the mention of hydrogen embrittlement...finally something I understand.

Burning H2 made from methane is just burning methane, with extra steps

Why do physicists always think geologists say things we don't?

The crust (volumetrically and mass wise) has almost no free carbon to react with. What carbon is in the crust, is almost entirely locked up in carbonate rocks. So why would we think there couldn't be hydrogen?

Please try to explain the connection between Charm Quarks and entanglement and space-time? Hear me out... In a blister on my skin, the skin is curved around the fluid in the blister. The skin itself has an internal structure of course. And the skin defines a boundary between "inside" and "outside." The fluid that makes the blister comes into the blister after moving through pores in the skin... and there the metaphors breaks down... So my question:

Are there any models that try to explain how mass gets into the black hole that forms the blister in space-time? Where does the mass go when the blister (black hole) evaporates? Where do those charm Quarks come from and disappear to? Don't we need another medium or state to explain these externalities? Feels like entanglement, too, needs to get outside space-time? Seems like space-time defines a boundary between inside and outside, but I don't know of what models might use this kind of structure... Do you, by chance?

From my nuke plant training: H2 will not burn or explode below 4% or above 75% concentration in air at STP.
It will explode at 59% concentration in air at STP although there is a range of concentrations that can cause a degree of deflagration from burning to violent explosion.
It's definitely a dangerous proposition if the concentration gets to high.

Really elegant and structured summary of a complicated subject! The best!

My experience was converting vehicles in the early 1990s to propane and NG. The problem with NG, as is with hydrogene, is the efficient storage. At the time we were using spun aluminum tanks. They weighed multiple times that of contents because of the pressure increase, when cooled liquid hyrogene was stored in a not cooled container.
Those tanks had to withstand about 3000psi and a drop from a specified height. Left that business 30 years ago, and have no idea if cheaper materials of less weight and less costly production methods are now available.

Even if you can get the hydrogen out of a well which was basically created for free, that still leaves you with the transport and storage problem. While I personally wish we did use hydrogen, it still does not really seem to be practical relative to other available options. Especially when we consider the glut of solid state batteries ready to drop on the market.

That was not in southern France, but in Moselle, near Folschviller.

I previously was involved in hydrogen reactor research for the chemical industry, and the introduction you provided in this video is excellent!

I highly recommend this channel to everyone who wants science news presented in a dispassionate way that relies upon actual data and quality studies to support arguments.

[robertphillips]

I really like the inclusion of a quiz to let me check that I was talking the information in. Keep up the great work. Thanks!

Small correction, at 4:39 Sabine mentions forsterite (Mg2SiO4) as being iron rich, this in not the case as it contains no iron. She probably meant fayalite (Fe2SiO4). Forsterite and fayalite are the end-members of the solid solution that is olivine ((Mg, Fe)2SiO4).

[woodennecktie]

it always surprises me that all science can come up with is burn burn burn, while hydrogen is a great building element to create carbon hydro fuel .... so using the carbon to transport and use hydrogen as a fuel to run internal combustion engines that propel contraptions we currently name as cars and trucks . the hydrogen can be a good solution in geografical logistics (aka transport)

6:46 Because 10 is almost twice as much as 2?

[williamschrom]

You are still one of my favorite people on this planet... always have been.

When i did my PhD on hydrogen oxygen flames i had frequent small explosions. The invisible flame was also an issue, still it would be exciting if we had lots of it. The guy who wrote Smelling Land painted a great picture which so far has not occurred.

[alieninmybeverage]

When we find all these hydrogen deposits, we can build launch pads atop them for clean, renewable, get-out-of-dodge energy. Very farm to mouth.

Thank you for this video and for sharing knowledge.

there are catalysts that make electrolysis more efficient (cutting the activation barrier in half or more) - it was well understood in simulation on graphene with vacancies but also in the past was done with steam over coal
