- In France's eastern Lorraine region, scientists have uncovered vast deposits of natural hydrogen, one of the cleanest fuels in nature. The discovery could be the biggest of its kind so far, spurring a global energy race for the fuel of the future. The Down to Earth team takes a closer look.

What do they propose to do with the 80% that is Methane? Burning the
Hydrogen is carbon free, Methane is 100 as potent a greenhouse gas as CO2. For every volume of hydrogen produced you will obtain 4 volumes of methane. 🤔
As you go deeper the content of hydrogen increases, at 3000m they expect to hit 100% hydrogen reservoir
You can leave it be. You basically go deeper like in Africa where the first hydrogen well was accidentally discovered which goes as pure as 98% with 2% being helium which is also a sought after resource. Same goes for in Australia where they found around 70% after a certain depth and increases the deeper they go, going deeper will increase the purity as hydrogen tends to bond with other things the shallower you go. The depth tends to be area specific as the one on Africa actually is just around 300 meters deep with 98% purity.
Last 3 minutes of the video explains it.
When this mixture is burned, it should have significantly lower emissions per MWh than natural gas as 20% of it is hydrogen and that hydrogen has about 2 times more energy than natural gas. Now natural gas can have bit of hydrogen and other gases added, but let's omit those for simplicity. Natural gas has energy of about 14 kWh per kilogram, for hydrogen it is about 33kWh per kg, so this mixture should have about 17.8 kWh per kg. Emissions from burning of natural gas are bout 0.2kg per kWh, this mixture has thus only about 0.16kg per kWh, and we have to multiply it by another 0.8 in order to get back to roughly 14kWh per kg, so, the total emissions would be, if all my calculations are correct, 0.128kg per kWh, reduction of about 36 % from just this mixture compared to NG. I would say that even just this mixture is enough to significantly reduce carbon footprint of energy production.
But there is another thing to this - energy independence. Currently we source natural gas in certain locations that do not exactly match where most of the people and industry are. So if hydrogen deposits will be in different locations than will at least partially match with distribution of industry and population, energy security fo the world could be significantly increase. Not to mention that if significant deposits would be discovered in the Europe, it could reduce it!s dependence on imported fuels. and thus reduce emissions associated with the transport.
They won't just release the methane as its rather obvious...They can literally just extract it to, and use it, as it will be of lower carbon intensity then nat gas. And use the hydrogen to
The hydrogen is in low concentrations. These are not gaz deposits. It remains to be demonstrated that the hydrogen can be extracted economically and in significant quantities.
The only hydrogen being exploited is in Mali and in small quantities. The hydrogen is used to generate electricity for a small village.
Let's wait until a significant hydrogen gas deposit is drilled and extracted before making bold claims.
I dont think youve read enough on the Mali discovery, youd think otherwise. Recent exploration in Albania show high concetrations which can be economically viable. There are a number, they just havent been in the limelight. H2 is the new fuel!
Fascinating! I wish France the very best of luck in securing and using these resources. You (France) is infinitely more trustworthy than the majority of fossil fuel producers and goodness knows we (the world) need to wean ourselves off using fossil fuel as ... well, a fuel! That doesn't mean we won't use "fossil fuels" to produce the plastics, medicines, solvents etc though the name is likely to change!
If anything, once large deposits are confirmed it is likely fossil fuel companies will pivot to extracting hydrogen instead if they want their companies to be alive once fossil fuel usage isn't as dominant. If I recall a lot of them like the video states are doing a wait and see approach. Them pivoting to natural hydrogen prevents huge loss of jobs and could reuse large portions of their expertise on gas extraction and drilling to better use imo. They also have large sums of cash to quickly increase exploration and extraction to make the transition faster.
well hydrogen hes always been there issue is it burns hotter then regular gaz and it makes metal pipes brittle..and storage is problem aswell
Umm, looks like a "WE DISCOVERED HYDROGEN!" kinda greenwashing for a coal mining company.
It's actually a reality, there's a precedent in Africa where they accidentally found a huge well with 98% pure hydrogen, 2% helium. It's powering a nearby village cleanly for a decade now since it was discovered, it's the main reason why white hydrogen has taken a lot of interest in the recent years. Geologists didn't think it was possible until they examined the well in Africa. Basically they realized were looking at the wrong place instead. It's basically a cycle where underground water interacts with a number of geologic events underground, particularly radiolysis and mineral oxidation.
NOOO there is not enough!!! Though it makes a good transition fuel
a 'transition' to what?
dream on
so how much is found?
potential enough for 3 years
The acidity that creates bogs is because of high hydrogen levels. It may very well be possible to harvest natural hydrogen from these wet acidic environments.
It's also the cause of the common fairy circles you see all over the globe.
lol! It just releases 'water vapor', which of course is the biggest greenhouse gas.
2024 and people aparently forgot what the water cycle is. It won't increase the ammount of water vapour in the atmosphere. Get to much water vapour in 1 place and it forms clouds (wich reflect sunlight during the day), and then rain. It won't significantly increase the ammount of water in the atmosphere
It'll need oxygen to burn. Why not split water, use the water as a battery, split it and combine it if you need energy.
Any other "solution" is not sustainable.
80% Methane and 20% Hydrogen. In order to get the 20% Hydrogen which is zero carbon, the company also has to extract 80% methane. Methane is about 80 times more potant for global warming than the standard CO2.
Just another excuse to stick to fossil fuel!!
It's still fossil fuel.
Just go deeper, concentrations do rise as you go deeper. As evidenced on the well in Africa that's spewing 98% clean hydrogen for over 2 decades now. The moment you find around 20% suggests there's a large reservoir below it, the 80% methane basically confirms the reservoir as hydrogen tends to bond with stuff at shallower depth. So you basically just need to go deeper to the part where it's still pure hydrogen and before it bonds to other elements on the upper levels underground.
@vinezero We've been using dangerous fuels for over a century. Relax buddy. 😂
@@ashleybasil2082 Completely wrong
Good start....the size of the resource discovered could supply 8% of the world's annual energy demand. Get back to work and keep drilling.
It is not renewable
But it will handle things enough time for renewable hydrogen and other alternative energy sources become more mainstream
@Maverick_42 intersting, do you have any reference on that, i would like to learn more
This is really cool but may not be a reliable source, Blue Hydrogen is Better.
O carbon oui hydrogen 👌👍
Thank you 🙏
finally a way to reduce atmospheric oxygen on a significant scale :)
4/5 methan of 250 million tons, as you say it may help ^^
That's in the part of Germany taken by France, France should share it with Germany.
That's the part of france that france REtook from germany after germany stole it from france in the 19 th century wars
This is what happens when you aren’t hijacked by the fossil fuel industry like the U.S.
Hope this is a real thing!🤞🤞
