Fuck hydrogen. Its a fake green product so oil companies can transition as slow as they want while still keeping their strangle hold on our society.

It depends a lot on where the hydrogen is sourced from. Hydrogen that is generated from electrolyzers using renewable power is completely green (and funny enough, called Green Hydrogen), and is a good way to store excess energy from solar and wind.
Oil companies however want to market hydrogen from drilling and refining, which is dirty as hell.
It's an important differentiation to make though. Hydrogen is not inherently bad and will have plenty of green applications. We just have to make sure it's coming from the right places.
Sadly almost all hydrogen currently making its way to market is dirty. I have high hopes for it in the future but it seems like thinly veiled poison at the moment.
And this article is definitely about the dirty kind or at least feels like it is.
There's companies working on it! ~~We're just broke~~
And yes, this is definitely the dirty kind. It may still be an improvement on using natural gas directly, but there would need to be a fairly comprehensive analysis to tell for sure. One possible advantage though is we could start building up a hydrogen infrastructure that we can then feed green hydrogen into and completely replace the dirty hydrogen.
Anyway though, you're right to be skeptical. It's important though to look into the details to determine if it's legitimately green energy or if it's just oil companies greenwashing. We need to shun the latter while we promote the former.
(There is a grey area, and it's the same as electric cars -- if we're using electricity from the grid to power cars, and electrolyzers which make hydrogen, is it truly green? I would say this is acceptable for the same reason EVs are acceptable. It'll become completely emission free once the grid is run on renewables.)
and is a good way to store excess energy from solar and wind.
Is it really that good of a storage method, though? The round-trip efficiency is quite bad when compared to other methods of storage.
We'll need it anyway to produce existing chemical materials sustainably. It may not be the best energy carrier nor most efficient, but it shines in specific applications. Vehicles are a promising example.

"That good of a storage method" in terms of what, arbitrage? We should be producing hydrogen for the practical and environmental benefits of having emissions-free vehicle fuel (that avoids the problems of battery production and disposal), steel, and fertilizer.

I disagree. We need hydrogen for GHG-free fertilizer and steel production and it's the superior choice for powering vehicles. Regardless, this research is interesting because it could help solve the natural gas problem.
Hydrogen from gas fields is anything but GHG-free!
That's why processes that capture or avoid the GHG component of hydrogen production are worth investigating.
Ok, but what about the ecosystems dependent on that chemical energy staying underground?
Are you implying that there are subterranean ecosystems somehow dependent on natural gas deposits that are harmed by the exploitation of these resources?
These ecosystems are well studied.
This isn’t controversial in the slightest. We are destroying unique ecosystems with every barrel we extract.
That's fascinating. Thank you for sharing. I guess these specific bacterial ecosystems would suffer, so to speak. Perhaps there should be rules to prevent oil and gas deposits from being completely depleted, or some could be set aside as nature preserves.
Massive green hydrogen plants running on renewables now being built in Australia but hey keep being part of the problem instead of the solution.
We're about to make Fracking look like a great idea 😂
Wait. Am I getting this right? They want to inject high-pressure steam and chemicals into a massive underground natural gas reservoir. Then set off a big fire + explosion.
Surely, nothing can go wrong.
It's called in situ combustion and apparently it's a well established practice in the petroleum industry: https://glossary.slb.com/en/terms/i/in-situ_combustion
So is coal extraction. How long has that coal fire burned under that town? 60 years?
You can read all about the Centralia mine fire here. ISC for oil extraction, as referenced by the paper, is not applicable to coal mining.
You miss their point
I do. I hope they will explain.
To spell it out for you, Just because something is well established in the industry does not make it good.
I never said it was good. I said it was a well established practice in response to @fubarx@lemmy.ml who seemed surprised that anyone would even consider it. I was surprised to learn about it as well, but it makes sense to use the oil or gas in the deposit to directly help fuel the process.
MANY WELL ESTABLISHED practices are horribly stupid...
See the many natural disasters caused by company standard practices.
-
Dumped raw toxins directly into rivers
-
Locking the doors on clothing factories
-
Fracking
None of those things are in situ combustion thermal recovery. It may well be that this method isn't appropriate for the process described in the paper. The paper also suggests RF thermal recovery as an alternative. The process just requires additional heat besides the steam to affect the SMR reaction and get the hydrogen out.
No but they all claim their business practices were safe...
The water dilutes and carries the toxins away. Until the river catches fire..
If there's a mine fire just close up the entrance and it'll go out. Except it hasn't for 60+ years.
Fracking can't cause earthquakes, except it does and there is evidence the chemicals could actually be getting in ground water... This one is particularly interesting. Considering they claim this process is safe.
But I doubt you care about facts.

First of all, they spelled Heelys wrong. Second, Heelys are a great idea, even better as an adult in an office with polished concrete floors.
Yes because igniting fires underground is a GREAT idea!
Centralia,PA would like a word...

What could possibly go wrong?
This worst case scenario is probably the same as with any reservoir of natural gas (a massive leak and explosion), which is all the more reason to convert it to hydrogen and sequester the weaker, non-flammable GHG byproduct in situ.
I imagine that suddenly all the co2 stored as gas underground could suddenly come out and being odorless, kills the whole neighboring town
Natural gas is also odorless and able to displace oxygen so I don’t see how it being CO2 underground instead of natural gas changes anything from a risk perspective. Maybe because the molecules are smaller and thus more prone to leaks? I’m admittedly way out of my depth here.
Methane is lighter than air and goes up while co2 is heavier than oxygen and stays down. I don’t know maybe in case of some disaster where water leaks in the well and then pushes out the co2
I wouldn’t want to live nearby in both cases anyway
I'd be worried about the now excess co2 levels disrupting the normal saturation levels in the groundwater.
Sparkling water, on tap!
It's what plants crave I guess.
This how you realize that there are people around that just want to blow shit up.
Yeah, something about this screams at me it's not right.
Why wouldn't this work? What would go wrong?
Producing hydrogen from natural gas still releases carbon in to the air.
...which is the whole reason for doing the SMR within the natural reservoir and leaving the CO~2~ in there.
We could just give up on the idea that natural gas is “clean.”
That used to be my thinking, but there's a lot of natural gas ready to be exploited and we need hydrogen. Therefore, methods like the one described in the article as well as ex situ methane pyrolysis are worth investigating.
but there's a lot of natural gas ready to be exploited
Sooooo money. That's the exception to doing the right thing?
