I Escape of Hydrogen from the Earth's Atmosphere

AI Thread Summary
The discussion centers on the escape of hydrogen from Earth's atmosphere and its implications for future hydrogen use as an energy source. Participants explore whether hydrogen can be retained between the Earth and the Moon due to gravitational effects and question the actual loss of hydrogen from the atmosphere. There is a mention of the solar wind's contribution to atmospheric hydrogen and the potential transformation of atmospheric agents back into water. The conversation also touches on the role of Earth's magnetic field in deflecting energetic particles, including protons and alpha particles, and their interactions with the atmosphere. Overall, the topic highlights concerns about hydrogen loss and its impact on water availability as hydrogen energy becomes more prevalent.

Hi ! I ask you two questions:

1- If hydrogen escapes from the Earth's atmosphere as it happens, because if there are anaerobic bacteria that produce hydrogen naturally among some other living beings, because among the thousands and millions of years that life has been on earth, hydrogen was not finished and the existing water in the Earth's crust?

2- The escape velocity of hydrogen is similar to the escape velocity of the Earth but apparently there are certain thermal and non-thermal escape mechanisms that would facilitate the escape of hydrogen from the atmosphere when it is in the upper areas of the Earth's atmosphere, but I wonder, if the force of gravity of the Moon would not help to retain the Hydrogen in the region of space between the Earth and the Moon, so that the Hydrogen does not really escape from the Earth and remains in the space between the Moon and the Earth, and later eventually return to Earth. Can this happen?

I will thank you for your answers because I think this is an interesting topic in the present considering the possible use of hydrogen as an energy vector and its production from the electrolysis and dissociation of water and that if there are losses of hydrogen in handling and in the use of the same would have losses of water from the Earth's crust that would be the most complicated of the use of hydrogen as an energy vector and its sustainable use over time.

I thank you for your responses and send you greetings.

Your question doesn't make sense to me. If hydrogen leaks from the power generating apparatus, it is lost for energy production whether or not it stays in the atmosphere or goes off into space. Perhaps you can explain better the reason for your question about space.
 
My main interest is the loss of hydrogen and consequently of water from the Earth's crust that may occur in the future with the use of hydrogen as fuel in some applications.

Also, my question is whether or not hydrogen is currently escaping from the Earth's atmosphere really.

Perhaps not surprisingly there is a Wikipedia page on loss of the Earth's atmosphere. And lots more online material as well.
 
Hi Perok !

Yes, I have looked for information on the internet and in Wikipedia on this topic and in general they talk about of that Hydrogen escapes from the Earth's atmosphere, but I have doubts about whether the atmospheric escape of Hydrogen actually occurs, so I asked it here too.
 
How much hydrogen arrives from the Sun in the solar wind ?

I don't know about this. But thank you for your response.

Alpha particles ( Hydrogen nucleii) should be deflected by Earth's magnetic field.

You mean helium, He, surely.

According to this analysis, although there would be greater amounts of agents that absorb hydrogen from the atmosphere and transform it back into water.
The escape of hydrogen from the Earth's atmosphere would also occur, right?

The majority may be deflected but there is a directional window for some that reach and react with the atmosphere.
Alpa particles = energetic Helium nucleii.
Protons = energetic Hydrogen nucleii.

Damnation.
Ya. I do.
I mean protons should also be blocked. Lol

Ok. Thank you for pointing that out.
Could you elaborate the direction tho, please.
And yes I made a mistake on alpha particles.

Thank you tho

Maybe too the entry of Protons into the atmosphere in the form of rays or cosmic rain, perhaps later it can form Hydrogen atoms in the Earth's atmosphere. Does it seem correct?
