Is Hydrothermal Hydrogen a Great Candidate?

There has to be some mechanism that simulates or drives this proton motive force. So hydrothermic, van hypothermal, hyprothermal events look like a great candidate. These vents are produced by a reaction between rock and water on any wet, rocking planet. And so if these ideas are correct, ana explains immediately why bacteria and arcaa independently have these same properties. They're usingtte to react hydrogen and carbon dioxide to make organic molecules. It's imaginable that life could operate in a different way. But because these conditions are so common, ubiquitous, it's likely that you would have similar constraints on life arising on other planets for similar reasons.
