Hydrogen power is an exciting form of clean energy. But hydrogen typically needed to be produced in a lab using energy-intensive methods. White hydrogen, a newly identified hydrogen source, could eliminate the need for lab production.

    How would it be just as bad? Water doesn’t cause climate change.

    If we converted all of the CO2 humans have ever released into water, you’d get around 2.5 times lake superior. I don’t see how that would cause much issues.

        Yes, but the amount of it in the air globally is not increased by burning hydrogen. The processes that remove extra water vapor from the atmosphere operate on a much faster time scale than the ones that remove CO2.

        It wouldn’t be on it’s own though.

        Without other greenhouse gases kickstarting the warming process, just adding water vapor to the atmosphere just saturates it faster, slowing natural evaporation of the water cycle, which would eventually just move all the additional water to the ocean.

        The amount of water we’re talking about is insignificant given the already large reservar of water we have on earth. Also in the absence of other greenhouse gases, the water cycle is self regulating, it doesn’t act as a greenhouse gas in the absence of another sauce of warming (which then increases the moisture carrying capacity of the air, starting a feedback loop).

        CO2 is much more rare so adding that same amount in CO2 is very significant.

        It’s a bit like making a sauce. Adding a bit more of your main ingredient (for example cream in a cream based sauce) won’t make much difference to how it tastes. But add the same amount of a potent spice and your sauce is ruined.

      “at scale” it could be just as bad. C02 isn’t poisonous the big problem we’re dealing with is we’re putting C02 from the ground in oil and coal and putting it into the air. We’ve been adding C02 that was NOT in the environment into the environment.

      Yeah some water isn’t a bad thing, but if all of a sudden we’re adding from sources outside of the water cycle a LOT more water into the atmosphere you’ve got increased clouds, increased weather patterns, All of a sudden the inland portions of continents can start dumping as much water into the air as a warm ocean, that can DEFINITELY be a problem.

        Yeah, but we’re really talking a LOT more water here. Like Noah’s ark numbers.

        I was talking about an amount equal to what we so far added in CO2, which is would be an insignifcant amount when turned into water.
