Comment on How is the hydrogen made?

  The attack-🪿 is asking BP how the hydrogen is made because it’s an important question.

  Hydrogen can be made multiple ways.

  1. Split water (H²O) with electricity. You get ⅔ H and ⅓ O. When you burn the H you’ll get water back and ⅔ the energy you put in. In this way it can actually as a poor battery.

  2. Take Methane (CH⁴), the major part of natural gas and split it. You get ⅘ H and ⅕ carbon. So you’re releasing the same carbon that you would release if you just burnt the methane, and you’ll get less energy too. Then take away the energy it took to split the methane and you’re a lot worse off for no saving in carbon.

  3. Other oil and gas based sources, but that follow the theme of methane.

  Only the first one is “green”, and only if the electricy comes from a green source (like solar or wind). Burning gas to make electricity to make hydrogen is stupid.

  Oil and gas companies companies keep pushing hydrogen as green power, but really they want to keep selling oil and gas, and if they need to convert it into hydrogen to do it, that’s fine in their eyes. Doesn’t matter if they are still pumping carbon out of the ground. Doesn’t matter if it’s less efficient. It’s green washing plain and simple.

  Attack 🪿 is asking the question that would make them admit this.

  That thread was full of people complaining that nobody was doing anything with hydrogen and it was stupid to power cars from electricity directly. They are all just O&G company shills

    Thank you, I appreciate you took the time to write this out and provide context. I was only aware of the water method but that makes sense.
