alt Hacker NewsSo basically: wind generators power electrolysis to create hydrogen, the hydrogen is fed to a normal Haber-Bosch plant which is still powered by coal or gas. So basically the wind power is just replacing the carbon footprint of a single input (hydrogen) to a H-B plant?

Why would the HB plant be powered with fossil fuels? You can power that with wind power as well.

The only chemical inputs a Haber-Bosch plant needs are nitrogen and hydrogen. The nitrogen always comes from air and in this plant the hydrogen comes from electrolysis. The plant also needs electrical power to run compressors, but that can also be supplied by wind and it's minor compared to the embodied energy of the hydrogen input.
