And the current source of electricity that runs HN is most probably fossil fuels. Does it make HN "petro-website"? It's clearly a derogatory term that serves no constructive purpose. I believe we should strive for zero-emission hydrogen production (which is clearly possible given that hydrogen can be easily used to utilize excessive production from "green" sources) instead of pushing luddite worldview.

The key point of my post was "the current source of hydrogen for ammonia is natural gas" It can be made from other sources, but it is not. Hence petro-chemical. Like plastic or nylon.
