I just listened to a podcast (50 things that made the modern economy http://www.bbc.co.uk/programmes/p04f77rg http://www.bbc.co.uk/programmes/p04f77rg) about the Haber-Bosch process https://en.wikipedia.org/wiki/Haber_process https://en.wikipedia.org/wiki/Haber_process
According to the podcast and the wiki page, the current source of hydrogen for ammonia is natural gas. Additionally the process is energy-intensive, using high temperature and pressure.
These things don't necessarily make it mandatory that it's petro-chemical, but due to the way we currently run it it is.

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.
- chadgeidel 10y agoThe 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.
