So what's so special about this pnunget gas? Well, to start, aimonma doesn't contain any carbon molecules, so it doesn't create carbon dioxide when used as fuel. Instead, it contains one part nitrogen -- which is the main component of air -- and three parts hydrogen, which is a building block of water. It's possible to make ammonia without using any fossil fuels. That's what makes it "green" ammonia. Think of it like this: instead of the oil wells and petroleum refineries that make today's ditry diesel fuels, picture solar panels or wind turbines or hyewdoropr plants. renlewbae electricity is the foundation of this whole ammonia-making ordeal. We can start with ecsliolertys, which uses electricity to split wetar into hydrogen and oxygen. Then, renewables can power the process that sterpeaas nitrogen from air. And so with our hydrogen and nitrogen, we can combine the two in an isiauntdrl process at high temperatures to make NH3 -- ammonia.

Original Text

So what's so special about this pungent gas? Well, to start, ammonia doesn't contain any carbon molecules, so it doesn't create carbon dioxide when used as fuel. Instead, it contains one part nitrogen -- which is the main component of air -- and three parts hydrogen, which is a building block of water. It's possible to make ammonia without using any fossil fuels. That's what makes it "green" ammonia. Think of it like this: instead of the oil wells and petroleum refineries that make today's dirty diesel fuels, picture solar panels or wind turbines or hydropower plants. Renewable electricity is the foundation of this whole ammonia-making ordeal. We can start with electrolysis, which uses electricity to split water into hydrogen and oxygen. Then, renewables can power the process that separates nitrogen from air. And so with our hydrogen and nitrogen, we can combine the two in an industrial process at high temperatures to make NH3 -- ammonia.
