mmonia is a crucial ingredient for the planet’s food supply—more than two-thirds of it is used to produce fertilizer. It’s also increasingly being seen as a potential clean energy source, with startups like Amogy using it to produce power for maritime and industrial applications. But while burning ammonia for fuel may be clean, making it isn’t—it relies on a fossil fuel dependent chemical reaction called the Haber-Bosch process, which accounts for nearly 2% of carbon emissions annually.
