Researchers at Stanford University and King Fahd University of Petroleum and Minerals have developed a method of producing ammonia at room temperature and at standard atmospheric pressure, without electricity. Scaling up the technology would eliminate the need for the Haber-Bosch process, which contributes to 1.2% of global GHG emissions when producing the high pressure and high temperature needed during the process. This new method extracts nitrogen and hydrogen from water vapour in the air using a mesh coated with catalysts.
