Ammonia has been proposed as a clean fuel for ships, airliners, trucks and trains, but China's GAC believes it could also have a future in passenger cars. It's built a combustion engine to test the theory, capable of reducing emissions by around 90%.Ammonia (NH3) carries hydrogen better than hydrogen carries hydrogen, in some regards. It's easier to handle, since it's liquid at ambient temperatures, and it thus doesn't require energy-hungry compression or cryogenic liquefaction gear. You can make it cleanly – although…
