Ammonia (NH3), the colourless, pungent gas, is an excellent source of hydrogen in its liquid form, containing twice as much hydrogen as liquid hydrogen by volume. Liquid ammonia can be stored in large tanks at room temperature and is as safe as gasoline and safer than propane. Around 230 million metric tons of ammonia are produced each year. Conventionally made ammonia is already stored and handled in 120 ports around the world, meaning it is easily accessible and available for shipping.
Ammonia compared to fossil fuels
Gasoline fossil fuel is easily accessible and relatively inexpensive. However, it is highly polluting to the atmosphere and to the soil. Like diesel, ammonia is a readily-available liquid fuel and has widely developed transportation and logistical infrastructure. But ammonia is superior to diesel as it is significantly less expensive than diesel and does not pollute the environment.
