Ammonia – Efficient Hydrogen Carrier, Advantages
In an article posted in ChemEurope, it is given that ammonia can be a good hydrogen carrier. The article conveys that
- Ammonia can also be used for direct reduction of iron that helps ammonia overcome any deficiency in hydrogen
- In contrast to hydrogen-based reduction, nitrides form during cooling in ammonia, which could protect the sponge iron from corrosion and make it easier to handle.
- Liquefaction cost for Ammonia is low.
- Ammonia can be directly used to reduce iron ores without cracking it into hydrogen and nitrogen. Avoiding this cracking process can reduce the overall costs by 18%.
