The Future Fuel of the World is Green NH3

Green hydrogen projects are multiplying with exponential space around the world.

What is green hydrogen?

It is hydrogen gas produced by electrolysis powered by renewable energy, like solar and wind.

Hydrogen, H2 is a highly volatile gas. It is expensive and hard to store it safely. If we combine 3 hydrogen atoms with one nitrogen atom --, available from the air then we created ammonia, N2 + 3H2 → 2NH3. We are already doing it in large scale industrial production for more than 100 years, it is called the Haber-Bosch process. Liquid ammonia or anhydrous ammonia is much less expensive and easier to store and transport.

Using an ammonia cracker and a hydrogen fuel cell electric generator, we can change back the NH3 to electrical energy where we started originally. Ammonia is an effective way to store and transport renewable energy. Ammonia has a relatively high energy density, 22.5 MJ/kg. To compare this number --, crude oil has approximately 45 MJ/kg. However, green NH3 is much cleaner than crude oil!

Interestingly, Jet A-1 fuel has approximately 43.15 MJ/kg. One day airplanes may use liquid NH3 as a fuel source.
