Green Ammonia

What is ammonia?

Ammonia (NH3) is a naturally occurring chemical found in air, water, plants, and animals. It is comprised of nitrogen and hydrogen atoms, and even though it occurs naturally in the environment, it is the second largest artificially produced chemical in the world.


Ammonia holds 9X THE ENERGY of Lithium-Ion Batteries


Ammonia has 1.8X THE ENERGY DENSITY of Hydrogen


liquid at -33°C

Ammonia is LIQUID AT-33°C compared to -253°C required for Hydrogen

carbon-free fuel

Ammonia does not contain carbon so it produces ZERO CARBON EMISSIONS from combustion.

Ammonia will be part of the SOLUTION TO DECARBONIZE hard-to-abate sectors.

Ammonia's Global Impact

Why should we care about ammonia production?

  • 98% of the world’s ammonia is manufactured from fossil fuels.
  • 253 million metric tons of ammonia produced.
  • 500 million metric tons of CO₂ emitted from ammonia production. 
  • 1.8% of global CO₂ emissions come from ammonia production. 
  • 90% of the ammonia-related carbon emissions are from the production of hydrogen from methane (CH₄)
Green ammonia will be the future of ammonia manufacturing.

ammonia Production

Ammonia is manufactured using the Haber-Bosch process, which synthesizes Ammonia (NH3) from Hydrogen (H2) and Nitrogen (N2). Nitrogen is an inert gas abundant in the air we breathe, and hydrogen is the most abundant element in the universe. However, hydrogen rarely exists in its elemental form, and obtaining hydrogen requires extracting it from another source, called a hydrogen carrier.

When hydrogen is obtained from hydrocarbons, such as natural gas or coal, the carbon constituents leftover combine with oxygen and form carbon-dioxide, a critical greenhouse gas. Hydrogen can instead be separated from water through a process called electrolysis, which is a completely carbon-free process. This is called green hydrogen.

Ammonia made from green hydrogen is called green ammonia. 

The process for obtaining hydrogen is denoted by a color. Even though ammonia is always a clear, colorless gas, it is denoted by a color prefix dependent on the hydrogen source. 

In the US, 92% of ammonia produced is “Gray”, generating millions of tons of carbon emissions each year.

fuel, move, grow

Green ammonia has three primary use cases: Fuel, Move, and Grow. 80-90% of ammonia produced is used for agricultural fertilizers, but as the world moves toward sustainability, a growing proportion of ammonia will be used for alternative fuels and for hydrogen transportation.

Green ammonia is the best zero-carbon shipping fuel for long haul maritime operations, including cargo ships that supply most of the world’s goods.


Green ammonia is the best carrier of green hydrogen, enabling the transport of renewable energy around the world.


Green ammonia is a zero-carbon fertilizer for high nitrogen requiring crops, such as corn, wheat and soybean.
