Driving the green ammonia revolution

Ammonia production is a major contributor to global greenhouse gas (GHG) emissions, accounting for around 2% worldwide. This is because conventional “gray” ammonia is made from carbon sources, like natural gas and coal.

In contrast, green ammonia is produced from renewable energy, water and air-captured nitrogen, so in the best case there are no CO2 emissions. By transitioning to carbon-free green ammonia production, we can significantly reduce the environmental impact of a base chemical needed for vital applications, such as fertilizer production.

Green ammonia: the sustainable fuel powering the energy transition

In addition to its traditional uses, green ammonia promises to be a game-changer in the decarbonization of the energy industry. It produces no carbon dioxide when burned, making it an ideal clean fuel for shipping, and heavy road transport.

Ammonia is also a highly efficient hydrogen carrier. Thanks to its chemical composition and high energy density, ammonia can transport hydrogen over long distances via existing infrastructure from renewable energy hubs to points of use.

With versatile applications in transportation, power and hydrogen supply, green ammonia is expected to play a critical role in the world’s energy transition.

Solving challenges in green ammonia production

The transition to green ammonia faces initial challenges, such as higher upfront costs compared to conventional gray or blue ammonia production, and fluctuating feed conditions due to the intermittent availability of renewable energy. Therefore, a catalyst that can optimize efficiency and overcome challenging process conditions, including exposure to oxygenates, is essential for reliable, cost-effective green ammonia production.

By offering innovative catalyst solutions tailored to the use of renewable hydrogen, Clariant can unlock the full potential of green ammonia and accelerate the transition to carbon-free fuel supply and sustainable chemical production.
