H2ACT®

Unlocking the Global Hydrogen Economy Through Ammonia Cracking

Ammonia is an ideal energy and hydrogen carrier – energy-dense, easy to transport, with an established global infrastructure. To unlock its full potential, we need a technology that can efficiently and sustainably provide hydrogen at the point of use.

KBR's H2ACT® technology converts ammonia back into high-purity hydrogen at industrial scale, enabling a practical pathway for global hydrogen trade and helping bridge the gap between hydrogen production and demand.

Proven. Commercial. Ready to Scale.

Ammonia, a zero-carbon molecule with high hydrogen-storage density, is the most promising long-distance energy carrier in the short to medium-term

The world's lowest-cost renewable energy resources are often located far from the regions where hydrogen demand is growing.

While hydrogen itself is difficult and expensive to transport over long distances, ammonia offers an established, scalable alternative.

Why Ammonia?

Higher volumetric energy density than liquid hydrogen
Existing global shipping and storage infrastructure
Well-established international trade routes
Ability to transport large quantities across continents
Cost-effective long-distance hydrogen carrier

Ammonia is rapidly becoming the preferred molecule for global hydrogen transportation because it combines the advantages of existing infrastructure with the ability to store and transport hydrogen at scale.
