Ammonigy & Juwö Poroton: cracked ammonia fuel for brick manufacturing

Kevin Rouwenhorst November 27, 2025

In our November episode of Project Features, Juwö Poroton and Ammonigy joined us to explore their “CO₂-free brick production” project, demonstrating the use of cracked ammonia fuel to fire bricks in Wöllstein, Germany. Though hurdles remain for the deployment of the solution at the necessary scale, promising operational results and quality-checked final products were achieved, and progress is being made towards emissions mitigation.

Ammonigy, Heraeus: successful four-stroke engine demonstration

Julian Atchison July 23, 2025

Ammonigy, Heraeus Precious Metals and the Technical University of Darmstadt have partnered to demonstrate operations using cracked ammonia fuel in a four-stroke MAN test engine. The performance and efficiency of the test engine when running on ammonia-hydrogen fuel was comparable to natural gas operations, and use of an exhaust aftertreatment system reduced potentially harmful nitrogen-based emissions to near-zero levels.

Cracked ammonia: fuel gas for brick production in Germany

Julian Atchison July 23, 2025

Ammonia cracking tech provider Ammonigy and leading German brick manufacturer Juwö Poroton led the project, successfully demonstrating a pilot-sized brick kiln that runs on cracked ammonia fuel gas. The cracked ammonia-fired bricks were virtually “indistinguishable from bricks fired with natural gas”.
