Local Ammonia Production, Global Impact

The Challenge

Ammonia is the world’s highest-volume commodity chemical and the foundation of modern fertilizer. Today, it is produced almost entirely using the fossil-fuel-based Haber-Bosch process, which accounts for roughly 2% of global greenhouse gas emissions. Because the process is only economical at massive scale, production is centralized in large facilities located far from farms, resulting in high transportation costs and supply chain inefficiencies.

Technology

Our Chemical Looping Ammonia Synthesis (CLAS) technology produces ammonia using a recyclable carrier material in a looping cycle. Nitrogen and hydrogen are alternately reacted with the carrier, enabling ammonia synthesis under milder conditions than Haber-Bosch. This approach improves energy efficiency and makes smaller, modular production systems economically viable.

Impact

Improved Supply Chain Resilience

Distributed, local manufacturing reduces reliance on centralized production and long-distance transport.

Reduced Environmental Impact

CLAS enables the use of local clean energy sources and low-carbon feedstocks, significantly lowering emissions.

Reduced Costs

Producing ammonia near end users eliminates transportation costs that can rival the cost of manufacturing.
