Ammisorb
Ammisorb provides a patent-pending ammonia extraction technology called the Sorption Booster that makes decentralized green ammonia plants economically viable. The system uses a staged sorption cycle operating below 50 bar with no cryogenic refrigeration, achieving over 99% single-pass extraction efficiency. This modular, synthesis-agnostic unit is designed to integrate into sub-100 TPD plants for fertilizer, maritime fuel, and energy storage applications.

Problem
Decentralized green ammonia plants remain economically unviable because the conventional ammonia extraction step relies on cryogenic condensation at very high pressures—physics that only pays off at gigascale. At sub-100 TPD scale, this single step can absorb up to a quarter of total capital cost and more than 20% of operating costs, typically preventing projects from reaching final investment decisions.
Solution
Sorption Booster provides a patent-pending staged sorption cycle that captures ammonia at moderate pressure and temperature, replacing the expensive compress-and-chill separation stage. The process uses a proprietary sorbent to selectively bind ammonia from the synthesis loop at below 50 bar and near-ambient temperature, achieving over 99% single-pass extraction efficiency. A mild thermal swing regenerates the sorbent and releases concentrated ammonia without cryogenic compression, while hydrogen and unreacted nitrogen return to the synthesis loop with negligible loss. The modular unit sits downstream of the synthesis reactor and is synthesis-agnostic, designed to integrate into other companies' plant designs without competing with synthesis technology providers.
Target Audience
Primary customers are developers and system integrators building decentralized green ammonia plants at sub-100 TPD scale, ranging from fertilizer producers to energy companies pursuing ammonia as a hydrogen carrier and maritime fuel.
