Yes. Green ammonia can be produced in fully off-grid projects, provided that the overall energy and process design is carefully planned.

The main challenge is the instability of renewable power generation. Wind and solar resources can fluctuate by hour, day, and season. This affects the operating strategy of the hydrogen production unit, ammonia synthesis system, storage system, and control logic.

For off-grid projects, developers need to consider whether to include battery storage, hydrogen storage, or other buffering systems. They also need to evaluate whether the ammonia production unit will run continuously, operate at variable load, or follow the renewable power profile. These decisions directly affect equipment sizing, operating cost, system complexity, and project economics.

KAPSOM has developed solutions for off-grid and renewable-based green ammonia projects. For this type of application, the key is to design the plant as an integrated system rather than treating renewable power, hydrogen, nitrogen, and ammonia synthesis as separate parts.
