The Application dimension of the AMMonia-d3 market is divided into four principal segments: fertilizer production, power generation, refrigeration systems, and water‑treatment processes. Fertilizer production accounts for the largest share, roughly 45 % of total revenue, reflecting the high demand for nitrogen‑based inputs in global agriculture. Power generation, driven by ammonia‑fuel‑cell and combined‑cycle technologies, contributes about 30 % of market size, indicating a growing shift toward low‑carbon energy sources. Refrigeration systems, which exploit the high latent heat of vaporization of ammonia, represent 15 % of the market, while water‑treatment applications, including ammonia‑based stripping and nitrification control, hold the remaining 10 %. These proportions are illustrated in the accompanying pie chart and together define the overall AMMonia-d3 segmentation landscape.
