The Application dimension of Methanation segmentation distinguishes four primary end‑use categories that together shape the market’s revenue composition. Power‑to‑Gas (PtG) accounts for the largest share, driven by grid‑balancing needs and surplus renewable electricity conversion, contributing roughly 45 % of total sales. Synthetic Natural Gas (SNG) follows with an estimated 30 % share, reflecting its role in replacing fossil‑derived gas in residential heating and industrial processes. The Chemical Feedstock segment, representing about 15 % of the market, supplies methanol and ammonia producers with renewable carbon, thereby extending the value chain into petrochemical applications. Finally, the Fuel Production niche, encompassing marine and aviation synthetic fuels, holds a modest 10 % share but exhibits the highest projected growth rate due to stringent decarbonisation mandates. Collectively, these application sub‑segments define the demand profile for reactors, catalysts, and engineering services, and their relative weights are reflected in the accompanying pie‑chart.
